  • A cost effective foundry method for the preparation of structural grade discontinuously reinforced aimcs
    Kevorkijan, Varužan
    In this work, it was demonstrated that the wetting between ceramic particles and molten metal can be activated by exothermic interfacial reactions (e.g. ▫$Si+C\toSiC$▫ or ... ▫$3TiO_2+3C+4Al\lo3TiC+2Al_2O_3$▫). In this way, two methods of processing for introducing larger amounts of fine SiC particles into a Al alloy melt without unwanted chemical reactions between the matrix and the reinforcement were developed. The introduction of fine (less than 6\mum) rounded-off SiC particles combined with a significant reduction in casting and extrusion defects caused by cost effective HIP treatment without encapsulation resuts in superior tensile properties. Moreover, in a defect-free composite, high aspect rati reinforcements like SiC whiskers and platelets can be sucessfully used in order to improve the mechanical properties of final parts.
