Simultaneous enhancement of electrical conductivities and mechanical properties in Cu-Ti alloy by hydrogenation process

Abstract

Effects of hydrogenation process of the microstructure, electrical conductivity and mechanical properties for the Cu-(1∼3) mass%Ti alloys were investigated. During hydrogenation process at 350°C, 7.5 MPa for 48 h, the disproportionation reaction occurred with forming of Ti hydrides in the alloy. It is found that remarkable simultaneous improvements of mechanical strength of 1094 MPa and electrical properties of 21%IACS are obtained in the hydrogenated Cu-3mass%Ti alloy. © (2010) Trans Tech Publications.
