Effect of Thermo-Mechanical Treatment on Texture and Microstructure Evolution of Polycrystalline Alpha Titanium.

摘要

The present work attempts to establish a unified path model for characterization as well as prediction of microstructure evolution in terms of texture and micro-texture, in commercially pure titanium that has undergone thermo-mechanical processing. Two deformation temperatures, room temperature (cold rolling) and 260C (warm rolling), and five different deformation levels of 20%, 40%, 60%, 80% and 95% were used in the present investigation. In this report only the experimental results of texture analysis is presented. The modeling of processing path model, texture evolution and the experimental results for other temperature ranges will be presented elsewhere.
