Deformation Temperature Path Effects on Martensitic Hierarchy and Strength–Ductility in Automotive Ti–Zr Microalloyed Steel
This study examines how deformation temperature paths affect martensitic hierarchy and the strength–ductility balance of an experimental low‐carbon Ti–Zr microalloyed ultrahigh‐strength steel. Isothermal three‐pass compression at 950, 1000, or 1050 °C (routes A–C) was compared with decreasing‐temperature paths of 1050–...
