TiAl based alloys are being developed as high temperature structural materials for aerospace and automotive applications and thus their creep resistance (long-term strength at elevated temperatures) is critical. This project aims at developing creep resistant TiAl alloys through a combination of addition of rare earth and severe plastic deformation. It is expected that a refined and stablised microstructure consisting of submicron lamellar grains and nanosized lamellae be obtained. This will result in a highly creep resistant prototype TiAl material and leads eventually to the development of commercial TiAl alloys.Read moreRead less

Simulation and Modelling of Interactions between Dislocations and Precipitates in High Strength Light Alloys. Most light alloys are strengthened by highly dispersed nanoscale precipitates. The mechanical behaviour of these alloys is determined by the intimate coupling between precipitate microstructure (size, shape and spatial distribution) and dislocation activities (by-pass, shearing and adsorption at interfaces).

CHARACTERISATION OF DIE CAST MAGNESIUM ALLOYS FOR AUTOMOTIVE POWER TRAIN COMPONENTS. A new group of magnesium die casting alloys has recently been developed for fabricating automotive power train components. While these alloys exhibit good tensile yield strength at both ambient and elevated (100-200°C) temperatures, they are prone to excessive creep deformation when exposed to moderate levels of loads at temperatures above 125°C. The aim of this project is to characterise microstructures of th ....CHARACTERISATION OF DIE CAST MAGNESIUM ALLOYS FOR AUTOMOTIVE POWER TRAIN COMPONENTS. A new group of magnesium die casting alloys has recently been developed for fabricating automotive power train components. While these alloys exhibit good tensile yield strength at both ambient and elevated (100-200°C) temperatures, they are prone to excessive creep deformation when exposed to moderate levels of loads at temperatures above 125°C. The aim of this project is to characterise microstructures of these alloys subjected to controlled levels of creep deformation in the temperature and stress regime of interests, with a view to identifying microstructural factors that are important in determining the creep resistance of die cast magnesium alloys. The outcome of this project will provide useful guidelines for further improvements in creep resistance of these alloys and development of new die cast alloys with higher creep resistance at elevated temperatures.Read moreRead less
