LSP, a surface enhancement technique, was applied to address the residual stress and enhance the mechanical performance of these bimetallic components. Electron Backscatter Diffraction (EBSD) analysis post-LSP showed refined grain structures, contributing to the observed enhancements in mechanical properties. The research revealed that LSP treatment increased the tensile residual stress at the bimetallic interface from 109 ± 2.5 MPa to 185.9 ± 2.5 MPa, indicating a strengthening of the bimetallic interface. The tensile strength of the Grade 91 Steel part increased from 1140 ± 6.5 MPa to 1280 ± 4.5 MPa after LSP, while the Monel-400 section showed a slight decrease in tensile strength from 516 ± 2.5 MPa to 511 ± 6 MPa but an increase in elongation from 31 to 38.5%. Furthermore, microhardness at the interface improved, with a rise from 267 ± 3 HV0.1 to 303 ± 4 HV0.1 post-LSP. The enhanced properties of the bimetallic components are particularly beneficial for applications in the petrochemical and marine industries, where the combined resistance to thermal and corrosive environments is critical. This study provides a new understanding of the application of LSP in improving the mechanical properties of WAAM-produced bimetallic components.</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 1","pages":"36 - 48"},"PeriodicalIF":3.3,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141516956","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 effects of oxygen levels on the integrity of high pressure die casting specimens was investigated by injecting oxygen at different durations (1 s, 3 s, and 5 s) through air jet valves installed at the mold cavity. The CT results indicate that increasing the oxygen injection time significantly reduces the porosity volume from 0.9 to 0.18%, with smaller defects in size as well. Notably, after applying the PFDC process, the elongation improved from 2.23 to 4.58%, suggesting that replacing atmosphere in the cavity space with oxygen plays a crucial role in enhancing the mechanical properties of the HPDC specimens. The improvement is believed to be caused by promoting oxidation reactions with the high concentration of oxygen, which leads to a decrease in gas entrapment during the casting process.</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 12","pages":"3444 - 3457"},"PeriodicalIF":3.3,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141505006","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 increase in Cr and Mo elements in the expanse of Co increased the structure's hardness before and after the heat treatment. As this increase was 10% in as-sprayed conditions, annealing raised the increase to 30%. Splat boundaries were the most vulnerable constituents against forces, creating a significant disadvantage in terms of structural integrity and affecting the overall performance. After annealing, the boundary strengths experienced a remarkable four-fold increase and cracks and fractures reduced significantly. The susceptibility of splat boundaries had a detrimental effect on room temperature wear behavior, and increased boundary densities led to a marked reduction in wear performance.

However, designing a DSS with high wear and corrosion resistance using traditional trial-and-error methods required a significant amount of time and cost. This study proposed a material design method based on machine learning (ML) to accelerate the development of novel DSS. A composition-process-performance database for DSS was established, and four ML model such as K-Nearest Neighbor Regressor (KNR), Ridge Regression (RR), Decision Tree (DT), and Random Forest (RF) were employed to train the database. Predictions of wear and corrosion resistance for DSS were achieved. The predicted and actual values of them demonstrated good consistency. Among the four models, the RF model for microhardness and self-corrosion potential exhibited the best predictive performance with an <i>R</i><sup>2</sup> value of 0.90 and 0.87, respectively. Employing the RF model for three rounds of selection obtained three DSS compositions with high wear and corrosion resistance among 69,120 composition-process combinations, then named as 1Cr29Ni11Mo3.5N, 1Cr29Ni8Mo4.5N, and 1Cr29Ni10Mo4.5N.
