In this study, high-strength carbon fibre (CF) was utilized to reinforce the aluminium (Al) matrix for fabricating the metal matrix composite (MMC). It was found that strain, strain rate and temperature gradient play a significant role in non-uniform particle distribution at the advancing and retreating sides of the processed regions. To address these challenges, Upward Friction Stir Processing (UFSP) with a threaded pin tool was proposed to assess the uniformity of the reinforcing carbon fibres on the advancing and retreating sides, which is the novelty in this study. The influence of UFSP tool offset direction on material flow characteristics and particle distribution were analyzed. Carbon fibre agglomeration and band formation within the metal matrix was given special attention during UFSP technique. A double-pass UFSP was introduced which revealed a homogenous dispersion of CF upon microstructural characterisation. Furthermore, results demonstrated a 36% increase in bulk hardness and 54% increase of electrical conductivity compared to base metal. Thus, incorporation of a 2 wt% of CF yielded harder and better electrically conductive UFSP-ed metal matrix composite. This is expected to have a wider application in industrial joining methods while joining of two dissimilar metals or metal based composites.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"30 11","pages":"3107 - 3126"},"PeriodicalIF":3.3,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141121823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this alloy is highly sensitive to hot workability and is crack prone during hot deformation. This study investigates the effect of hot workability parameters such as temperature, strain rate, and overall strain on the microstructure evolution. The hot deformability of this alloy was studied using isothermal hot compression tests in the temperature range of 850 °C to 1150 °C and at strain rates ranging from 10^− 3 to 10 s^− 1, using a Gleeble 3800 thermo-mechanical simulator. The flow behaviour was analysed using stress-strain and strain hardening plots. Initial microstructure of the material has as-cast dendritic structure, while microstructural analysis of hot deformed samples revealed gradual reconstitution with increasing temperature and decreasing strain rate. Hot deformed samples showed traces of recrystallized grains and carbides across the matrix at high temperatures and low strain rates. EBSD GROD mapping further elucidates the variation of microstructural features with variation of strain rate. In accordance with the Ziegler instability criterion, processing maps were constructed for a true strain of 0.65, encompassing deformation temperatures between 850 °C and 1150 °C, and strain rates ranging from 0.001 to 10 s^− 1. Through an examination of strain rate sensitivity map, processing map and analysis of deformation activation energy, both undesirable (unstable) and potentially favourable (stable) hot deformation parameters were identified. Instability regions in the processing maps were validated with the microstructural features of deformed samples of cast Monel K500 alloy.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"30 11","pages":"3155 - 3170"},"PeriodicalIF":3.3,"publicationDate":"2024-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141123669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, as-cast Mg-9.1Y-1.8Zn (WZ92) alloy was homogenized first and then hot extruded to regulate its mechanical and corrosion properties. The as-cast alloy composes of α-Mg matrix, Mg₂₄Y₅ eutectic phase and interdendritic 18R-long period stacking ordered (LPSO) phase, in which the continuous block- or rod-like 18R-LPSO phase can act as corrosion barrier to prevent the corrosion penetration. After heat treatment, the precipitation of intragranular fine lamellar 14 H-LPSO phase not only reduces the ductility of the alloy, but also provides channels for corrosion intrusion, thus severe corrosion pits are formed. First-principles calculation reveals that the 14 H-LPSO phase is more likely adsorbed with Cl atom, and chemical bonds are formed in the 14 H-LPSO/Cl interface, which results in the worst corrosion resistance of the homogenized alloy. Further extrusion improves the yield strength and ductility (266.7 MPa and 6.8% respectively) of the alloy significantly through fine-grain strengthening, particle dispersion strengthening and kink band strengthening. Meanwhile, the corrosion resistance of the extruded alloy is enhanced through the corrosion barrier effect of long strip LPSO phase, stable product film protection as well as the formation of uniform corrosion mode. This study proves that hot extrusion is an effective method to synergistically improve the mechanical properties and corrosion resistance of WZ alloys, which can provide a favorable reference for the preparation of high-performance medical Mg alloys.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"30 11","pages":"3141 - 3154"},"PeriodicalIF":3.3,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141059607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The microstructure observations shown that the average grain size of AM30 base alloy was 7.8 μm, which decreased to 3.5 μm in the CaO-AM30 alloy. In both alloys, Mg₁₇Al₁₂ and Al6(Mn, Fe) phases were present, and C15 ((Mg, Al)₂Ca) phases were additionally present in the CaO-AM30 alloy. Also, the average size of the Mg₁₇Al₁₂ and Al6(Mn, Fe) phases was much smaller in the CaO-AM30 alloy than those in the AM30 alloy. As a result of the smaller grains and fine evenly distributed second phases, CaO-AM30 alloy shown an improved tensile strength along with a 25% increase in the elongation. Accordingly, the CaO-AM30 alloy showed higher fatigue strength (168 MPa) than the AM30 alloy (130 MPa) after ~ 10⁷ number of cycles. Nevertheless, fatigue crack growth test revealed that the CaO-AM30 alloy has a lower threshold <i>∆K</i>_<i>th</i> value than the AM30 base alloy. Also, the calculated value for <i>m</i> (log slope of <i>da/dN</i> and <i>∆K</i>) was 13.64 for AM30 alloy, which increased to 14.15 for the CaO-AM30 alloy. The relatively higher crack propagation rate of the CaO-AM30 was most likely related to the presence of larger plastic deformation zone in it than its grain size, causing the suppression of fatigue crack closure mechanism during the unloading half of the cycle. Hence, this study suggested that the fine grains improve the strength and high-cycle fatigue properties of the Mg alloys, but adversely affect the fatigue crack propagation resistance.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"30 11","pages":"3082 - 3093"},"PeriodicalIF":3.3,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141059609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the optimal laser parameter values for CoCrFeMnNi high-entropy alloy powders using the selective laser melting (SLM) method. The layer thickness was kept constant during experimentation. 5 different laser powers and 10 varying laser scanning speeds were tested, with hatch spacing from 30 to 90%. After determining the optimal laser parameters for SLM, prismatic samples were fabricated in different build orientations (0°, 45°, and 90°), and subsequently, their structural, mechanical, tribological, and corrosion properties were compared. Melt pool morphology could not be obtained at 20—40 and 60W laser powers and at all laser scanning speeds used at these laser powers. At 100 W laser power, 600 mm/s laser scanning speed, and 70% hatch spacing parameters, an ultimate tensile stress of 550 MPa and elongation of 48% were obtained. Among the samples produced in different build orientations, the sample produced with a 0° build orientation exhibited the highest relative density (99.94%), the highest microhardness (201.2 HV_0.1), the lowest friction coefficient (0.7025), and the lowest wear and corrosion rates (0.7875 mpy).

However, the impact of shear angle on the process and mechanism remains unclear. Two channel angles, 120 and 135°, were designed for processing. The properties of the center and edge zones of the formed billets were investigated. This process is performed on AZ61 Mg alloys in the as-cast state with a processing temperature of 440 °C. The results show a significant increase in strength, with the yield strength reaching 193 MPa in the center zone of the ES-135° sample and the ultimate tensile strength reaching 241.9 MPa in the edge zone of the ES-120° sample. The increase in strength is attributed to second-phase precipitates, bimodal grain structure and high-density dislocations.

Excellent plasticity attributed to active slip system and bimodal grains. The microstructure results for the central and edge zones of the samples show that the shear angle leads to differences in the crystal orientation of the Mg alloys, and that different zones of the same sample also have different texture intensity due to the incorporation of ECAP.
