Abstract:

In-situ Ni-Al Intermetallic compound reinforced aluminum matrix was fabricated by powder metallurgy technology. By the use of Optical Microscopy and Scanning Electron Microscopy (SEM), microstructure, thermodynamics and dynamics was investigated in this paper. The results show that in-situ Ni-Al/Al composite consists of primary α-Al phase and NiAl reinforcement. In addition, Ni-Al/Al system dynamics model was established. From the dynamics model, the main factors affecting the reaction rate of the system are heating temperature, nickel content and the diffusion layer thickness δ. During the temperature of 400~460°C, NiAl intermetallic compound can be obtained.
