Diffusional Analysis in Al-Ni Cold Rolled Strip during Annealing Process

Abstract:

Diffusion annealing experiments in Al-Ni cold rolled strip was conducted in nitrogen protection. The characterization of diffusion layers between pure Al and pure Ni metals has been analyzed. The analysis results show that the diffusion layers would be composed of solid-solution of Al in Ni marked as Ni (Al), Ni3Al and Ni5Al3 compounds. During diffusion processing, the diffusion speed of Al to Ni was faster than that of Ni to Al. This implied a possibility to form chemical connection of Al-Ni by solid-solution without intermetallic compounds formation to obtain good mechanical and electric properties through optimizing annealing temperature and holding time.
