A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

The present invention relates to a method for producing a component of a γ-TiAl alloy, in which, in a first step, a forging blank made of a γ-TiAl alloy is built up from a powder material by an additive method, and subsequently, in a second step, the forging blank is reshaped into a semi-finished product, wherein the degree of reshaping over the entire forging blank is high enough that, in a third step, the structure is recrystallized during a heat treatment. In addition, the invention relates to a component produced therefrom.

A magnesium-based thermoelectric conversion material includes a first layer formed of Mg.sub.2Si and a second layer formed of Mg.sub.2Si.sub.xSn.sub.1-x (here, x is equal to or greater than 0 and less than 1), in which the first layer and the second layer are directly joined to each other, and within a junction surface with the first layer and in the vicinity of the junction surface, the second layer has a tin concentration transition region in which a tin concentration increases as a distance from the junction surface increases. The junction layer is regarded as a site in which a tin concentration is found to be equal to or lower than a detection limit by the measurement performed using EDX.
