摘要	The high temperature tensile properties and microstructural evolutions of Mg-5Y-4Nd (WE54) alloys with extrusion and extrusion followed by equal channel angular extrusion (ECAE) were investigated at elevated temperatures. The results suggested that the as-extruded specimens exhibited enhanced ductility at 400 and 450 degrees C, and a maximum elongation of 290% was obtained at 450 degrees C and 1 x 10(-3) s(-1), corresponding to the m-value of 0.38. On the other hand, ECAE following extrusion led to high strain and/or superplasticity behaviors, and a maximum elongation of 600% was achieved at 400 degrees C with the m-value of 0.49. In addition, the active energies of WE54 alloys with different fabrication routes were examined and compared. (C) 2008 Elsevier B.V. All rights reserved.
