Abstract

Thermomechanical treatment of CuBe2 alloy was performed as follows: quenching, primary ageing, cold rolling and secondary ageing at different temperatures. The cold rolling was carried out following two deformation schedules (with different intensity of deformation). The investigation results on influence of deformation intensity and secondary ageing temperature on hardness, electrical conductivity, structure and activation energy on thermomechanically treated CuBe2 alloy are presented.

It was found that the deformation intensity had the greatest influence on hardness upon secondary ageing at 270°C. A hardness of 470 HV was attained by use of higher deformation intensity schedule while a hardness of 390 HV was attained with lower deformation intensity schedule.
