文摘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 o C 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.
