Influence of Additions Sb on Mechanical Properties and Deformation Features of AZ31-Mg Alloy
The mechanical properties and deformation features of AZ31-x%Sb alloys have been studied by means of the measurement of the ultimate tensile properties (UTS) and TEM observation. Results show that the UTS of AZ31 alloy is effectively enhanced to 297 MPa from 222 MPa, by additions of 0.84% Sb element, at room temperature, and the ultimate tensile strength of the alloy is still maintained up to 189MPa as temperature elevated to 200°C. Contrast analysis shows that the deformation mechanisms of AZ31-0.84%Sb alloy are twins and dislocations activated on basal and non-basal planes. The alloy displays the different deformation features at different deformation conditions.
