摘　　要：已掌握冷变形度与超塑性力学特性的关系,当总变形量足够时,采用40％以上冷变形度均能获得较佳超塑性。本文还测定了38％和80％两种冷变形度下不同应变速率的m值,观察了550℃保温1小时后水冷的各种冷变形度状态的显微组织。The relation between cold deformation and superplasticity properties is well understood. On Condition that the total deformation is sufficient, 40 per cent of cold deformation will bring about good superplasticity. The values of m for different strain rates at 38 per cent and 80 per cent cold deformations are determined. The microstructure after soaking at 550℃ for one hour is observed.
