A Linear Model of Processing Path in Cubic-Orthotropic System
Modeling the texture evolution in polycrystalline materials during thermomechanical processing is an important aspect of the newly developed design methodology, microstructure sensitive design (MSD). The texture coefficients are used in this study as a representation of microstructure and their evolution describes the processing path. A new methodology based on a conservation principle in orientation space is utilized in this work to model the processing path in cubic-orthotropic system. Least squares error method was used to improve the accuracy of simulation results from the processing path function developed in this study. The processing path function developed in this study empowers the MSD users to find out how to optimize and tailor microstructures with desired properties.
