چکیده انگلیسی
Low temperature mechanical properties of AZ91D magnesium alloy fabricated by solid recycling process from recycled scraps were studied. Various microstructural analyses were performed using optical microscopy (OM) and scanning electron microscopy (SEM). The recycled specimens consist of fine grains due to dynamic recrystallization and the interfaces of original individual scraps are not identified. Tensile tests were performed at a strain rate of 5Ã10â3 sâ1 at room temperature (27 °C), â70, â100 and â130 °C, respectively. Ultimate tensile strength of the specimens increases slightly with decreasing the tensile temperature, and elongation to failure decreases with decreasing the tensile temperature. The tensile specimens at â130 °C show the highest ultimate tensile strength of 360.65 MPa and the lowest elongation to failure of 5.46%. Impact tests were performed at room temperature (27 °C), â70 and â130 °C, respectively. Impact toughness decreases with decreasing the impact temperature. The impact specimens at â130 °C show the lowest impact toughness of 3.06 J/cm2.
