Microstructural Characterization of Ni-Al Alloyed Layer under Laser Rapid Solidification Condition
Nickel layer electroless deposited on aluminum substrate was alloyed by Nd-YAG pulsed laser irradiation. Solidification microstructure was characterized through cross section, showing typical microstructure that were located in upper and middle melted zone and interface of melted pool and substrate, respectively. The microstructure was analyzed by transmission electron microscopy (TEM). Followed by the observations, the eutectic growth process was analyzed.
