Research on the ratio of the hot stamping and the superplastic forming in a complex forming process

摘要

This article describes a high rate superplastic forming. The high rate superplastic forming technology is a new complex process,which integrates hot stamping and superplastic forming .It has feature of rapidity of the hot stamping and character of excellent formability of the superplastic forming. It can effectively solve the hard formation of cold stamping and the low efficiency of superplastic forming. We obtained the best proportion of the hot forming and the superplastic forming through simulation numerical analysis and simulation experiment.
