Effects of Titanium Refining Methods on the Microstructure and Mechanical Properties of A356-0.1%Ti Alloys
Effects of titanium refining methods on the microstructure and mechanical properties of A356 alloys were studied. The results showed that the A356 alloys refining by electrolytic low titanium Al alloys had excellent grain refinement effect and high age-hardening behavior comparing with the traditional A356 alloys. By means of DSC analyses, the solidification characteristics and the age-hardening behavior were discussed. The results showed that the E-A356 alloys had more powerful nucleation potency than that of the M-A356 alloys. The exothermic peaks of β// phase was shifted to a slightly lower temperature, and the rate of the continuous transition from GP zone to metastable phases increased.
