Effects of Temperature and Forming Speed on Square Cup Drawability of AZ31 Magnesium Alloy Sheet

Abstract:

Square cup drawing experiments were performed on an AZ31 sheet at various temperatures (T) ranging from room temperature to 200°C with three different punch travel speeds (V) of 3, 30 and 300mm/min. From the experiment, the highest drawability was observed either at T=175°C with V= 30mm/min or at T=200°C with V= 300mm/min. The effects of temperature and forming speed on the formability were discussed by comparing the result of drawing experiment with the high temperature tensile properties of the material. The forming limits were well predicted by FE simulation using a temperature and rate dependent constitutive model.
