The Limiting Dome Height Tests and Formability of Magnesium Alloy Sheet AZ31B

Abstract:

The assembly of the limiting dome height tests is developed to evaluate the formability of the magnesium alloy sheet AZ31B. The influence of forming conditions on the formability of AZ31B sheet is investigated by limiting dome height tests. The limiting bulging coefficient is used to represent the formability of AZ31B sheet in the tests. The sheet thickness, forming temperature, punch speed and lubrication are taken as influence factors in the tests. The experimental results show that the sheet of thickness 0.6mm has better formability and the proper forming temperature is about 200~250°C for AZ31B sheet. The low punch speed and good lubrication can also improve the formability of AZ31B sheet.
