ABSTRACT:
A method of hot forming beryllium-copper alloy including from 1.60 to 2.00% by weight of Be, from 0.2 to 0.35% by weight of Co and the balance being essentially Cu, under specified conditions of a working temperature, a working rate, and an amount of work strain to produce a hot formed product of an equiaxed grain structure having a uniform stable grain size. 2
