Vickers hardness tests show that the Hf addition increases the hardness of Mo–Si–B–Hf alloys. The oxidation experiments were conducted at 800 °C and 1100 °C for 12 h; the detailed analysis revealed that the formation of HfSiO4 in Mo–12Si–12B–10Hf alloy can effectively decrease the content of oxygen and make the surface of the oxide layer more complete at 800 °C. At 1100°C, the distinct difference in the expansion coefficient among the oxide films results in the formation of cracks and holes in Mo–12Si–12B–10Hf alloy, so the Mo–12Si–12B–10Hf alloy shows poor oxidation resistance.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"58 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141799042","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}

As a consequence, an enhanced microstructure and a more refined grain size are achieved. The study compares the microstructure, phase composition, and mechanical properties of as-deposited and as-annealed TC4 alloys via various oscillation paths. The results show that the microstructure of the deposited TC4 alloys under the four oscillation paths is primarily acicular and cluster martensitic. Additionally, the plasticity of the specimens in the annealed state displays an overall improvement, except for linear oscillation, which experiences a decrease in overall yield strength and ultimate tensile strength. This can be attributed to the sub-stable α’ phase undergoing coarsening during annealing and eventually decomposing into (α + β) phase tissue. The β phase, with a BCC structure and more slip systems, has a lower tensile strength but greater plasticity.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"47 50","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141799822","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}

Therefore, researchers have focused on how the addition of rare earth (RE) elements to Mg alloys and the modification methods affect their tribological behaviour. This overview reflects the research on the wear of Mg alloys. Several treatments and modification methods have been utilised to improve the wear behaviour of Mg alloys, including cryogenic treatment, deep cryogenic treatment, precipitation hardening, surface mechanical attrition treatment (SMAT) and laser surface melting. Accordingly, except for SMAT, the other processes positively affected the wear resistance. Therefore, adding RE elements to Mg alloys and applying modification processes improve the wear resistance, especially at high temperatures.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"61 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141798780","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}

Microstructure analysis shows the formation of a columnar structure of IMCs at the weld zone, including Ti2Cu, TiCu, Ti3Cu4, Ti2Cu3, and TiCu3. Tensile and three-point bending tests were carried out to investigate the effects of IMCs formed by welding on the mechanical properties.

The NiO electrode showed an impressive capacitance retention rate of approximately 98% over 300 cycles.
