Evaluation of Textural Effect on the Rollability of AZ31 Alloys by Wedge-Shaped Sample Design

This paper aims to compare the textural effect on the rollability of Mg alloy sheets at different temperatures. Wedge-shaped AZ31 alloy plates with two kinds of initial textures are designed and rolled at five different temperatures. Then, the rollability under different conditions can be evaluated by observing the development of edge-cracks. The results show that the initial texture has little influence on the single-pass rollability at low temperatures (100 and 150 degrees C), while the influence is significant for rolling above 150 degrees C. Schmid factor and in-grain misorientation axis analyses revealed that the textural effect on the activation of prismatic glide accounted for the observed distinct rollability at elevated temperatures.
