The effect of strain rate on the flow stress of a low carbon high strength ferritic steel that contains nanometer size Cu–Ni–Al precipitates is found to be much less than that of HSLA 65 that does not have such precipitates. This result is in agreement with the theory that such precipitates locally lower the Peierls stress for screw dislocations in body-centered cubic iron. The fracture mode in...
strain induced precipitation in hsla-100 steel was investigated by conducting hotcompression and relaxation tests at temperature range of 850°c to 1100°c and strain rate of 0.001s-1 to 1s-1. the absence of dynamic recrystallization at temperatures below 1000°c was attributedto the influence of dynamic precipitation. the stress relaxation tests showed that strain inducedprecipitation is possible...
Microalloyed steels containing copper in order to promote precipitation hardening are one of the approaches adopted to develop new materials with high mechanical strength but minimized carbon content to assure good weldability. Besides that, the thermomechanical processing of such alloys can eliminate the subsequent quench and tempering heat treatments required by conventional steels. The effec...
