Microstructure and Properties of a Bismuth-Brass

Article Preview

Abstract:

The Cu-40wt%Zn-1.0wt%Bi-1.0wt%Mn bismuth-brass was prepared by casting and annealing. The microstructure was investigated by scanning electron microscopy (SEM), the phase composition was analyzed by X-ray diffraction (XRD), and the properties of mechanics and cutting were tested, too. The results show that the bismuth-rich phase is mainly distributed in the grain boundary as the shape of granules, which lead to the mechanics property and cutting property of bismuth-brass can basically reach the requirements of replace the traditional cutting-free brasses.
