Abstract
A metal-based composite material is formed by impregnating a matrix metal of Al or Al alloy into ores of a porous preform of a hydrogenatable metal having a metal hydride in at least a part of its surface.
Claims18
A metal-based composite material comprising:
- a preform comprising a porous hydrogenatable metal selected from at least one of Ti, Fe, Co, Al, Cu, Mg, W, Mn, Cr, or Be, and having a hydrogen solubility at 500-600° C. of 0.1-10 cm3/100 g of metal;
- a metal hydride in at least part of the preform surface;
- and
- a matrix metal impregnating pores of the preform, the matrix metal comprising Al or an Al alloy containing at least one of Mg, Cu, or Si.
A method of producing a metal-based composite material, which comprises using a hydrogenatable metal selected from Ti Fe, Co, Al, Cu, Mg, W, Mn, Cr, Be and an alloy thereof as a starting material, shaping it into a porous body having a porosity of 20-80 vol %, forming a metal hydride on at least a part of the porous body to produce a porous preform, immersing the preform in a matrix metal bath of Al or an Al alloy containing Mg, Cu and/or Si held in an air atmosphere under no pressure to impregnate the matrix metal into the preform.
