5. 내용 :


The processing of titanium alloys offers extensive opportunities for the control of micro structure, texture, and hence properties. In the first part of the presentation, an overview of the micro structures that are obtained during conventional solidification and deformation processes will be presented. Micro structure evolution in emerging casting, heat treatment, and solid-free form fabrication processes for alpha/beta alloys will also be described. In the second part of the talk, current understanding of the conversion of ingot micro structures to equiaxed ones during the hot working of alpha/beta alloys will be summarized. The application of advanced characterization and modeling tools to describe the evolution of micro structure and texture will be reviewed.
