Study on Thixo-forging of AZ61 Wrought Magnesium Alloy

摘要

The semi-solid AZ61 wrought magnesium alloy was fabricated by mechanical stirring method, Thixo-forging set-up were designed and made,. The traditional forging and thixo-forging processes of AZ61 magnesium alloy were studied with both computer numerical simulation and experimental methods,. The constitutive model of semi-solid AZ61 alloy was established in oui prior literature. The differences between traditional forging and thixo-forging processes were analyzed,. Results indicated that smaller load and uniform strain & stress were acquired in thixo-extrusion process Simulation results were good agreement with experimental ones.
