Abstract
This work aims to discover the effects of ultrasonic vibration and heat pipe assistance during the friction stir welding (FSW) of AZ31 magnesium alloy. The microstructure and mechanical properties of FSWed AZ31 alloy were investigated. The ultrasonic vibration and heat pipe assistance can promote the dynamic recrystallization of AZ31 magnesium alloy during the FSW process, which reduces the inhomogeneous microstructure and the grains and weakens the texture intensity of the FSWed AZ31 alloy. The microstructure and texture of the joint are regulated by the ultrasonic vibration and heat pipe assistance, to enhance the tensile strength, elongation and microhardness.
