摘要

The curve of the relation between fracture elongation and temperature for unltrafine grained low alloy hypoeutectoid steels generally shows that three peaks occur at temperatures just below A_(c1),between A_(c1) and A_(c3),and just above A_(c3) ,When these steels are subjected to superplastic tensile test at different temperatures,the value of the last one is the lowest and the other two peaks are different one from another depending on components,mi-crostructures and deformation conditions of the steels.
