摘要:
An electronic device comprising at least one heat-generating electronic component and a passive electronic component in association with the heat generating component. The passive component comprises a porous preform of green silicon carbide or polygranular graphite, and a metal filling the porosities of the preform which can be aluminum, an aluminum alloy, magnesium or a magnesium alloy. The preform forms about 50 to 90% by volume of the passive component.

摘要:
The invention is directed to microcrystalline Al-based alloys produced by annealing an alloy formed initially in a substantially amorphous state by rapid solidification (about 10.sup.4 K/sec) and having a composition consisting essentially of, in atomic %:from 5 to 30% Sifrom 11 to 22% Niwherein the Ni may be partially substituted by Fe up to 10%, by V or B up to 5 atomic % each, or totally substituted by Mn up to 22 atomic %, and wherein Fe+Ni+Si.ltoreq.42%. In the microcrystalline state, in the vicinity of the first crystallization peak, there is a metastable hexagonal phase whose crystalline parameters are about a=0.661 nm and c=0.378 nm.
