Multiscale Computer Simulation of Drawing with Statistical Representation of TRIP Steel Microstructure

Resumo

The drawing of TRIP steel rod is analyzed. Such steel offers a range of performance benefits. For the case where the microstructure of TRIP steel must be taken into account, problems with traditional process design based on finite-element computer simulation are noted. By means of multiscale simulation, the microstructure of the steel and the dynamic structural and phase transformations (the TRIP effect) may be taken into account. The proposed approach to multiscale modeling is tested for the drawing of TRIP 700 steel in a traditional system. The possibility of controlling the distribution of the steel’s properties by means of the process parameters is assessed. By the proposed method, the deformational interaction of the microstructural elements of TRIP steel may be studied, and the computer resources required by the model may be dramatically decreased.
