Improved Mechanical Properties of AZ31 Alloy Fabricated by Multi-Directional Forging

摘要：

　　In this work, the tensile properties of AZ31 Mg alloy deformed by multi-directional forging (MDF) were investigated at room temperature.And the enhanced mechanical properties of yield strength of 93 MPa, ultimate tensile strength (UTS) of 253 MPa and elongation of 29% were achieved.It is discovered that the MDF deformation makes the crystallographic orientation of original as-cast microstructure randomization, providing the condition for the following twinning during tensile deformation.In addition, the original fine grains and continuously refined grains can enhance the strength by restricting the growth of grains and motion of dislocations.
