摘要：
Effects of small addition of Zr on the microstructures and properties of as-cast Cu50Ag46−xZrxTi4 alloys were investigated by differential scanning calorimeter (DSC), x-ray diffraction, microscope, and property testings. The results show that the melting point of the Cu50Ag46Ti4 alloys does not change obviously with the addition of Zr at the melting points of about 779 °C. Adding Zr reduces the volume fraction and size of the board strips of Cu3Ti phase, promotes the uniform distribution of the new phase Cu4AgZr, and improves the Vickers hardness and shear strength of the based alloys. Moreover, increasing the Zr content can improve the high-temperature oxidation resistance of alloys.
