摘要：

Microstructure and mechanical properties of ZK60 alloy sheets were investigated under solution treatment and artificial aging conditions. Solution treatment at 375 degrees C for 3 h and subsequent artificial aging treatment at 175 degrees C for 10 h can be considered to be the optimum T6 treatment. The uniformity of tensile properties was improved and fine equiaxed structure was obtained at this optimum T6 treatment condition. The distribution of Zn and Zr elements was also observed by transmission electron microscope (TEM). Zn can be found in rod-like beta'(1) precipitates and disc-shaped beta'(2) precipitates. Zr was found in disc-shaped beta'(2) or irregular shaped particles, but Zr was not found in the rod-like beta'(1) precipitates. (C) 2008 Elsevier B.V. All rights reserved.
