Over recent years, aluminium composite materials have attracted increasing interest as potential candidates for replacing conventional monolithic alloys in a variety of structural applications where the weight of structural materials is critical. However, the lack of a satisfactory and cost effective technique, especially for the production of complex shaped aluminium MMC components, has prohibited widespread commercial use of these materials. This is a main driving force behind the performance of the present research which had the following two main objectives:- 1) The development of a novel casting technique based on the use of an EPS pattern mould and a counter-gravity mould filling. This involved the design and manufacture of a special casting unit. 2) The evaluation of the proposed casting technique compared with a gravity pouring EPC method through a series of casting trials using both a Duralcan (reinforced with 15 vo!. % SiC particles) and an aluminium alloy (LM25). This included the evaluation of casting soundness, tensile properties at ambient temperature, microstructure, and fracture surface of tensile tested specimens...cont'd.
