چکیده:

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
