Long range ordered alloys modified by group IV-B metals

摘要

Ductile long range ordered alloys having high critical ordering temperatures exist in the (V,M)(Fe,Ni,Co)3 system having the composition comprising by weight 20.6%-22.6% V, 14-50% Fe, 0-64% Co, and 0-40% Ni, and 0.4-1.4% M, where M is a metal selected from the group consisting of Ti, Zr, Hf, and their mixtures. These modified alloys have an electron density no greater than 8.00 and exhibit marked increases at elevated temperature in ductility and other mechanical properties over previously known ordered alloys.
