Abstract

A processing path model proposed earlier by Bunge is used for the prediction and optimization of texture in polycrystalline hexagonal materials. The model relies on a principal of conservation in the orientation space and the existence of a texture evolution parameter. The numerical simulations from a well-established crystal plasticity model produced the initial data for the calculation of the processing path parameters. The model is then capable of predicting the texture evolution starting from other initial textures for any specific deformation path. The simulated results from the processing path model agree well with those from the crystal plasticity model. The family of processing path lines developed based on the present model can be used as a guide to optimize the processing paths that will lead to a microstructure with desired properties.
