Thermoelectric coupling deep drawing process of ZK60 magnesium alloys

In this work, thermal deep drawing and thermoelectric coupling tests were performed on an annealed ZK60 magnesium alloy sheet to investigate the effect of pulse current formability during process. The effects forming drawn parts studied, changes thinning rate hardness obtained. results showed that using improved increased ultimate depth drawing. value part overall increasing trend, followed by drawing, which was significantly higher than after annealing without deep-drawn had different grain sizes in places, dynamic recrystallization occurred varying degrees each region. Furthermore, degree punch fillet cylinder wall other areas.
