Abstract

The laws of changing the mechanical properties of sheet austenitic–martensitic VNS9-Sh (23Kh15N5AM3-Sh) TRIP steel are studied when the static strain rate changes in the range 0.1–20 mm/min (8.3 × 10–5–17 × 10–3 s–1). The 0.35-mm strip under study is characterized by a high martensite content (≈100%) in the surface layer at an average content of 80–85%. The transformation induced plasticity effect is maximal at a strain rate of 0.1 mm/min (8.3 × 10–5 s–1).
