| Abstract: | The rules of stength and ductility for 45 steel under temperature range from solidus to 600℃ were measured by a thermal stress/strain simulator Gleeble 1500. The influence of thermal history, strain rate and cooling rate on strength and ductility at solidifying region, Austenitic region and γ→α region was studied. The mechanism of cracking in these three regions was investigated. |

| Keywords: | strength at high temperature ductility at high tempenature crack sensitivity carbon steel |
