The results of the study were analyzed in comparison with similar parameters for an alloy of the same composition, but synthesized in a laboratory SHS plant and having a smaller mass of 0.8 ± 0.1 kg as compared to the mass of a large-sized ingot of 4.7 ± 0.1 kg. The large-sized ingot with chemical and phase compositions uniform by volume is reported to have been produced, its metal demonstrating similar kinetics and heat resistance at 1150°C (30 h) at different distances from the center. It was found that the heat resistance of the alloy decreased with ingot mass increasing from 55 ± 3 g/m2 for the laboratory ingot to 19 ± 3 g/m2 for the large ingot. The strength properties of the metal of the large ingot during compression testing were (sigma _{{text{u}}}^{{text{c}}}) = 1662 ± 10 MPa, (sigma _{{0.2}}^{{text{c}}}) = 1531 ± 25 MPa and during tensile testing σu = 293 ± 10 MPa, σ0.2 = 236 ± 5 MPa, which was practically no different from the properties of the laboratory ingot. The mechanical properties of NiA–Cr–Co-based alloys of various alloying systems synthesized by the SHS method with subsequent use of special metallurgy methods are also given.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 3","pages":"508 - 518"},"PeriodicalIF":0.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122349","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 main conditions for preparing these materials and possible technologies based on small diameters of carbon fibers and short distances between them in a beam of the order of several microns are discussed. The conclusion is made that special coatings in the form of silicon carbide and nickel on carbon fibers are needed to improve their impregnation with an aluminum matrix. The chemical deposition of nickel from a bath containing nickel chloride hexahydride, ammonium chloride, sodium hypophosphate, sodium citrate, and lead sulfide is studied. All individual fibers are covered with nickel, and this does not lead to a decrease in their strength. The use of the plasma technology for depositing an aluminum matrix on carbon fibers coated with silicon carbide and nickel is substantiated. The action of the plasma jet does not reduce the strength of the LU-2 carbon tape coated with silicon carbide. However, when aluminum is deposited on the tape with a nickel coating, softening is observed at distances of 50 and 100 mm from the plasma torch. The optimum conditions for the preservation of the strength of carbon fibers during plasma deposition of aluminum on the tapes coated with silicon carbide and nickel are determined by mechanical tests and metallographic studies.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 3","pages":"531 - 535"},"PeriodicalIF":0.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122418","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 quenched state of both steels shows the presence of three phases: α', γ, and ε. The ε-phase content decreases from initial values of 65 and 85% to 10–15 and 25–40%, respectively, for Fe–15.9Mn–0.007C and Fe–17.7Mn–0.03C steels after a reduction of 40–60%. The α'-phase content increases to 85–90 and 60–75%, respectively. Lattice strain calculations during the ε → α' and α' → ε phase transformations show preferential transformations during rolling. The texture evolution of the ε phase indicates that the Fe–15.9Mn–0.007C steel undergoes both the ε → α' transformation, causing volume expansion and compressive stresses, and the α' → ε transformation, resulting in volume contraction and tensile stresses. This explains the low level of residual stress in this steel, which varies from –100 to +100 MPa. In contrast, the Fe–17.7Mn–0.03C steel undergoes only the ε → α' transformation during cold rolling at all reductions, generating compressive stresses of 200–400 MPa due to volume expansion.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 3","pages":"603 - 610"},"PeriodicalIF":0.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122354","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}
