A modified phase transformation kinetics formula and constitutive equation are introduced. Based on the ‘phase − thermal − mechanical’ coupling theory and multi-scale simulation methods, a diffusion − temperature − phase − stress − strain − hardness multi-field coupling model is established. The multi-scale and full-process \"visualization\" prediction of carburizing and quenching heat treatment under phenomenological phase transformation kinetics has been carried out. The results show that, under the H2 process, the surface carbon content is 0.763%, the residual austenite volume at the surface is 7.7%, the residual compressive stress is 513 MPa, the maximum deformation is 40 μm, the surface hardness is 696 HV, and the carburized layer depth is 1.02 mm. The prediction errors are 1.7%, 9%, 2.1%, 7.5%, 0.14%, and 2.9%, respectively. This confirms the feasibility of the multi-field coupling model. The study analyzes the mechanisms of carburizing diffusion kinetics, iron − carbon phase transformation, and carbide precipitation, revealing the effect of process parameters on microstructure and distortion. It also discusses the impact of surface integrity on gear fatigue contact life, offering new insights for optimizing carburizing heat treatment processes and enhancing macroscopic mechanical properties.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 11","pages":"8137 - 8154"},"PeriodicalIF":2.3,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327560","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}

Five alloys commonly produced by additive manufacturing, Ti6Al4V, Ahead CP1, AlSi10Mg, Ni625, and Ni718, were used to print tensile bars using laser powder bed fusion (L-PBF). The tensile bars were then tested using the ‘gold standard’ of mechanical testing, conventional tensile methods outlined in ASTM E8. The tested tensile specimens were then sectioned through the grip section and polished using standard metallographic preparation techniques and PIP tested. When comparing the two test methods, the average tensile strength between all the materials showed a difference of 3.2% while the yield strength differed by 3.7%. These small differences between testing methods demonstrate that PIP testing is a viable alternative to the tensile test. Particular attention was given to the variation in the PIP-determined properties, and the origins of this variation are discussed. A test method standard is currently being developed for this methodology through the ASTM F42 committee, and therefore independent data to assess the precision and accuracy of the method are required.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 11","pages":"8426 - 8432"},"PeriodicalIF":2.3,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327634","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}
