Purpose: Experimental verification of various thermo-mechanical (TM) processing schedules, with aim to modify the structure characteristics using press forging of Si-Mn TRIP (Transformation Induced Plasticity) steel, was described. Design/methodology/approach: High strength and ductility of TRIP steels is attributed to the TRIP effect resulting from the strain induced martensitic transformation of the retained austenite in the multiphase (ferrite, bainite, martensite) microstructure. In order to rationalize the retained austenite (RA) volume fraction in steel microstructure, several TM schedules were employed at experiment where different austenite conditioning was considered. Findings: The various multiphase structure characteristics were then resulting after TM processing of steel, where different volume fractions of ferrite, bainite and RA were received in the steel. The modification of structural characteristics of steel then influenced the deformation behavior and mechanical properties TRIP steel. Research limitations/implications: The present work also focused on monitoring of RA transformation during incremental mechanical straining using in-situ neutron diffraction technique. Originality/value: This non-convenient experimental method was used to characterize the kinetics of RA transformation and its stability during consecutive straining.
