Abstract
ⶠFirstly, special “halo” microstructure caused by interdiffusion of Al and Si atoms appears on the treated surface. ⶠSecondly, the metastable structures, such as supersaturated solid solution of Al, nano-silicon and subgrain, are formed on the modified surface. ⶠThirdly, the microhardness of “halo” presents a gradient change after 15 pulses, and the hardness of remelted layer of 25-pulsed sample is higher than of the matrix.
