Effect of Al-Ti-B on Microstructure of AM60B Alloy During Semi-solid Isothermal Heat Treatment
The effects of Al-Ti-B metamorphic agent on microstructure of AM60B alloy as-cast and semi-solid isothermal quenching were studied.The results show that: the microstructure evolution of the alloy in isothermal quenching process after modification treatment is faster.Disadvantageous to the grain becomes uniform rounder,the grain will deformation and bulky easily if the heating temperature in isothermal quenching process is too higher.
