for Nonferrous Metals摘 要:The morphology and crystallography of phases in the Cu-0.12% Zr alloy were investigated by scanning electron microscope(SEM), transmission electron microscope(TEM), and high-resolution transmission electron microscope(HRTEM). The results show that the as-cast microstructure of Cu–Zr alloy is mainly Cu matrix and eutectic structure which......

of Cu–12Ag isothermal annealing, LIU et al [7] found that the strength of the alloy can reach 700 MPa when annealing at 400 °C for 0.5 h, and the strength reduced to 500 MPa or less when annealing at 400... to the influence of these elements on tensile strength, electrical conductivity, anti-softening temperature, friction and wear properties of Cu–Cr alloy. For example, SKAI et al [8] studied the effect of Sn......
