Ab initio phase stabilities and mechanical properties of multicomponent alloys: A comprehensive review for high entropy alloys and compositionally complex alloys (2019, background): “Overall, a wide range of alloys has been investigated, mostly fcc Co–Cr–Fe–Mn–Ni base alloys [69,70,101,103,144,145,187,188,194 ,197,201,204] as well as bcc refractory alloys such as Hf–Nb–Ti–V–Zr base ones [69,102,121,189-193,195,196,199,200,202,203,205].”
Lattice distortion in a strong and ductile refractory high-entropy alloy (2018, methodology): “In the consideration of the ductility feature of the presently-studied BCC alloy, it is likely that a mixture of edge and screw dislocations is present, and thus, the b was determined to be 9 [13,74].”
Development and exploration of refractory high entropy alloys—A review (2018, methodology): “Nevertheless, with some modifications, it has recently been successfully applied to CCAs/HEAs.(8,75,96) The first SSS model for RHEAs was proposed in 2011 by Senkov et al.”
Mechanistic origin of high strength in refractory BCC high entropy alloys up to 1900K (2019, background): “ength is comparable to the screw strength. Other evidence for the role of the edge dislocation in the strengths of BCC HEAs also exists. Yield strengths have been correlated with solute misﬁt volumes [21, 22]; this is a hallmark of edgedominated strengthening. Furthermore, ﬁrst-principles and intera”
Short communication: ‘Low activation, refractory, high entropy alloys for nuclear applications’ (2019, background): “Alloys of the NbTaV - (Ti, W, Mo) system, that have a disordered BCC structure, have been proposed as high temperature materials that offer high strength, ductility and oxidation resistance [15,16].”
