Effect of cold forging on Charpy impact fracture characteristics of 6N01 aluminum alloy

Abstract

By changing cut off position, forging rate and test temperature of the test piece, instrumented Charpy impact test of the 6N01 aluminum alloy was done. (1) The crack propagation energy against temperature rise depended on the maximum load. (2) The crack propagation energy against forging rate is dependent on the maximum displacement.
