Abstract
Process for the formation of precipitation hardened beryllium-nickel, beryllium-iron, and beryllium-cobalt alloys and cermets for structural and bearing use respectively in precision instruments and such alloys and cermets. A beryllium-nickel, -iron, or -cobalt high solute solution at elevated temperature is rapidly cooled to provide a readily machined solid solution. After machining, the alloy is reheated to an intermediate temperature under controlled conditions where precipitation hardening occurs through limited precipitate cluster formation. A cermet is formed in the process with the addition of a ceramic material to the beryllium alloy in the initial steps.
