A Study on the Warm Deep Drawability of Sheets in Cr-Coated Die

Some deep drawing characteristics at elevated temperatures were investigated for the SCP1 steel sheets by using a Cr-coated die. For this investigation, six different temperatures between room temperature and 250°C, and six different drawing ratios ranging from 2.4 to 2.9 were considered. As a resul...

Description
Summary:Some deep drawing characteristics at elevated temperatures were investigated for the SCP1 steel sheets by using a Cr-coated die. For this investigation, six different temperatures between room temperature and 250°C, and 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 maximum drawing depth were found to be affected sensitively by temperature, and more stable through-thickness strain distribution was observed at elevated temperatures. Some experimental results compared favorably with theoretical, results obtaine by using the finite element method.[PUBLICATION ABSTRACT]
