Abstract

Controlling texture and microstructure evolution during annealing process is very important for advanced steel. Theories to explain annealing process are complicated and always case dependent. Our recently developed simulation based Monte Carlo method offers an effective tool for studying annealing process and can be used to verify the arbitrarily defined theories that govern annealing process. The computer model is able to take Orientation Image Microscope (OIM) measurements as an input. The abundant information contained in OIM measurement allows the computer model to incorporate many structural characteristics of polycrystalline materials such as, texture, grain boundary, grain shape and size, phase composition, chemical composition, stored elastic energy, and residual stress. The outputs include various texture functions, grain boundary and grain size statistics that can be verified by experimental results. Graphical representation allows us to perform virtual experiments to monitor each simulation step of the structural transaction. An example of applying this simulation to Si steel is given.
