对01420合金的形变热处理工艺和超塑性进行了研究.采用新的形变热处理工艺，即“固溶处理后炉冷到300℃直接轧制、再结晶、人工时效”，得到了晶粒度为8～10μm的细晶材料；对合金的超塑性变形行为进行了研究，获得的超塑延伸率950％；m值为0.78．
The deformation heat treatment and superplasticity of the alloy 01420 were studied.The new deformation heat treatment process was adopted, that is, “direct cooling, recrystallization and artificial aging after cooling to 300 ℃ in the solution treatment furnace”, and the grain size was 8 ~ 10μm. The superplastic deformation behavior of the alloy was studied and the superplastic elongation was 950%. The m value was 0.78.
