Summary

The low pressure and gravity casting processing techniques offer the component designer an opportunity to produce pieces with increased complexity over those able to be fabricated via the high pressure die casting route. The design of appropriate microstructures for the enhancement of elevated temperature properties is dependent on the chosen processing route, with the low pressure and gravity techniques allowing for post-cast manipulation of the microstructure through heat treatment. There are competing microstructural requirements for strength and creep resistance in casting alloys, and the optimised microstructure must, of necessity, be a compromise. The contributions from solid solution strengthening, grain boundaries and precipitation processes are described, with particular reference to elevated temperature magnesium alloys.
