at elevated temperature. The compressive creep behavior of ageing-treated Mg-xSn (x=3%, 5%) alloys was investigated at the temperatures of 423 and 473 K and the stresses from 25 MPa to 35 MPa. When.... The calculated value of stress exponent, n=6.3, suggests that the compressive creep behavior of the ageing-treated Mg-5%Sn alloy is controlled by dislocation creep at the temperature of 473 K......
