The reinforcing TiB2 particles in an amount of 0.5 and 1.5 wt.% were introduced through the stir-casting process. Microstructural analysis and static tensile tests were performed to evaluate the effect of reinforcing the AZ91D alloy with TiB2 nanoparticles. It was found that the addition of TiB2 nanoparticles significantly improves the mechanical properties of the AZ91D alloy. The ultimate tensile strength increases by 3% for the composite with 0.5 wt.% TiB2 and by 10% for the composite with 1.5 wt.% TiB2 compared to the unreinforced alloy. The yield strength also increases by 5% and 14% for the composites with 0.5 and 1.5 wt.% TiB2, respectively. In addition, the microhardness is significantly increased by adding TiB2. The results obtained showed that reinforcing the magnesium alloy AZ91D with TiB2 nanoparticles increases the efficiency of its use for the manufacture of massive engineering constructions.","PeriodicalId":701,"journal":{"name":"Metal Science and Heat Treatment","volume":"67 3-4","pages":"236 - 243"},"PeriodicalIF":0.5,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145371663","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}

After intercritical annealing followed by quenching and holding below Ms, the tensile strength of the steel varies from 830 to 1150 MPa with elongation in the range of 20 – 24% as in dual-phase high-ductility steels.

Particles of M23C6 precipitate after aging over the boundaries of grains and microtwins as well as inside grains on components of microstructural defects and fine particles of MC carbides. The aging lowers the strength properties of the steel. The post-aging structure of the quenched steel contains particles of a FeCrMn σ-phase, which reduces the elongation to 7% in tensile tests at room temperature to 7%. Brittle fracture components associated with the σ-phase appear on the fracture surfaces and are partially preserved at elevated test temperatures (600 – 700°C). The possibilities of adjusting the chemical composition and the treatment modes of novel low-activation austenitic steels aimed at prevention of formation of σ-phase under long-term aging in the operating temperature range (650 – 700°C) are discussed.","PeriodicalId":701,"journal":{"name":"Metal Science and Heat Treatment","volume":"67 1-2","pages":"89 - 98"},"PeriodicalIF":0.5,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832292","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}

The structure, phase composition and texture of the alloys are studied using x-rays phase analysis, scanning electron microscopy and electron backscatter diffraction after micro-indentation and tensile testing. A methodology tested on titanium alloys is used to derive a formula for calculating the temperature of transition of zirconium alloys to a single-phase β-range (the temperature of polymorphic transformation Tpt). It is shown that decrease in the hafnium content provides more developed recrystallization and decelerates the decomposition of the β-solid solution during annealing yielding different second phases (ω, α″, α). The effect of the alloying with hafnium on the textural condition of the alloys during annealing is considered. The relation between the structural and phase conditions of the alloys and their physical and mechanical properties is established and recommendations are developed on the hafnium content ensuring a balanced combination of properties.","PeriodicalId":701,"journal":{"name":"Metal Science and Heat Treatment","volume":"67 1-2","pages":"33 - 41"},"PeriodicalIF":0.5,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832285","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}
