However, conventional alloy designs by trial and error can be time-consuming and expensive. Hence, computational methods can control the stacking fault energy (SFE), which affects the mechanical properties, and develop a new CoCrWNi alloy with much lower time and cost. However, calculating the SFE requires a thorough investigation of theoretical and experimental methods due to the complicated effect between different atoms in the complex alloy system. In this study, we investigated the effect of Cu, Mn, and Fe addition on the SFE of CoCrWNi alloy using simulations (first principle and computational thermodynamics) and compared it with the experiment for the first time. The addition of Cu, Mn, and Fe to the CoCrWNi alloy increases the SFE, as demonstrated by both thermodynamic and first-principles calculation methods. The intensity of the hcp phase decreased with increasing Cu content in the CoCrWNi alloy, proving the simulation result that the SFE will increase. Furthermore, the peak analysis of X-ray diffraction using the peak shift and peak broadening method shows that the increase of Cu concentrations will reduce the deformation fault probability, twin fault probability, and stacking fault probability and then increase the SFE. Combining Cu and Mn alloying elements with the CoCrWNi alloy can be used to design a new CoCrWNi alloy that can increase the SFE to the desired value. In the present work, investigating the electronic structure, such as interlayer distance, charge density difference, and density of states, can explain the increasing SFE. This study can be helpful as a guideline for designing new CoCrWNi alloys with superior mechanical properties.</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":"31 9","pages":"2551 - 2568"},"PeriodicalIF":4.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144909853","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}

One of the key methods employed in the fabrication of aluminum foam is the space holder technique, which allows for precise control over porosity and pore size. In this study, aluminum foams with 80% porosity were fabricated using the space holder method, varying the size of the space holder particles to compare and analyze their properties. The foams were sintered using spark plasma sintering, and the resulting microstructure was examined via field emission scanning electron microscopy. The analysis confirmed the successful formation of inter-particle necking, indicating proper sintering. Additionally, micro-computed tomography was utilized to investigate the internal structure, revealing details such as pore size, cell wall thickness, and overall porosity. The results showed that both pore size and cell wall thickness decreased with smaller NaCl particle sizes. Compression tests were conducted to assess the mechanical properties of the foams. Factors such as porosity, pore size, and cell wall thickness were found to significantly influence the compressive strength. Notably, as the NaCl particle size decreased, a corresponding reduction in compressive strength was observed, likely due to the effect of reduced cell wall thickness.
