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.
