Abstract
The deformation mechanisms of the metastable austenite phase of a transformation induced plasticity (TRIP) stainless steel, AISI 301LN, have been investigated by compression of multicrystalline micropillars of different crystallographic orientations, with particular attention on the strain-induced phase transformation from austenite to martensite. Intergranular shearing and twinning were observed to be the primary deformation mechanisms, with a predominant <122> orientation developed in the aust...
