摘要：

Al-Zn-Mg system alloy matrix composite reinforced with 20 vol% Si3N4 whiskers has been extruded at 773 K with a reduction ratio of 100:1, and its superplastic properties have been investigated at an elevated temperature by a constant velocity tension test. A maximum elongation of 240% was obtained at 5 X 10(-1) s-1.
