Microstructure and tensile properties of rolled Mg-5.5 mass%Zn-0.6 mass%Zr alloy
The microstructure and tensile properties of a rolled specimen of Mg-5.5 mass%Zn-0.6 mass%Zr alloy are investigated. A relatively small grain size of 15.9 μm was obtained in the rolled specimen. The rolled magnesium alloy exhibited higher strength than the annealed specimen at room temperature, while the elongation was almost the same as the annealed specimen. Also, a large elongation of 501% was obtained at 573 K for the rolled specimen. A smaller grain size of 9.6 μm was obtained due to dynamic recrystallization during the tensile test at 573 K.
