Abstract
A method of producing light alloy castings by foundry technology in which, after solidification and shake-out, the casting is subjected to a heat-treatment cycle comprising a solution heat-treatment step at a temperature high enough to put into solution the phases precipitated in the course of the solidification of the casting, possibly followed by a quenching step and an ageing step, wherein the solution heat-treatment step is performed at least partially in hot isostatic pressing conditions.
