The transformation of austenite to martensite is fundamental to the hardening of carbon steels. This transformation plays an important role for the mechanical behaviour of low-carbon ferrous alloys containing about 10 vol.% retained austenite. The effect, known as transformationinduced plasticity (TRIP), is manifested by unusual high work hardening and high uniform elongation—properties very desirable for thin sheets applied for automotive parts. Tensile tests of cold-rolled sheets at room temperature allowed to study the retained austenite stability against strain-induced martensitic transformation. The influence of the processing texture (specimen orientation) and the strain rate (2 × 10−2 and 2 × 10−3 s−1) on the uniform elongation was observed experimentally. Results show that a homogeneous microstructure and the absence of initial blocky martensite ensure long deformation paths. At the same time, tensile data reveal only a small influence of deformation parameters on the ultimate strength.
