Effect of Microstructure on Shear Deformation in (α + γ) Duplex Stainless Steel

Duplex stainless steel has excellent strength and corrosion resistance, it is widely used such, for example, in plant applications. The microduplex structure affects not only the physical properties but also deformation behavior. fracture considered to be caused by peeling duplex interface been confirmed various experiments parts manufacturing factories, there are few detailed references morphology of structure. In this study, we examined relationship between behavior shearing test with load, horizontal or vertical stretching direction austenite phase. latter load divided delayed fracture. results showed that acts as resistance orthogonal itself.
