Abstract: Based on the results of observation and microanalysis by scan electron microscopy(SEM) and electron probe microanalysis(EPMA),the morphologies and microconstituents of different phases in a novel high strength and wear-resisting zinc alloy(ZMJ) were determined.The results of structural determination by X-ray diffraction(XRD) and transmission electron microscopy(TEM) indicate that the crystal lattice parameters of some phases in this alloy are changed due to the solute elements.It is also found that the microhardnesses of different phases are varied in a large range.Phases containing Mn are much harder than the matrix phase and despersion of tiny hard phases in the soft matrix is the general characteristic of this novel alloy.
