Effect of Aging Treatment on Microstructure and Properties of Cu-3Si-2Ni Alloy

Abstract:

Article Preview

Effect of different aging treatment on microstructure and properties of Cu-3Si-2Ni alloy was studied by measurements at room temperature tensile properties, XRD and fracture analysis. The results show that the strengthening phase particles are precipitated along grain boundaries and inside grains after aging treatment of Cu-3Si-2Ni alloy, which benefits the yield and tensile strength at room temperature except for the elongation. In addition, the fracture surface shows that mixed ductile and brittle features, while as-soluted Cu-3Si-2Ni alloy presents the typical ductile fracture. The appropriate aging treatment is 450°C×2h after care experiments in this paper.
