Prediction of cold heading quality with high strain rate compression tester

$15.00

With the aid of a high strain rate compression tester, known as a split Hopkinson pressure bar tester, cold heading quality (CHQ) of two steel grades (SUS XM-7 and SAE52100) were examined by measuring the dynamic plastic flow resistance. The experimental results obtained by utilizing this equipment were compared with those from conventional material tests. The experimental results revealed that in the stable austenite stainless steel, SUS XM-7, the optimum austenite grain size range for cold heading is considered to be relatively large because of lower dislocation density.
