摘要：
Fine-grained WZ73 magnesium alloy with the grain size of 1.6mum was produced by Equal-Channel-Angular Extrusion. The material exhibited tensile yield strength of 293 MPa, tensile strength of 350 MPa. and relatively large elongation of 18% at room temperature. The yield strength was almost unchanged up to 473 K. In addition, large superplastic elongation of over 300% was obtained at a temperature of 673 K.
