摘要：
Microstructural evolution and related phase transformation of an extruded eutectoid Zn-Al based alloy are studied in detail under creep deformation at 150 degrees C. Lamellar structure in the extruded alloy spheroidized partially into fine grain structure. Also decomposition of a metastable eta(T)' phase and a four phase transformation, alpha+epsilon-->T+eta, were observed in the creep deformed alloy specimens. Creep rupture of the extruded Zn-Al alloy was studied in correlating with the creep induced phase transformation and microstructural changes.
