Effect of thickness and heat treatment on the toughness of AISI 1045 and AISI 6150 sheet steels

Toughness is the combination of strength and flexibility, in the presence of elastic and plastic tensions. This quantity equals the surface area under the graph of stress-strain. Kahn standard sample is used for the comparison of toughness. The heat treatments of annealing and tempering were used for AISI 1045 samples; and annealing and austempering processes for AISA 6150 samples. To investigate the effect of thickness, 6 different thicknesses were used. In this study, the J parameter is used as a parameter to compare the toughness that is evaluated by the division of the surface area of Kahn sample F-X plot to its cross section
