Summary:

Titanium alloys containing small additions of boron possess novel microstructures that exhibit significant improvements in structural efficiency while retaining useful fracture properties. Thermo-mechanical processing is an important step in the shape-making of Ti-B alloys to engineer microstructures and to enhance properties. In this study, Ti-B alloys produced via the pre-alloyed powder metallurgy method are subjected to hot working under various temperature and strain rate conditions. The microstructural evolution in hot worked alloys is studied in detail to understand the influence of various parameters on the workability. Optimization of hot work parameters is performed to obtain desired microstructures. Tensile properties of hot worked alloys are evaluated and correlation between microstructure and properties will be discussed in this presentation.
