Abstract
Aluminum powder, neutron absorber, and third particle composed of oxide, nitride, carbide or boride are mixed, and preformed by cold isostatic pressing (CIP). Successively, by canning the preformed material, this preformed material is sintered by hot isostatic pressing (HIP). After sintering, the can outside and end face are machined by grinding, and the billet is taken out. Square pipes are formed by extruding this billet.
Claims27
An aluminum composite powder obtained by employing mechanical alloying, and dispersing neutron absorber, and third particle composed of oxide, nitride, carbide or boride ground by mechanical alloying in aluminum matrix.
A manufacturing method of aluminum composite powder comprising the steps of:
- mixing aluminum powder as matrix material, neutron absorber, and third particle composed of oxide, nitride, carbide or boride;
- and
- dispersing the ground neutron absorber and third particle in the aluminum matrix by mechanical alloying of the mixed powder.
An aluminum composite material characterized by containing neutron absorber and third element composed of oxide, nitride, carbide or boride, in aluminum matrix.
