Abstract
Some deep drawing characteristics at elevated temperatures were investigate d for the SCPI steel sheets by using a Cr-coated die. For this investigatio n, six different temperatures between room temperature and 250 degreesC, an d six different drawing ratios ranging from 2.4 to 2.9 were considered. As a result, the limiting drawing ratio, the maximum drawing force and the max imum drawing depth were found to be affected sensitively by temperature, an d more stable through-thickness strain distribution was observed at elevate d temperatures. Some experimental results compared favorably with theoretic al results obtained by using the finite element method.
