    Influence of Heating Rate on Annealing and Reverse Transformation Behavior of TRIP Steels Having Martensite as Starting Microstructure

    The influence of heating rate on the annealing and transformation behavior is investigated in TRIP steel having martensite as the starting microstructure. A higher heating rate preserves the hierarchical struc...

    Influence of the Initial Microstructure on the Heat Treatment Response and Tensile Properties of TRIP-Assisted Steel

    Microstructure evolution and mechanical properties were investigated in transformation-induced plasticity (TRIP) steel having a different initial microstructure. Compared with the cold-rolled structure that ev...

    Influence of the Initial Microstructure on the Reverse Transformation Kinetics and Microstructural Evolution in Transformation-Induced Plasticity–Assisted Steel

    The reverse transformation behavior upon heating to intercritical temperature was studied in Fe-0.21C-2.2Mn-1.5Si (wt pct) alloy with three initial microstructures. One is the cold-rolled (CR) structure and t...

    Medium-Alloy Manganese-Rich Transformation-Induced Plasticity Steels

    The manganese concentration of steels which rely on transformation-induced plasticity is generally less than 2 wt pct. Recent work has highlighted the potential for strong and ductile alloys containing some 6 ...
