摘要:
A reinforced metal composite comprises a mixture of fused yttria and a metal matrix selected from the group consisting of Ti, Nb, Fe, Co, Ni, Ti alloys, Co based alloys aluminides of Ti, aluminides of Ni, aluminides of Nb and their mixtures. Preferably, the metal matrix is Ti or a Ti alloy which has a low Cl content, e.g. less than .15 wt% Cl. The metal composite is prepared by mixing particles of the metal matrix with particulate fused yttria to form a mixture and heating the mixture at elevated temperature and pressure to consolidate the particles and form a metal reinforced composite.
摘要:
A thermally conductive diamond metal composite comprising 5 to 80 volume percent diamond particles having a particle size ranging from about 1 to 50 µm and a metal matrix comprising a thermally conductive metal. Preferrably, a fine metal powder having particle size below 53 microns is utilized as the source for the metal matrix.
