Thixotropic Structure Generation and Semisolid Casting of Aluminium and Magnesium Alloys. A range of aluminium and magnesium alloys will be prepared by controlled-pouring to produce structures suitable for semisolid forming. The conditions around grain nucleation and growth will be studied to ascertain the controlling factors in producing suitable microstructures. A computer model to simulate the thixotropic structure formation and define the processing parameters will be developed.

A range of aluminium and magnesium alloys will be prepared by controlled-pouring to produce structures suitable for semisolid forming. The conditions around grain nucleation and growth will be studied to ascertain the controlling factors in producing suitable microstructures. A computer model to simulate the thixotropic structure formation and define the processing parameters will be developed. Semisolid casting using the produced feedstock will lead to extensive knowledge about the effect of different microstructures and alloys on semisolid castability. Outcomes from the project will significantly advance the scientific understanding of the thixotropic structure generation and accelerate the development of semisolid processing technology.Read moreRead less
Surface Nanocrystallization and Surface Alloying of Nonferrous Alloys. The research will offer materials scientists a totally new way to undertake surface modification for nonferrous alloys. The low temperature surface alloying technique to be developed will considerably improve the surface durability, therefore increase the service life of components. Combination of the surface alloying treatment with the ageing process can save energy and lower the cost of product. This will enhance Austral ....Surface Nanocrystallization and Surface Alloying of Nonferrous Alloys.
