Summary
In this work a wide range of roughing (deformation in the austenite recrystallised region) and finishing (deformation in the non-recrystallised region) strains and isothermal holding times were used to clarify the effect of processing parameters on the transformation kinetics and mechanical properties of 0.2C-1.55Mn-1.55Si (wt%) TRIP steel. The results have highlighted the complex relationships between multi-phase microstructure and mechanical properties of TRIP steel. The presence of the triclinic carbides, formed during isothermal holding, deteriorated the mechanical properties of steel studied.
