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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 587,533, filed November 17, 2017, the entire contents of which are incorporated herein by reference. Background technique [0003] The present disclosure relates to metal rims or metal rings for casting amorphous metals. In particular, the rings of the present disclosure are made of beryllium copper alloy. A method of making the ring is disclosed and will be described with particular reference to the ring. [0004] Beryllium-copper ("BeCu") alloy is known for its excellent combination of thermal conductivity, strength, toughness, impact energy and corrosion resistance. Other advantages of beryllium copper include relatively high electrical conductivity, ultrasonic inspectability, and good thermal management. The combination of these properties makes beryllium copper alloys ideal for a wide range of applications. However, more econo...
