Summary on Grant Application Form |

The proposed research is concerned with the design of computer-based models for the prediction of microstructure during thermal treatment and mechanical processing of gamma-based titanium aluminides, using advanced phase transformation theory. The aims are to assess the viability of making microstructural predictions to within useful accuracy and to apply the methodology to an important new metallic material. To the applicants' best knowledge, such detailed calculations have not been attempted before either in or outside UK. The main objective is to model the microstructural evolution of the alpha, gamma and alpha-2 ordering phases as a function of thermal treatment, mechanical processing, and alloy chemistry (including oxygen). Other tasks are to predict and measure time-temperature-transformation (TTT) and continuous heating and cooling transformation diagrams and to conduct experimental validation and calibration of the computer models.The proposed work will complement existing research programmes at QUB, on modelling the evolution of microstructure and phase transformation during processing of titanium alloys. The extension from Ti to TiAI alloys is a logic development. The present work on titanium aluminides would also help maintain the highest international standing that UK scientists have earned over the years in modelling and characterisation of phase transformations in major and novel alloy systems.
