摘要：
Si(3)N(4)w/Al-Mg, Si(3)N(4)w /Al-Cu composites fabricated by squeeze casting were extruded and the superplastic characteristics were investigated. Si(3)N(4)w /Al-3wt%Mg composite indicates the m value of 0.4 and the total elongation of about 260% at the strain rate of 10(-1)s(-1) and at 858 which is just above solid temperature of Al-3wt%Mg matrix. But Si(3)N(4)w /Al-2wt%Cu shows the total elongation of about 100%.
