In this study, 17Mn4 pressure vessel steel and AISI 304 stainless steels were joined with using ER 309L TIG welding wire. Variation of hardness values along the welded specimens was determined. Finite element (FE) analyses were conducted by fixing 2-D models for welded component. After entering the linear and nonlinear properties of the materials for different regions on the welded samples, static analyses were conducted for the different stress values. Finally, fatigue analyses were performed in order to determine fatigue life of each region as the welded component.

It will be shown that the presented mathematical model, which uses an index called the entropic index that measures the nonextensivity of ...

For example, the fatigue endurance limit of austempered ductile cast iron is strongly influenced by volume fraction of retained austenite. The austenitisation temperature is also a significant factor. It has been shown, by the use of multi-stage heat treatments, that the fatigue endurance limit is increased by refinement of the prior austenite grain size, independent of the retained austenite volume fraction and retained austenite carbon concentration. This is caused by a decrease in the sub-critical fatigue crack nucleus size due to crack arrest at the prior austenite grain boundaries.
