摘要：

It is shown that a high strength 7055 aluminum alloy with partially recrystallized initial structure exhibits superplastic behavior in the temperature interval 400-490 degreesC within a wide strain rate range from 8.3 x 10(-5) to 3.3 x 10(-2) s(-1). Maximum total elongation of about 960% and strain rate sensitivity coefficient, m, of 0.6 were obtained at a temperature of 450 degreesC and a strain rate of 3.3 x 10(-4) s(-1).
