Influence of alloying on the anneal hardening effect in sintered copper alloys

摘要

Copper and copper alloys were prepared by a powder metallurgical method. Sintered copper and copper alloys were subjected to cold rolling with different degrees of deformation.The alloy in the cold-rolled state was isochronally annealed up to the recrystallization temperature during which the hardness was measured.These investigations show that anneal hardening effect occurs in a temperature range of 473-673 K.
