“…Moreover, the content ratio of V to Zr elements in FDR regions is approximately 1.799, and the Zr content in FID regions is as high as 80.61%. According to the present XRD results and the findings in a previous study [ 47 ], it can be deduced that the RHEAs could have V 2 Zr Laves phase and Zr-rich HCP phase in addition to the main BCC phase. Therefore, the BCC phase was mainly concentrated in the DR region, while the Laves and Zr-rich HCP phases were mainly concentrated in the ID region.…”

In this work, novel high-strength, low-activation Wx(TaVZr)100−x (x = 5, 10, 15, 20, 25) refractory high entropy alloys (RHEAs) were prepared by vacuum arc melting. Their microstructure, compressive mechanical properties, hardness, and fracture morphology were investigated and analyzed. The results show that the RHEAs possess a disordered BCC phase, ordered Laves phase, and Zr-rich HCP phase. Their dendrite structures were observed, and the distribution of dendrites became gradually more dense with an increase in W content. The RHEAs demonstrate high strength and hardness, with these properties being higher than in most reported tungsten-containing RHEAs. For example, the typical W20(TaVZr)80 RHEA has a yield strength of 1985 MPa and a hardness of 636 HV, respectively. The improvement in terms of strength and hardness are mainly due to solid solution strengthening and the increase in dendritic regions. During compression, with the increase in the applied load, the fracture behavior of RHEAs changed from initial intergranular fractures to a mixed mode combining both intergranular and transgranular fractures.

“…Recently, there has been a growing focus on highentropy alloys (HEAs) or multi-principal-element alloys (MPEAs), representing a novel class of metallic materials. This emerging field of research is attracting considerable attention within the metallic materials community [1][2][3][4][5]. Latest studies have highlighted that certain HEAs demonstrate superior resistance to irradiation when compared to conventional alloys.…”

Among new prospective materials multi-principal element alloys (MPEA) have attracted considerable attention in recent years due to their excellent corrosion and irradiation resistance as well as their good mechanical properties over a wide temperature range. The new lightweight multi-principal element titanium-based alloy 61Ti-10Cr-7Al11V-11Nb (at. %) with high ductility at room and elevated temperatures is studied. This single-phase bcc alloy was irradiated with 1.4 MeV Ar ions at room temperature and mid-range doses from 1 to 10 displacements per atom. The effect of irradiation is studied by examining the hardening. A comparison was performed with irradiation-induced hardening behaviour of MPEA, 316 austenitic stainless steel irradiated under an identical condition. It was shown that hardness increases with irradiation dose for all the materials studied, but this increase is lower in multi-principal element alloys both face-centered cubic (FCC) and body-centered cubic (BCC) structures than in stainless conventional steel.
