AbstractThe structures of Al-Si, Sn-Mg2Sn, Pb-Sb and Cd-CdSb eutectic alloys have been modified to a fibrous form by rapid unidirectional solidification. The tensile and compressive properties of these eutectics have been studied as a function of microstructure. It is shown that these modified eutectic alloys with the exception of the Pb-Sb eutectic alloy show significant fibre reinforcement. The lack of composite reinforcement in the modified Pb-Sb eutectic alloy is attributed to the premature failure of the reinforcing phase. Resume Par solidification rapide et unidirectionnelle les auteurs ont obtenu une structure fibreuse avec les eutectiques Al-Si, SnMg2 Sn. Pb-Sb et Cd-CdSb. Les proprietes en tension et en compression de ces eutectiques ont ete etudiees en fonction de la microstructure et il est montre que les structures ainsi modifiees, sauf pour le cas de l'eutectique Sb-Pb, presentent un renforcement dil aux fibres. L'exception notee dans Ie cas de la structure alignee de l'eutectique Sb-Pb est a...
