Squeeze casting was used for processing two new types of composites: pure Al matrix composites reinforced with fibres of Inconel 601, and AS13 (Al-12% Si) matrix composites reinforced with fibres of Inconel 601 or stainless steel 316L. The fibres are continuous a with a diameter of 12 mu m and their volume fraction in the composites varied from 20 to 80%. The processing conditions were such that no trace of interfacial reaction compound or of matrix precipitate resulting from the dissolution of elements of the fibres could be detected. The quality of the process was attested by Young's modulus and electrical conductivity measurements. Tensile tests were carried out from room temperature up to 300 degrees C. The composites with the pure Al matrix present a remarkable tensile ductility. They thus constitute convenient materials for assessing continuum plasticity models for composites. Properties of composites with the AS13 matrix are much affected by interface adhesion strength. (C) 1998 Acta Metallurgica Inc. Published by Elsevier Science Ltd. All rights reserved.
