BERYLLIUM-COPPER, METHOD AND APPARATUS FOR PRODUCING BERYLLIUM-COPPER

摘要

A method for producing a beryllium-copper containing at least Be and Cu, which includes a solid solution step for cooling the beryllium-copper at a cooling speed at which the Be remains dissolved in the Cu, after the beryllium-copper is held for predetermined solid solution time in a solid solution temperature range which is a temperature range in which Be is dissolved into the Cu; processing step for applying plastic strain to the beryllium-copper over multiple times in a processing temperature range which is a temperature range in which the Be is not precipitated, the beryllium-copper having been cooled in the solid solution step; and age hardening step for holding the beryllium-copper for predetermined age hardening time in a precipitation temperature range which is a temperature range in which the Be is precipitated, the beryllium-copper having been received only the plastic strain in the processing step.
