초록
In this study, an experimental investigation was conducted to evaluate the forming limit diagrams (FLDs) of two types of magnesium alloy sheets at elevated temperatures. The FLDs were determined through Nakajima tests using a high-temperature Erichsen testing machine. Two magnesium alloys—AZ31B and E-form—were selected for comparison, characterized by basal and non-basal initial texture, respectively. The experiments were performed over a temperature range from room temperature to 200°C. The influence of the initial crystallographic texture on the FLDs was analyzed, and the temperature-dependent formability of the two alloys was comparatively assessed.
