摘要：

Effects of hydrogenation process of the microstructure, electrical conductivity and mechanical properties for the Cu-(1 similar to 3) mass%Ti alloys were investigated. During hydrogenation process at 350 degrees 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.
