In this patent, we have developed the process of coating of nickel (Ni) plating layer uniformly over fine aluminum (Al) and nickel powders and particles or whisker of reinforcement by using electroless plating technique to form Ni-Al, Ni-Ni and Ni-reinforcement composite powders. Then through compacting, sintering, rolling and homogenizing of traditional powder metallurgy method to manufacture the high density final products of Ni3Al intermetallic compound. This patent also demonstrates excellent room temperature mechanical properties of CPM final product. This method does not need those HIP, HP expansive powder metallurgy facilities and the dimension of products won't be limited by HIP or HP equipment. This method has the capability to produce large size products with low cost, better efficiency and fast speed.
