Influence of the Phase Transformation Behaviour on the Microstructure and Mechanical Properties of a 4.5 wt.-% Mn Q&P Steel* Open
“Quenching and Partitioning” (Q&P) steels have a microstructure consisting of a tempered martensitic matrix with austenite islands, which can be stabilized to room temperature due to the C partitioning from martensite to the remaining aust…

Influence of the Quenching and Partitioning Process on the Transformation Kinetics and Hardness in a Lean Medium Manganese TRIP Steel Open
The quenching and partitioning (Q&P) process of lean medium Mn steels is a novel approach for producing ultra-high strength and good formable steels. First, the steel is fully austenitized, followed by quenching to a specific quenching tem…
