DIFFERENTIAL SCANNING CALORIMETRY AND X-RAY DIFFRACTION STUDIES ON AGING BEHAVIOR OF Zn-Al ALLOYS

1. IntroductionZinc-based Al alloys have been widely used in metallurgical, mechanical, mineral andother industry due to their excellent castability, wear and friction .esistancell]. The remarkable success has been gained in substituting for Al alloys as wear and friction alloy.However, one of the shortage for Zn-Al alloys is their poor structure stability, which meansthat the transformation would occur when working so that as-cast alloy would not be usedin harsh working condition. The suita…
