PURPOSE: To manufacture a composite material with superior strength and tenacity, by incorporating finely and uniformly prescribed second phase particle in a matrix of a super-rapidly chilled alloy.
CONSTITUTION: When Ni-Si-B contg. alloy or the other alloy is manufactured in an amorphous ribbon state or the like by super-rapidly chilling from its molten metal, fine second phase particles having no compatibility with the alloy are mixed with the molten raw material alloy and chilled rapidly. In the above-described molten alloy to be a matrix, as the second phase particle, at least one kind particle among carbide having ≤1μm diameter such as WC, TiC, NbC; nitride such as NbN, TaN; oxide such as ThO2, Al2O3; boride such as BN, and particle of metal or alloy is mixed, and the mixed molten metal is chilled super-rapidly at a lower temp. than the melting point of the second phase particle by blowing the molten metal to a roll or the like revolving at high speed. AN alloy film or the like consisting of the amorphous matrix in which the second phase particle is dispersed uniformly, and having superior strength and tenacity is manufactured.
