The status of mechanical properties of W, Mo. Ta. and Nb-base alloys as of April 1960 is discussed. Basic metallurgical considerations with respect to high temperature strength. ductility, and transition temperature are covered. The mechanical properties at elevated temperatures attainable by both artificial dispersoid systems and regular alloy systems are presented and discussed from the standpoint of dispersion, solid solution, and strain hardening. On the basis of elevated temperature strength, the order of decreasing superiority is W, Mo, Ta, and Nb-base alloys; whereas on the basis of strength-weight ratio. this order is Mo, W, Nb, and Ta-base alloys.
