COOL DEFORMATION PROPERTIES OF AN X70 INDUSTRIAL STEEL

摘要：

In the past few years cool deformation research at McGill Univ. has been centered on experimental steels. In this work an X70 industrial grade is examined by means of torsion testing.Following a full hot rolling physical simulation, three levels of cool deformation strain, 0.06,0.12,and 0.2 were applied at 400℃ and the subsequent strength were measured at room temperature;and the results were compared with the no-cool deformation situation.The effect of cooling rate after the finishing stage on the cool deformed microstructure and properties was also examined.The results show that by applying even a small amount of deformation, the yield point increases remarkably.
