The mechanical vibration was applied to the ZL101 Aaluminum alloy produced by the expendable pattern shell casting to understand the effects of pouring temperature and mechanical vibration on the microstructure and mechanical properties.The results show that without mechanical vibration

the microstructure of the ZL101 Aaluminum alloy exhibits coarse with low mechanical properties.With the mechanical vibration

the microstructure and mechanical properties of aluminum alloy can be improved greatly.With increasing in pouring temperature

the microstructure of the ZL101 Aaluminum alloy can be improved greatly

however

an too high pouring temperature can result in the coarseness of the microstructure.Moreover

the tensile strength

yield strength

elongation and hardness of the ZL101 Aaluminum alloy can be decreased to some extent with increasing in pouring temperature

and an too high pouring temperature can weaken sharply the mechanical properties of the ZL101 A aluminum alloy.Therefore

the mechanical vibration has an optimal effect on the microstructure and mechanical properties of the ZL101 Aaluminum alloy by choosing an appropriate pouring temperature during the expendable pattern shell casting.
