Compared to the base material condition, electron back-scattered diffraction analysis after FSP reveals a considerable reduction in grain morphological disparity between the clad layer and the core due to the occurrence of grain refinement by continuous dynamic recrystallization. Scanning electron microscopy (SEM) analysis reveals various Si-induced precipitations, including Al (Mn, Fe) Si, within the stir zone due to the diffusion of Si from the clad layer to the core during FSP. The influence of microstructural changes on improving the mechanical properties of the bi-layer clad sheet is also examined. The surface microhardness values of the clad (~ 28.7 Hv) and core (~ 35.5 Hv) for the base material condition are found to be improved to ~ 34.7 Hv and 38.5 Hv, respectively, after FSP. Besides, the overall strength of the FSPed clad sheet increases by ~ 45% compared to the base material conditions. The microstructural homogenization and Si-induced precipitates act together to strengthen the interface in the clad material system.

The grain size of the extruded alloy decreased after ECAP and SSE. The finest grain size of 3.6 μm was obtained after 4 SSE passes. Second phase particles were refined and distributed more uniformly in the SSE-processed conditions. Electron back-scattered diffraction examinations revealed that 4 ECAP passes transforms the fiber texture of the extruded material to a shear-type texture component. However, a semi-fiber component, with the (0001) planes parallel to the pressing direction, was observed in SSE-processed samples. The corrosion resistance, analyzed via electrochemical testing in a phosphate buffered saline (PBS), was improved by ECAP and SSE processing. Despite the larger grain size of the ECAP-processed conditions, they showed higher corrosion resistances (<i>R</i>p) than those of the SSE-processed ones. This was attributed to the higher density of basal planes at the surface, vaster dynamically recrystallized regions, larger high-angle grain boundary fractions, lower second phase volume fractions, and more homogeneous grain structures.

In comparison, a much higher proportion of DRXed microstructure (~ 90%) with a coarser grain size of ~ 5.85 μm is formed in the alloy extruded with a large ratio of 16 (E16 alloy). The lower actual temperature during extrusion of the E7 alloy increases the supersaturation degree of α-Mg solid solution matrix, and induces a higher volume fraction of dynamic precipitates (β-Mg₅Gd) compared with the E16 alloy. After aging, the E7-A alloy exhibits a stronger precipitation strengthening effect with a peak-aged yield strength (YS) of 405 MPa. The YS of the E7-A alloy presents a remarkable improvement of 88 MPa compared with that of the E16-A alloy, which is mainly related to finer DRXed grains and stronger texture. In contrast, the hardness increment of the E16-A alloy is higher than that of the E7-A alloy, and the peak hardness of the E16-A alloy is comparable to that of the E7-A alloy. Although the high density of precipitates in the E16-A alloy contributes to a strong aging hardening response, the weaker precipitation strengthening effect of the E16-A alloy is mainly attributed to the activation of twinning in coarser grains with a weaker texture.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"44 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213631","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 results illustrated that the Si–B–Y co-deposited coating had a similar structure with the Si-deposited coating, both of them possessed three-layer structures: an outer layer of TiSi₂ matrix, a middle layer of TiSi, and an inner layer of Ti₅Si₄ and Ti₅Si₃ mixtures. However, numerous TiB₂ and Y₂O₃ phases formed in the superficial zones of the Si–B–Y co-deposited coating. The micro-hardness of the Si-deposited and Si–B–Y co-deposited coatings was significantly higher than that of the Ti–6Al–4V substrate, and displayed a gradual decrease tendency from the coating surface to the interior. Compared to the Si-deposited coating, the Si–B–Y co-deposited coating possessed a more compact structure and higher surface hardness, and offered better anti-wear performance for the Ti–6Al–4V substrate at 600 ℃. Worn against the GCr15 ball, the average friction coefficient of the Si–B–Y co-deposited coating (~ 0.449) were near equal to that of the Si-deposited coating (~ 0.474), but lower than that of the Ti–6Al–4V substrate (~ 0.685).

In this study, the deformation method of the Co-28Cr-6Mo alloy including hot forging and subsequent radial shear rolling was tested for the first time. For the obtained bars, the analysis of the microstructure formation and mechanical properties was carried out. The proposed method of thermomechanical processing made possible to form a duplex structure (γ-FCC + ε-HCP) in the alloy, in contrast to the hot forging at which a single-phase structure (ε-HCP) was observed. The resulting structure provided higher strength characteristics at the bar surface such as YS ∼ 715 MPa, UTS ∼ 1164 MPa due to the higher content of the ε-phase, while in the central zone these indicators were YS ∼ 492 MPa and UTS ∼ 948 MPa. The main effect of hardening after forging was grain refinement and formation of a single-phase composition (ε-HCP). While in the context of radial shear rolling, there was a reduction in grain size and an increase in the volume fraction of the deformed structure. Moreover, the plasticity almost did not change over the cross-section of the bar due to combination of structural and phase composition obtained after radial shear rolling. The results can provide the basis for development of industrial technology to produce long deformed semi-finished products for medical application.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213636","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}

Recycled glass particles from consumer goods waste were added to the electrolyte in order to investigate the impact of these particles on corrosion and wear resistance of the alloy. A comparison of glass particles from different sources (liquid crystal display (LCD) glass, borosilicate (BS) glass, and soda-lime (SL) glass) has been made. Also, the effect of different current modes, direct (D) and pulsed (P), on glass incorporation and the coatings morphology was studied. The microstructure and thickness of the produced coatings were studied through SEM–EDS analysis and XRD. The wear resistance was evaluated by dry sliding tests vs AISI 52100 bearing steel (block-on-ring contact geometry). The corrosion behavior was analyzed by potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS), and localized electrochemical characteristics were determined by scanning electrochemical microscopy (SECM). The results evidenced that the addition of glass improved the corrosion resistance of the samples due to the sealing effect on the typical pores of the PEO layer. In detail samples filled with glass particles show from EIS tests polarization resistances up to one order of magnitude higher than the untreated sample in the case of direct current mode and up to two order of magnitude higher in the case of pulsed current mode. The effect on wear resistance is instead strictly related to the type of glass as, if compared to the base PEO layer, it is improved only by selected additives with the more promising results obtained with the LCD glass in direct current mode that produce a decrease of the wear depth of around one order of magnitude in comparison with the sample PEO treated without glass addition. Globally the more promising type of glass particles, both in term of improvement of the wear and of the corrosion properties, seem to be the LCD glass particles. This fact was related to the particular chemical composition of this type of glass and in particular with the alkali-free composition of the glass.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"17 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213633","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 this research, the microstructure and texture evolution mechanism across the weld thickness and different FSW zones are studied. Cross-section of the weld joints developed by UwFSW and C-AFSW were investigated via transmission electron microscopy (TEM) and electron backscattered diffraction (EBSD). EBSD data of C-AFSW joints reveal that significant grain refinement occurs in the stirred zone (SZ) due to continuous dynamic recrystallization. As compared to C-AFSW, the microstructural evolution mechanism in UwFSW was found to be very complex in the different parts of the SZ. For UwFSW, discontinuous dynamic recrystallization and geometric dynamic recrystallization were found to be the main microstructural evolution mechanism in the SZ. In addition, the enhanced cooling rates of UwFSW produce a fine grain structure and a large number of high angle boundaries (HABs). Both C-AFSW and UwFSW showed mixed grain structure in the thermomechanically affected zone. TEM results showed dislocation accumulation and annihilation were predominant in UwFSW with fine and denser rod-shaped (θ́-Al₂Cu) precipitates.
