Regularity of Structural Superplasticity of Hypoeutectoid Steel

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 Ac1, between Ac1 and Ac3, and just above Ac3, When these steels are subjected to superplastic tensile test at...

Summary: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 Ac1, between Ac1 and Ac3, and just above Ac3, 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, microstructures and deformation conditions of the steels.
