    摘要: A composition of a porous body for use as biomaterial according to the present invention is produced by adding Al (aluminum) in the amount of 0.1 to 3.0 atomic weight % to a porous composition consisting of titanium, nickel, iron and molybdenum, and it promotes the growth of living tissue and cells into pores. By the addition of Al to Ni, Ti, Fe and Mo, the temperature of formation of the liquid phase is lowered, and thus the diffusion of the constitutional elements of the composition is promoted, and the uniform distribution of the constitutional elements increases. As a result, the proportion of micropores in the porous body becomes increased to the extent that the distribution of micropores having the size in the range of 10null2null10 microns is more than 5% in the metal bridge.

    摘要: A method for producing fine or ultra fine powder particles comprising mixing a metal alkoxide with a non-metallic hydride in an organic solvent, agitating the mixed solution, and then burning the mixed solution. The burning process comprises igniting the solution directly or burning the solution in situ. A self-sustaining flame will result. When the precursor solution burns, the metallic compound will be co-fired with the organic solvent. As a result, fine or ultra fine particles of mixed metal will burst from the flame, or thrust through the flame and be synthesized.

    摘要: An apparatus and method of producing dense, near net shape components of advanced materials such as intermetallics, ceramics, and their composites. The method consists of two major steps combined into one. First step includes the preparation of semi-solid or liquid materials by means of combustion synthesis or self-propagating high-temperature synthesis. The second step includes the densification and near net shape forming of such combustion products by semi-solid metalworking or die casting techniques. The combination of combustion synthesis and semi-solid metalworking or die casting techniques provides a low cost, fast production method for many articles made of high temperature materials such as intermetallics, ceramics, and their composites.
