A METHOD FOR MANUFACTURING COPPER LINER WITH HOMOGENEOUS AND FINE MICRO-STRUCTURE

摘要

PURPOSE: A method for producing a copper liner having homogeneous ultrafine particles is provided to homogeneously and minutely produce ultrafine particles having 20-30 micrometers using a new forging process. CONSTITUTION: A method for producing a copper liner having homogeneous ultrafine particles is as follows. An extrusion material is produced by extruding a copper billet. A forged material is produced by cold-forging the extrusion material. The forged material is re-crystallized.
