Here, the new strategies based on thixomolding process had been explored to utilize the outstanding anti-permeability of graphene nanosheets (GNPs) while inhibit its galvanic corrosion with the matrix, so as to improve the corrosion resistance of composites. The agglomerate of GNPs with 0.9 wt% content is the main reason for the deterioration of corrosion performance due to the formation of micro-galvanic corrosion. The grain refinement of composites with 0.6 wt% content had positive effects on the better corrosion resistance. After process adjusting, the unique distributions of GNPs along grain boundaries play a vital role in improving the corrosion resistance. It can be ascribed to the following mechanisms: (I) The barriers can be established between the Mg matrix and corrosive medium, hence blocking the charge transfer at the interface; (II) The GNPs can effectively promote apatite deposition on the Mg matrix, leading to form dense apatite layers and prevent the further invasion of SBF; (III) The GNPs acting as reinforcements exists in the corrosion layer and apatite layer, impede the apatite layer falling off from the Mg matrix. These findings broaden the horizon for biomedical applications in Mg matrix composites to realize desired performances.</p></div>","PeriodicalId":457,"journal":{"name":"Acta Metallurgica Sinica-English Letters","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140377358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their fatigue performance has remained unknown. In order to elucidate the fatigue behavior of DRTMCs, a tension–tension fatigue test was performed on a TiB/near <i>α</i>-Ti composite with network structure. The results showed that the variability of fatigue lifetime increased as the stress level decreased. Fractography analysis indicated that fatigue crack initiation was associated with facet formation, while the subsequent propagation was hindered by the network structure comprising TiB whiskers and silicides. Crystallographic characterization further revealed that facets formed due to a combination of shear and normal stress. The reduction in fatigue lifetime was attributed to an increase in the effective slip length, which was influenced by the orientation of grains near the crack-initiation sites toward basal slip in the life-limiting specimen. Quasi in situ observation suggested that the crack initiation was facilitated by both basal and prismatic slip of <i>α</i>-Ti as well as fracture of TiBw. Crack propagation was found to be associated with basal and prismatic slip systems with high Schmid factors, regardless of whether the crack was intergranular or intragranular.</p></div>","PeriodicalId":457,"journal":{"name":"Acta Metallurgica Sinica-English Letters","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140125351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Achieving a uniform distribution of SiC requires fine control over the parameters of SiC and the processing and preparation process. However, due to the numerous adjustable parameters, using traditional experimental methods requires a considerable amount of experimentation to obtain a uniformly distributed composite material. Therefore, this study adopts a machine learning approach to explore the tensile strength of SiC-reinforced magnesium matrix composites in the mechanical stirring casting process. By analyzing the influence of SiC parameters and processing parameters on composite material performance, we have established an effective predictive model. Furthermore, six different machine learning regression models have been developed to predict the tensile strength of SiC-reinforced magnesium matrix composites. Through validation and comparison, our models demonstrate good accuracy and reliability in predicting the tensile strength of the composite material. The research findings indicate that hot extrusion treatment, SiC content, and stirring time have a significant impact on the tensile strength.</p></div>","PeriodicalId":457,"journal":{"name":"Acta Metallurgica Sinica-English Letters","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140125357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 show that the increased specific surface area of the lattice structure leads to increased powder adhesion, making the manufacturability proportional to the unit size and volume fraction. The compressive response of the CuAlMn SMAs Gyroid TPMS lattice structure is negatively correlated with the unit size and positively correlated with the volume fraction. The superelastic recovery of all CuAlMn SMAs with Gyroid TPMS lattice structures is within 5% when the cyclic cumulative strain is set to be 10%. The lattice structure shows the maximum superelasticity when the unit size is 3.00 mm and the volume fraction is 12%, and after heating recovery, the total recovery strain increases as the volume fraction increases.
