The heat treatment process of the coating was carried out to explore the effect of the heat treatment process on the microstructure and corrosion resistance of the coating. The results indicated that the porosity of the coating increases slightly with an increase in nickel powder content. The metal nickel plays an anodic protection role in the Cu/Ni battery. However, too much nickel will lead to too much anode material, and the overall structure of the coating will be destroyed after anode corrosion. The composite coating prepared with 40 wt% nickel powder has the best corrosion resistance. After heat treatment, the corrosion resistance of copper/nickel composite coatings is reduced, and the quality of the coatings is improved.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"164 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prediction for the response variable FD was obtained with the help of empirical relation between the response and the input variables using RSM’s (RSM) Box–Behnken design of experimental technique and also through Neural Network (NN). Predicted values of the response by both the techniques, i.e., RSM and NN were compared with the experimental values and their closeness with the experimental values was determined. Moreover, it has been discovered that the aspect ratio has minimal impact on densification and that the FD of the preform rises with both the load applied and the initial preform density of the sintered preforms.

Through compositional optimization, Al87.5Ti6.25Hf6.25 (at%) was chosen as the experimental alloy composition. Using the Differential scanning calorimetry (DSC) and CALPHAD-derived melting point data, the as-cast alloy was subjected to 24 h homogenization heat treatment at 475 °C to achieve equilibrium. X-ray diffraction (XRD), Scanning electron microscopy (SEM), and DSC analyses revealed that the developed alloy has a dual-phase microstructure, composed of approximately 50 vol% of an FCC Al-rich matrix and 50 vol% of an Al3(Ti, Hf)-type (D022) phase, which matches closely with the thermodynamic calculations. The experimental onset melting point of the Al-rich matrix was determined to be 638 °C which is significantly higher than Al–Si-based high-temperature (HT) alloys, indicating the potential of the developed alloy as a HT structural material. Nanoindentation (NI) tests demonstrated the remarkable phase-specific nanomechanical properties of the alloy. The developed alloy possessed a microhardness of 3075 MPa, which not only surpasses 7075-Al, A390-Al alloys and CP-Ti, but also rivals the microhardness of Ti–6Al–4V alloy at nearly 18% lower density. The study highlights the potential of this novel alloy in applications that demand for materials with low density, high hardness, and superior wear resistance.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"43 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141785162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the limitations of DMLS is the reusability/ recyclability of the process consumables (waste metallic powder). In the past, some studies testified to the reusability of waste metallic powder of DMLS to support a circular economy. But hitherto little has been reported on investigations of recycled DMLS powder collected in mixed form (comprising more than one metallic alloy). This study highlights the investigations performed on mixed bio-compatible metallic powder (90% of 17–4 precipitate hardened stainless steel and 10% of Ti-6Al-4 V) collected (as waste) from the institute laboratory. During the pilot run, the samples were 3D printed on DMLS at different energy densities (ED) (66.66, 71.42, 90.67 J/mm3) selected based on the combination of available input parameters (i.e., laser power (LP), scanning speed (SCS), hatch distance (HD), layer thickness (LT), etc.), but all samples failed while printing. For successful 3D printing, the collected waste powder was preprocessed for thermal treatment (leading to chemical decomposition) at two different temperatures (550 °C (below recrystallization temperature) and 800 °C (above recrystallization temperature)). The preprocessed mixed powder at 550 °C was successfully 3D printed with ED 71.42 J/mm3 (attained with LP 120W, SCS 800 mm/s, HD 70 µm, LT 30 µm). The printed samples resulted in Young’s modulus (E) of 4155 MPa (in tensile) and 211 MPa (in flexural) along with a surface hardness of 335.9 HV at 50N. The in vitro studies outlined a corrosion rate of 0.000411 mm/year for a mixed powder-based functional prototype. Also, the specific wear rate was observed as 0.000036mm3/NM. The outcomes are also braced by scanning electron microscopy and energy dispersive spectroscopy (EDS) analysis.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"16 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tensile strengths of as-rolled specimens were increased depending on the higher volume percentage of martensite at lower roll passes. The size and distribution of martensite/austenite formations directly contribute to toughness rather than tensile strength, and the coarser martensite/austenite islands give rise to differences between actual and software predicted tensile strengths. It was revealed that fracture surfaces of as-rolled specimens were influenced by the rolling pass number changes. Spherical chromium (Cr) and molybdenum (Mo)-rich precipitates were formed more intensively in samples produced with 4 roll passes compared to 5 and 6 roll passes. Finer carbide formations and smaller dimples were found in heat-treated specimens compared to as-rolled ones. Furthermore, the positive contribution of initial martensite microstructure to mechanical properties was observed in heat-treated specimens.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"20 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ti–5Al–2.5Sn composite samples were produced using five distinct weight percentages of tungsten particles (0.5%, 1.0%, 1.5%, 2.0%, and 2.5%) reinforcement through the microwave sintering technique. Five ASTM standard test samples were subjected to fatigue tests along with field emission scanning electron microscope (FE-SEM) analysis to examine the impact of tungsten reinforcement in a titanium alloy matrix. Analysis of crack propagation and failure study was conducted using finite element analysis (FEA) software. The experiment and FEA simulation results indicate that 0.5 wt% of tungsten-reinforced matrix (Ti–5Al–2.5Sn) composites show significant improvement in fatigue performance. Crack initiation begins in the matrix region due to cyclic stress, and the particle-breaking mechanism occurs under heavy loading conditions and was examined using FE-SEM. The results revealed that Ti–3Al–2.5Sn–2W composites acquire experimental fatigue strength of 384 MPa and 406 MPa which is 3.92% and 1% higher than that of the Ti–5Al–2.5Sn matrix.
