Abstract
There are few commercial alloys available for processing in the semi-solid state, notably the A356 and A357 alloys, both based on Aluminium-Magnesium-Silicon system. In recent projects, it was developed new alloys in the aluminum-silicon-copper system which generated seven patents (four international: BR200805448-A2, BR200805449-A2, A2-BR200805450, BR200805451-A2). The Foundry Laboratory …
