SIMULATION OF THE STATIC MECHANICAL BEHAVIOUR OF TRIP STEELS BY MICRO-MECHANICAL MODELLING

Abstract
TRIP (TRansformation-Induced Plasticity) steels display a composite behaviour originating from the different constituent phases present in these steels: polygonal ferrite, bainitic ferrite, and martensite/austenite. This behaviour results in an excellent combination of a large uniform elongation and high strength. In order to understand the composite behaviour of the different phases, the constituents were prepared as separate alloys. The stress-strain relationships of these alloys were simulated by physically based micro-mechanical models based on the Mecking-Kocks theory. Physical properties such as the microstructural parameters, the dislocation density and the chemical composition of the different phases were taken into account. The influence of the transformation of the metastable austenite was included by using a generalized form of the Olson-Cohen law. The static stress-strain properties of the multiphase steels were modelled by the successive application of Gladman-type mixture laws. Besides the simulation of the stress-strain curves, the model also generates detailed information of stress and strain partitioning between the different phases during a static tensile test.
