Tensile properties of hot rolled AZ31 Mg alloy sheets at elevated temperatures

Study of the microstructure, texture and tensile properties of as-extruded AZ91 magnesium alloy

“…However, there are only two independent modes for basal slip, insufficient to satisfy the von Mises criterion. Because the critical resolved shear stress for the non-basal (prismatic and pyramidal) slip system decreases rapidly with the increase of temperature, the non-basal slip systems are expected to be active at high temperature [4,14,15], contributing to the ductility of Mg alloy. Consequently, the thermomechanical processing is frequently performed at high temperature.…”

Non-Isothermal Simulation of Warm Circular Cup Deep Drawing Processing of an AZ31 Magnesium Alloy Sheet

“…In general, the formability of magnesium alloys is effectively improved by increasing temperature with the activation of non-basal slip systems and twinning. Although most studies investigated the formability of magnesium alloy sheets with square or circular deep drawing, several papers on the warm forming of magnesium alloy sheets indicated that the formability of magnesium alloys was significantly improved at temperatures up to approximately 200 C. [3][4][5][6][7][8] Several research papers conducted FE simulation for the warm forming of magnesium alloy sheets [9][10][11][12][13][14][15] using isothermal conditions with PAM-STAMP or non-isothermal conditions with DEFORM, MARC, and ABAQUS/standard. However, few papers have been published on the FE simulations for the warm forming of magnesium alloy sheets using non-isothermal conditions.…”

Processing and Mechanical Properties of Fine Grained Magnesium by Equal Channel Angular Pressing

“…The activity of nonbasal slip systems leading to annihilation of dislocation and deformation twinning can enhance the ductility of magnesium. 4) At 300 C, distinct cracks were not found in the sample, which is attributable to both the activities of more slip systems and the microstructural contributions, that is, the dynamic recrystallization and the dynamic recovery.…”

“…The fractures occur not only from the top surfaces but also within the samples. With increasing the ECAP processing temperature, the number of cracks decreased, because the activity of nonbasal slip systems, 4) hence the ductility of magnesium, increases with increasing temperature. The activity of nonbasal slip systems leading to annihilation of dislocation and deformation twinning can enhance the ductility of magnesium.…”
