Abstract

Abstract

The microstructure and mechanical properties of Mg-8Al-1Zn-xTi(x=0.05,0.15,0.3) magnesium alloy containing titanium with different titanium contents were tested and analyzed, and the microstructure and mechanical properties of Mg-8Al-1Zn alloy without titanium were compared. The results show that the addition of alloy element Ti can refine the alloy grain and improve the mechanical properties of the alloy. The average grain size of the alloy first decreases and then increase, and the mechanical properties first improves and then declines. Compared with Mg-8Al-1Zn alloy without Ti, the average grain size of Mg-8Al-1Zn-0.15Ti alloy containing Ti decreases by 7.2 μm, tensile strength increases by 32 MPa, yield strength increases by 33 MPa, the elongation after fracture increases by 3.8%, and the tensile fracture mode changes from mixed fracture to plastic fracture.
