Abstract
Processes are disclosed for forming beryllium-copper metal rings having a fine and uniform grain structure. A raw BeCu casting is pre-forged and turned to form a BeCu billet. The BeCu billet is subjected to various heat treatment and cooling cycles to obtain/maintain combinations of advantageous material properties. Generally, the BeCu billet is preheated, hot worked via forging, heated again, hot worked again via ring rolling followed by air cooling, solution annealed followed by quenching, and heated a final time followed by air cooling.
