Phase stability trends of all equiatomic alloys from Al-Cr-Fe-Hf-Mo-Nb-Ta-Ti-V-W-Zr. a Predicted BCC solid solution phase fraction of every alloy at 1300 K. Alloys above Tsolidus or with coexisting BCC solid solution phases are not shown. b Fraction of alloys that are 100% BCC solid solution at 1300, 1550, and 1800 K versus the number of elements N. The solid black line is a fit to cσN. At 1800 K, only 11 of the 165 N = 8 equiatomic alloys have solidus temperatures below 1800 K, thus this point has poor statistics, and none of the N > 8 equiatomic alloys have solidus temperatures above 1800 K, thus the sharp drop to zero.
