Abstract

According to current development trends for automotive parts, light-weight is a key issue in improving fuel efficiency and CO2 reduction. Compared to steel and aluminum, magnesium has a relatively low specific gravity. However, it is challenging to use magnesium to produce a product at room temperature because magnesium has a hexagonal close-packed crystal structure. Therefore, the structure is not suitable for plastic deformation without using a heating system. As a result, a magnesium alloy sheet and die need to be heated from 250 to 300ºC. This paper presents the development of warm forming technology for automotive dash panel using magnesium alloy sheet.
