Influence of the strain rate on the mechanical and technological properties of steel sheets

[摘要] The paper analyses the influence of strain rate on the behaviour of un-alloyed steels with R e (yield strength) in the range of 210 �? 550 MPa in the deformation process. It analyses the results of the influence of strain rate ranging...
