Production of Highly Reinforced Dispersion-Strengthened Composite Material Based on Aluminum by Internal Oxidation

Resumo

Currently dispersion-strengthened composite materials are used increasingly widely in special engineering industries. The main obstacle in the way large-scale implementation of these materials are high cost and the problem of providing a strong bond between particles and matrix under conditions of uniform particle distribution within a matrix. A method is proposed in this work for liquid-phase preparation of highly reinforced dispersion-strengthened composite material based on an aluminum alloy matrix reinforced with discrete ceramic particles. The technology developed makes it possible to reduce the cost of the dispersion-strengthened composite material obtained, in particular as a result of not using powder components and preparing composite material in a single stage. In this case a strong interphase boundary is provided between matrix and filler.
