摘要：
High tensile strength and large elongation are obtained by applying the Q&P process to the hot rolled or directly cold rolled AISI 430 ferritic stainless steels characterized by ferrite, twin martensite and retained austenite. Both the prior formed martensite during the quenching and the TRIP effect of the retained austenite account for the improved tensile strength and the retained austenite gives a promotion to the large elongation.
