Influence of Temperature and Strain Rate during Thermomechanical Treatment of a Metastable Austenitic TRIP Steel Compacted by SPS/FAST

High‐alloy Fe–19Cr–3Mn–4Ni–0.5Si–0.17N–0.17C TRIP/TWIP steel samples are processed by SPS/FAST (Spark Plasma Sintering/Field‐Assisted Sintering Technology) and subsequently thermo‐mechanically treated by Quenching‐Deformation‐Partitioning (QDP). Because a martensite start temperature ( M s ) does not exist for this material, it is not possible to form as‐quenched α’‐martensite during the QDP treatment. Therefore, α’‐martensite is formed by...
