Notes:
The influence of Al-10.5%Sr master alloy, which is much cheaper than Mg-Sr masteralloys, on the as-cast microstructure of the AZ31 alloy was investigated. The research results revealedthat the Al-10.5%Sr master alloy produced obvious modification of the as-cast microstructure of theAZ31 alloy, and the modification efficiency increased with the holding time from 0min to 60min andthe amount of Sr from 0.01% to 0.1%. Moreover, the results also showed that the Al-10.5%Sr masteralloys of different states had different modification efficiency on the as-cast microstructure of theAZ31 alloy. The Al-10.5%Sr master alloys in extrusion deformation state and rapid solidificationstate had better modification efficiency than the Al-10.5%Sr master alloys received and in heattreatment state, which could be related to the microstructure of the Al-10.5%Sr master alloys withdifferent states
