Martensitic Transformation of Austenitic Stainless Steel Cruciform Geometry Sample by Biaxially Fatigued Cycling

Abstract:

A specifically designed cruciform-shaped austenitic stainless steel AISI 321 sample was subjected to ex-situ biaxial tension-compression cycling to establish ferromagnetic martensitic phase conversion under the action of plastic deformation. The time-of-flight neutron diffraction technique was employed for in-plane residual stress determination in this sample for both the austenitic and martensitic phases. The 2D data enabled determination of the macro-, micro-, hydro- and deviatoric contributions to the total phase stresses.
