Abstract: Ultra-precision machining was carried out on a furnace cooled (FC) eutectoid Zn-Al alloy specimen using a new technology of single point diamond turning (SPDT). Microstructural changes and phase decomposition at the surface of the ultra-precision machined alloy specimen were investigated. It was found that the ultra-precision machining induced external stress resulted in decomposition of the £` phase and crystal orientation changes of the Zn-rich phases: £b and £`, at the surface of the machined FC Zn-Al alloy specimen, which were in agreement with the tensile stress induced phase transformations and crystal orientation changes in the FC Zn-Al alloy specimen.
