A new class of light-weight metastable high entropy alloy with high strength and large ductility
2022, MaterialiaCitation Excerpt :Recently, high entropy alloys (HEAs) have drawn great attention in the metallurgy field due to their novel properties originating from the complex interactions among the multi-principal elements in a single phase [1–3]. Especially, the face-centered cubic (FCC) HEA composed with 3d transition metals (TM) exhibits not only high strength due to the exceptional solid solution strengthening but also relatively low stacking fault energy (SFE), which results in higher strength than conventional alloys as well as better plasticity (more than 40% of maximum elongation) sometimes accompanying with twinning-induced plasticity (TWIP) or phase transformation induced plasticity (TRIP) during deformation [4–7]. However, FCC HEA has an unavoidable disadvantage compared to austenitic steel, which is relatively high density because of containing a relatively large amount of Ni and Co (5% heavier than other elements).
Orientation-dependent plastic deformation mechanisms and competition with stress-induced phase transformation in microscale NiTi
2021, Acta MaterialiaCitation Excerpt :Low magnification TEM micrographs (Fig. 4a) show a high dislocation density in the narrow deformation band, but regions of the pillar away from this band show minimal contrast. Some deformation is visible near the top surface of the pillar, which is attributed to contact with the flat punch [51,52]. A couple of Ti4Ni2O precipitates, indicated by white arrows in Fig. 4a, were observed.
