Abstract

1499934 Alloy treatment in pressure die casting SOC DE VENTE DE L'ALUMINIUM PECHINEY 3 April 1975 [4 April 1974 13650/75 Heading B3F In a process for treating a metal alloy in the form of a mixture of liquid and solid phases, the normally cast alloy is heated to a temperature between the liquidus and solidus points to liquefy a well defined proportion, greater than 40% by weight, and is maintained for a period of a few minutes to a few hours, preferably 5 minutes to 1 hour, so that the original dendritic phase at least starts to globularize. The solid/liquid material thus formed may be pressure cast into a mould at pressures similar to those used in casting liquid metal, with the advantage of reducing die wear, better quality and greater throughput, since the heat needed to be removed by the die is reduced. The treated material may be cooled and reheated without affecting the thixotropic characteristics. Examples of aluminium alloys of the A-S9U3 [Al-9%, Si-3% Cu) type and A-4USG [0À2% Fe, 4À3% Cu, 0À75% Si, 0À5% Mg and 0À6% Mn) type continuously cast in the normal manner and then reheated to 580‹ and 630‹ C. respectively show that the time held at temperature significantly affected the thixotropic casting properties of the materials.
