Effect of Cu on the Microstructure and the Property of Al-Ce-Ni-Cu Amorphous Nanocomposite Materials

Abstract:

Preparing amorphous alloy of Al₈₇Ce₃Ni_10-xCu_x（x=0,1,3,5）with single roller spin quenching technology, after annealing the alloy for 20 minutes at 180 degrees Celsius, 200 degrees Celsius, 220 degrees Celsius and 240 degrees Celsius, and then the nanocomposites can be obtained. he microhardness of amorphous nano-composite materials are measured .The microstructure, grain size of , thermal stability, midrohardness are related with the annealing temperature and the composition of alloy, and studying the relationship between them by X-ray diffraction (XRD) and differential scanning calorimetry (DSC).The present results indicated that with the increase of the content of Cu, the grain size of decreases, the increasing of the microhardness is due to the grain refinement: with the increase of the content of Cu, precipitation temperature of moves to low, which is helpful for the precipitation of phase.
