The hetero-zone boundary affected region (HBAR), with a high strain gradient, plays crucial role in the synergistic deformation of layered materials. Our previous experimental study demonstrated that decreasing interfacial spacing leads to higher fraction HBAR and an enhanced combination strength ductility. In this work, conventional mechanism-based gradient (CMSG) plasticity model is adopted simulate tensile behavior Cu–Fe materials three different spacings. simulation results indicated...
AbstractA novel TiAl alloy was prepared by sintering and forging, the microstructure compression properties of sintered forged alloys were investigated. The results show that consists γ-TiAl α2-Ti3Al; in both states is divided into fine-crystal regions coarse-crystal regions, state consist slate-like γ grains with a small amount α2 grains, while equiaxed grains. few has lower porosity more homogeneous microstructure. compressive improved, strength increased from 1172 to 2349 MPa, engineering...
TiAl alloys are attractive as promising aerospace structural materials. However, their application is limited by the lack of a good combination strength and toughness. Here, novel alloy with two alternately distributed components (Ti48Al2Cr2Nb Ti45Al8Nb) successfully prepared powder metallurgy. As revealed compression test, material displays an adequate unprecedented strain, which high ~2.5 GPa ~48%, respectively. The Ti48Al2Cr2Nb region play critical role in accommodating deformation...
The microstructures and properties of powder metallurgy Ti-45Al-10Nb (at.%) alloys fabricated by vacuum hot pressing consolidation milled have been investigated. Under the sintering conditions, alloy exhibits much fine-grained microstructure, which consists a double phase γ + α2 microstructure containing Ti2AlC precipitates. Tensile are measured at 900 °C–1000 °C under strain rate 1 × 10−4 s−1. This displayed outstanding high-temperature tensile strength, with strength (UTS) 410.2 MPa...
