Study on Weld Tensile Property of Blanks Welded by Magnesium Alloy with Different Types

Welded blanks of magnesium alloy had been manufactured by gas tungsten act welding(GTAW).It had tested the mechanical properties of welded-blanks;studied the tensile properties on the direction that perpendicular to the weld,considering the differences of tensile properties between different magnesium alloys.The research respected that the sample broke at heat affect zone(HAZ) by the side of AZ31 magnesium alloy;The fracture formed by linked-toughening nests,and it was considered ductile fracture on macroscopic.
