Technical Description
This invention introduces a novel thermal processing method for producing low-carbon, lean-alloy quench and partitioned (Q&P) steels with a dual-phase microstructure. By precisely optimizing chemistry variations and partitioning parameters, the method yields high-volume fractions (~22%) of stabilized retained austenite within a martensitic matrix, achieving exceptional strength-to-ductility balances for modern applications.
