In this study, (Co1.5FeNi)88.5Ti6Al4R1.5 (R = Hf, W, Nb, Ta, Mo, V) high entropy alloys were fabricated by vacuum arc melting, followed cold rolling and aging treatment. The effects of refractory elements on the phase structure, microstructure mechanical properties (HEAs) systematically studied means XRD, SEM TEM. results show that composition all is face-centered-cubic (FCC) + L12 dual-phase addition has not changed structure alloys. tensile yield strength elongation matrix HEA are 750 MPa...
Generally, additively manufactured (AM) full martensitic titanium alloys (hexagonal-close-packed α' phase) exhibits high yield strength (>1GPa) but poor elongation to failure (<8% usually). However, this only α'-phase microstructure is not intrinsically brittle and ductility under certain process conditions. Therefore, it crucial unravel the mechanism of fluctuation for control. Here, we found less martensite-colony microstructures (LMCM) could effectively distribute stress variant...
In this paper, the effect of annealing temperature on organization and mechanical properties Al15Ti35V20Nb15Zr15 lightweight high-entropy alloy is systematically studied. The results show that consists BCC+HCP dual-phase, with increase temperature, HCP phase in increases along grain boundaries needle-like precipitates. mainly dendritic structure, promotes refinement dendrites, which reduces size from 227.21 μm to 88.28 μm, effectively improves strength, hardness, wear-resistant alloy. With...
Ultrafine W–10 wt.%Cu powders synthesized by thermo-chemical method have a good sinterability compared with the mechanically mixed powers, which are suitable for powder injection molding (PIM). The deagglomeration, however, is necessary to improve flowability of ultrafine obtain PIM feedstock high loading. Jet milling (JM) was employed in this study reduce strong agglomerations among particles, were subsequently used PIM. Results showed that JM proper process modify mass production...
Using plasma solid-state surface metallurgy is a new method for preparing high-entropy alloy (HEA) coatings. In this paper, based on the experience in and HEA, TiCoCrNiWMo HEA coatings with metallurgical bonding gradient structure were prepared by five-element co-infiltration of Co–Cr–Ni–W–Mo TC4 substrate first time. The tissue morphology evolution properties at different holding temperatures investigated. results show that coating temperature 1000 °C consists deposited layer + diffusion...
