Abstract

The microstructural changes and phase decomposition at the surface of a ultra-precision raster milled Zn-Al based alloy were studied using optical microscopy, back-scattered electron microscopy and X-ray diffraction techniques. The phase decomposition and the related crystal orientation were examined after ultra-precision raster milling with various processing parameters. UPRM induced phase decomposition and the structural recovery were discussed in relation to the structural evolution of the chips. The effect of UPRM on the hardness of the surface of the alloy specimen was studied.
