In this study, a high-temperature titanium alloy, Ti-6.5Al-3.5Mo-1.5Zr-0.3Si, was prepared under different HIP temperatures (880–1000 °C), and the microstructural evolution and mechanical properties were systematically investigated. The results demonstrated that the HIPed alloys were predominantly composed of more than 80 vol.% α phase and a small amount of β phase, and their phase compositions were basically unaffected by the HIP temperatures. Under the typical single-temperature-maintained HIP (STM-HIP) regime, the microstructure of alloy significantly coarsened as the HIP temperature increased, and the alloy strength exhibited an obvious linear negative correlation with the HIP temperature. On the basis of Hall–Petch relation, the prediction model of grain size was established, and the mathematical equation between HIP temperature and grain size (left( {d = Mleft( {T_{{{text{HIP}}}} - N} right)^{ - 2} } right)) was deduced. Furthermore, a possible evolution mechanism of microstructure was proposed, which could be divided into the decomposition of initial α′ martensite for as-received powder, formation of the globular α grains in prior particle boundaries (PPBs) region, and precipitation of the platelet α grains in non-PPBs region. For these alloys prepared by the dual-temperature-maintained HIP (DTM-HIP) regime, although their tensile properties were comparable to that of alloy prepared by STM-HIP regime with same high-temperature holding stage, higher proportion of globular α grains occurred due to more recrystallization nucleation during the low-temperature holding stage, which probably provided a solution for improving the dynamic service performance of HIPed alloys.</div>","PeriodicalId":457,"journal":{"name":"Acta Metallurgica Sinica-English Letters","volume":"38 4","pages":"627 - 641"},"PeriodicalIF":2.9,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830773","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}

Herein, the effect of annealing temperature on the high-temperature oxidation and corrosion behavior of Fe–Mn–Cr–Al–Cu–C TWIP steel is investigated. The results show that increasing the annealing temperature from 700 °C to 1100 °C reduced the mass gain of the TWIP steel oxidized at 800 °C for 8 h from 1.93 to 0.58 mg·cm−2.

The reduction in grain boundaries and dislocation density in the TWIP steel attributed to the increase in annealing temperature inhibits short-circuit diffusion, local galvanic corrosion and pitting, ultimately improving both oxidation and corrosion resistance. Moreover, high-temperature annealing prevents the formation of carbon-rich compounds and ensures uniform element distribution. The accumulation of Cu and Cu-rich products formed at the interface further protects against Cl− erosion, inhibiting pitting and local corrosion, thus enhancing the corrosion resistance of the TWIP steel.</div>","PeriodicalId":457,"journal":{"name":"Acta Metallurgica Sinica-English Letters","volume":"38 4","pages":"642 - 656"},"PeriodicalIF":2.9,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830774","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}

However, the effect of complexions features (e.g., crystalline orientation, crystalline structure and amorphous composition) on the plastic deformation remains inadequately investigated, and the correlation with the plastic transmission and mechanical response has not been fully established. Here, using atomistic simulations, we elucidate the different complexions-dominated plastic transmission and mechanical response. Complexions can alter the preferred slip system of dislocation nucleation, depending on the Schmid factor and interface structure. After nucleation, the dislocation density exhibits an inverse correlation with the stress magnitude, because the number of dislocations influences the initiation of plastic deformation and determines the stress release. For crystalline complexions with different structures and orientations, the ability of dislocation transmission is mainly dependent on the continuity of the slip system. The plastic transmission can easily proceed and exhibits relatively low flow stress when the slip system is well-aligned. In the case of amorphous complexions with different compositions, compositional variations impact the atomic percentage of shear transformation zones after loading, resulting in different magnitudes of plastic deformation. When smaller plastic deformation is produced, less stress can be released contributing to higher flow stress. These findings reveal the role of the complexions on plasticity behavior and provide valuable insights for the design of nanolayered composites.</div>","PeriodicalId":457,"journal":{"name":"Acta Metallurgica Sinica-English Letters","volume":"38 4","pages":"597 - 613"},"PeriodicalIF":2.9,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830762","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}

In this study, we employed first-principles calculations based on density functional theory to investigate the failure mechanisms at the CoSb3/Ni interface. Our findings reveal that the CoSb3(100)/Ni(100) and CoSb3(100)/Ni(111)_1 configurations are favorable interface structures. The ideal tensile strength of the CoSb3/Ni interface is markedly lower than that of bulk CoSb3, which can be attributed to structural rearrangements near the interface that weaken the strength of the Co–Sb bonds. Interface failure occurs in CoSb3, where covalent Sb–Sb bonds exhibit a tendency to soften prior to the ionic Co–Sb bonds due to their comparatively lower rigidity. Consequently, the breakage of the Co–Sb bonds leads to interface failure. Structural failure at both single-layer Sb_CoSb3(100)/Ni(100) and single-layer Sb_CoSb3(100)/Ni(111)_1 interfaces results from ruptures in intermediate Co–Sb bonds in CoSb3, whereas failures at double-layer Sb_CoSb3(100)/Ni(100) and double-layer Sb_CoSb3(100)/Ni(111)_1 interfaces stem from fractures in the uppermost Co–Sb bonds. This behavior is primarily driven by atomic rearrangements near the single-layer Sb_CoSb3 interface, which promote bond formation between Sb–Ni and Co–Ni, thereby enhancing stability within the superstructure of CoSb3.
