It was found that yttrium addition could effectively control the distribution and volume fraction of B2-CuZr precipitated phase in the composites by adjusting the glass-forming ability of the alloys, and suppress the eutectoid decomposition of B2-CuZr.Within 2 at.% yttrium addition, the volume fraction of B2-CuZr precipitation in the glassy matrix decreases significantly with the increase of yttrium content. For more than 2 at.% yttrium addition, the volume fraction of B2-CuZr precipitation increases as yttrium content increases. An optimal amount of yttrium (2–3 at.%) enhances glass-forming ability of the alloy, reduces B2-CuZr precipitation, and obviously improves the agglomeration and distribution uniformity of B2-CuZr in the amorphous matrix. The compressive properties of BMG composites with more than 1 at.% yttrium addition drop considerably, which should be mainly attributed to the abundant and various forms of Y2O3 brittle phase formed in the glassy matrix.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140232536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unique porous scaffold can be introduced as a promising candidate for dental implants owing to bone-like elastic modulus of 3.5 GPa and compressive strength of 550 MPa.

By increasing TiB2 at 0.4–0.5 rpm, a complete dissolution of the equiaxed and columnar network morphologies were achieved.

After removing the surface carbide damage by electrolytic polishing, the number of sub-surface carbides increases, and the maximum content is 26.1%. After LSP, the wear resistance of the steel is improved because LSP causes a large residual compressive stress on the surface. The wear performance of the sample after removing the surface damage becomes better, which is related to the elimination of many crack sources and the larger residual compressive stress.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"34 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140242084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increase of deformation, the [Formula: see text] tension twins nucleated continuously, and there were stretching twin variants that were 60° away from the original stretching twins.

Here, we developed a strong, ductile and cost-effective duplex MEA with a chemical composition of Fe45Cr25Ni10Mn15Al4C1 (at.%) in hot-rolled state and explored the potential of strengthening this MEA by forming hard σ phase via tempering within the temperature range of 400–900°C. Severe embrittlement is observed when the MEA is tempered at between 700°C and 800°C. Microstructural characterisation reveals that σ phase with a lamellar morphology is formed via a diffusion-controlled process. The severe embrittlement results from the intrinsic brittleness of σ phase and the lamellar morphology that provides continuous paths for crack propagation.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140245831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings reveal that the corrosion resistance and hydrogen atom diffusion of X80 pipeline steel exhibit an initial decline, followed by an increase with escalating inhibitor concentration. The nadir values are recorded at an inhibitor concentration of 500 mg·L−1, attaining a remarkable maximum inhibition efficiency of 97%. Following the addition of corrosion inhibitors, the formation of corrosion products notably decreases, indicating a positive inhibition effect on both corrosion and hydrogen permeation.

It was observed that hardening is a function of not only tempering temperature and time but also of the heating rate according to the Hollomon–Jaffe parameter.

The matrix alloy is AZ91 Mg alloy which primarily consists of 9 wt-% Al and 1 wt-% Zn. A mechanical-induction stir casting process was used to add CNTs to the composite. XRD patterns and EDX analysis showed that all composites have a microstructure of α-Mg, Mg17Al12, SiC and B4C. The outcomes demonstrated that the Mg17Al12 networks can be significantly thinned by the additional CNTs. The hot extrusion also dispersed the B4C and SiC particles in the structure, improving the particle-stimulated nucleation (PSN) plus twinning mechanism, but the presence of micron particles caused stress concentration, which did not affect the composites’ strength and elongation. The wear behaviour of the as-cast and extruded composites was studied by applying 5, 10 and 20 N forces at room temperature. The results showed that the mass loss and the coefficient of friction values are decreased with the addition of CNTs, which is attributed to the increased microhardness and self-lubricating properties of the CNTs.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140248989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
