Description

Some aspects of the deformation of Cu, Cu-2 w/o Al, and Cu-4 w/o Al alloy samples after thermal charging with hydrogen at 1000ºC and rapid quenching (to -150ºC isopentane) were treated in an earlier publication [1]. Comparisons were made with samples treated as just described except for use of an Ar atmosphere at 1000°C. The main experimental measurements then as now were of the Doppler broadening of the positron annihilation spectrum and the microhardness. The deformation was imposed by a Brinell indentation of 500 kgf.
