| 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. |
