Abstract

In thixoforming, the globule size is determined by the hoding time of last reheating stage. In this study, some experiments to investigate the relationship between the mechanical properties and the holding time were performed A357, A390 and A3l9 alloys are used in this study. This paper shows the evolution of the microstructure according to the holding time of last reheating stage. Tensile test was performed for each reheating condition to examine the effect of globule size.
