Abstract: A method of manufacturing an Ni--Al intermetallic compound matrix composite comprising steps of a) providing an aluminum powder, b) providing a reinforced material, c) providing a reducing solution containing a reducing agent and nickel ions to be reduced, d) adding the aluminum powder and the reinforced material into the reducing solution, and e) permitting the reducing agent to reduce the nickel ions to be respectively deposited on the aluminum powder and the reinforced material. Such method permits the Ni--Al, Ni--Al+B intermetallic compound matrix composite to be produced inexpensively/efficiently/fastly.

Abstract: A electroless plating method of an Ni--Al intermetallic compound includes steps of a) providing a reducing solution containing a reducing agent and reducing nickel ions, b) adding a proper amount of aluminum powder to the reducing solution, and c) permitting the reducing agent to reduce the reducing nickel ions to be deposited on the aluminum powder. Such electroless plating method permits the Ni--Al compound to be produced inexpensively/efficiently/fastly.

Abstract: A method for manufacturing an intermetallic compound comprises (a) preparing a powder, (b) canning said powder in a tube, (c) executing a first heat treatment to said tube-canned powder, and (d) treating said tube-canned powder for obtaining an intermetallic compound. This invention offers a simple, efficient, and inexpensive method for producing an intermetallic compound possessing excellent mechanical properties.

Abstract: A process for densifying a powder metallurgical product comprising steps of preparing a powdery starting material, pre-sintering the powdery starting material at a relatively low temperature, executing a pore-eliminating process for eliminating pores resulting from the preceding step on the powdery starting material, and sintering the powdery starting material at a relatively high temperature. It is beneficial to produce a product having a large dimension, a desired shape, and excellent mechanical properties, and being appropriate for or capable of suffering any post-treatment.
