摘要	This paper investigated the influence of the microstructure on the mechanical properties of the forged ZK60-Y alloy under different heat treatments (T(4), T(5) and T(6)). The results show that the alloy at the direct artificial ageing treatment has superior strength and plasticity. X-ray analysis, SEM fracture observation and EDAX spectrum analysis reveal that bulk w-Mg(3)YZn(3) and coarsened rod-like MgZn'(beta(1)',) phases have great influence on the tensile properties of the alloy. Further investigations of the alloy aged at 180 degrees C, 200 degrees C and 225 degrees C for 0.5-100 h, respectively, suggest that the mechanical properties and the fracture characteristics are closely related with the variation of the rod-like beta(1)', precipitation. The fracture observation of the samples aged at 200 degrees C indicates that with the increase of the density and the size of the rod-like beta(1)', precipitation, more semi-cleavage planes will appear on the fracture surfaces.
