Development of Rolling Schedules for AZ31 Magnesium Alloy Sheets

Abstract

This report describes the effort to develop a low-temperature rolling procedure for as-received AZ31B, a magnesium (Mg) alloy that contains approximately 3% aluminum and 1% zinc. In particular, we investigated the ability to roll AZ31B to thicknesses of about 1.5 mm using conventional rolling temperatures. Next, attention was focused on reducing the rolling temperature as much as possible while still producing thin sheets (???1.5-mm thickness) with an intent to retain a fine-grained microstructure. The ability to produce such thin sheets at as low a temperature as possible represented a significant challenge, which, if solved, could enable the development of ultrahigh-strength Mg alloy sheet for subsequent processing into high-strength components. Moreover, the results of this study would then could be used to develop further rolling schedules for other more complex Mg alloys via roll processing.
