Symposium Coupling Advanced Characterization and Modeling Tools for Understanding Fundamental Phase Transformation Mechanisms: An MPMD Symposium in Honor of Hamish Fraser
Presentation Title Advanced Characterization and Modeling Tools in the Context of Corrosion
Author(s) Oumaima Gharbi, Shravan Kairy, Nick Birbilis
On-Site Speaker (Planned) Nick Birbilis
Abstract Scope Various phase transformation mechanisms and pathways in titanium alloys have been systematically investigated in Hamish group for a long period of time, using both advanced characterization techniques, such as aberration corrected scanning transmission electron microscopy and 3D atom probe tomography, and computational simulation, such as phase field simulation. In this presentation, the focus will be laid on two topics: 1. The exploration of nano-scale instabilities in titanium alloys, including omega phase (athermal omega phase and isothermal omega phase), O’ phase and O” phase; 2. The development of various fine scale alpha microstructures in titanium alloys, including refined alpha microstructure, more-refined alpha microstructure and super-refined alpha microstructure. Novel understanding of phase transformation mechanisms and pathways in titanium alloys, that could be potentially applied to manipulate microstructural evolution and modify mechanical performance of titanium alloys, will be introduced.
