When heated, it reacts with atmospheric gases, leading to the formation of the TiO₂ oxide film on its surface. This film does not protect the material against further oxidation. To solve this problem, heat-resistant coatings, including TiAl-based ones, are applied to titanium. This study investigates ternary Ti-Al-Cr surface layers with different concentrations of components. The protective layers were fabricated on titanium substrates by non-vacuum electron beam cladding. This method provides the formation of thick coatings (up to 2 mm in a single pass of the electron beam); however, the structure of the cladding layers can be significantly inhomogeneous. To reveal the influence of microstructural features of the coatings and the uneven elemental distribution on their oxidation behavior, detailed structural studies combined with the CALPHAD method were performed both before and after oxidation testing. It was found that an Al-rich alloy consisting primarily of the γ-phase provided the best protection against oxidation. The introduction of high concentrations of both Al and Cr yielded contradictory results. Although the L1₂-and C14-phases formed in the coating are predicted to contribute to the development of a protective Al₂O₃ film, the oxidation resistance of this cladding layer was comparable to that of titanium. This result can be attributed to the inhomogeneity of the coating and the appearance of the B2-phase in local areas of the coating at oxidation temperature and the decomposition of the Cr-depleted C14-phase. Furthermore, the Cr-rich B2-phase provides better oxidation resistance than the α₂-phase of Al-lean cladding layers.</div></div>","PeriodicalId":331,"journal":{"name":"Intermetallics","volume":"181 ","pages":"Article 108745"},"PeriodicalIF":4.3,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628415","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}

A comparative analysis is conducted to elucidate the direct influence of annealing at 1373 K on their physical characteristics. Notably, significant differences in magneto-structural behavior are observed between as-prepared GCMWs and the bulk alloy. For the bulk sample, annealing promotes homogenization and a decrease in the average grain size from 24 μm to 2 μm, as confirmed by SEM and XRD analyses. In contrast, a broader grain size distribution in MnFePSi GCMWs, ranging from 0.8 μm to 40 nm compared to the as-prepared sample's with relatively uniform size of 36 nm is induced by annealing. Additionally, annealing enhances the Fe₂P phase content in both samples. The annealing process significantly affects magnetic properties of MnFePSi GCMWs. A notable reduction in coercivity (<em>H</em>_<em>c</em>) is observed, with a decrease in <em>H</em>_<em>c</em> from 761 Oe (as-prepared) to <em>H</em>_<em>c</em> = 46 Oe (annealed), as evaluated from the hysteresis (M − H) loop measured at <em>T</em> = 5 K. The as-prepared MnFePSi-GCMWs exhibit a unique metamagnetic phase transition in M − H loops measured at various temperatures (200 K–5 K). Conversely, the annealed GCMWs display a more uniform metamagnetic transition in M − H loops measured at <em>T</em> = 20 K and 5 K. Furthermore, as-prepared GCMWs exhibit multistep magnetic M − H loops below 100 K, which is absent in the annealed samples. This study underlines the substantial effect of the annealing on MnFePSi-GCMWs, enabling the tailoring of magnetic phenomena, such as metamagnetic phase transition, multistep magnetic behavior, and the control of magnetic response (hardening/softening). These tailored properties can be exploited in a wide range of applications based on glass-coated microwires.</div></div>","PeriodicalId":331,"journal":{"name":"Intermetallics","volume":"181 ","pages":"Article 108742"},"PeriodicalIF":4.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621096","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 influence of varying B₄C ceramic particle content on the microstructure evolution and mechanical properties of CoCrFeNi(B₄C)_x HEAs was systematically investigated. Microstructure analysis reveals that increasing the B₄C ceramic particles promoted the precipitation of M₇C₃ carbides at grain boundaries, resulting in a dendritic microstructure.

Furthermore, the microhardness of the M₇C₃ carbides increased from 12.1 GPa to 15.5 GPa with higher B₄C ceramic particle content, highlighting the contribution of these carbides to the overall hardness of the composite.

Through thermodynamic parameter calculations and JMatPro software simulations, it was revealed that CoCrFeNiTi_x HEAs tend to form second phases, with the FCC phase as the main phase and the presence of BCC, Laves, η, σ, and γ′ phases, significantly enhancing the alloy's strengthening effect.

The average microhardness of CoCrFeNiTi_0.3, CoCrFeNiTi_0.7, and CoCrFeNiTi_1.0 HEAs deposition layers are approximately 328 HV, 506 HV, and 660 HV, respectively, with simulated hardness values very close to the experimental results.
