Analysis of Melt Temperature Effects on Rapid Solidification of Al Alloy Structure

Abstract:

The alloys Al₈₈Co₄Y₈, Al₈₈Ni₄Y₈, Al₈₇Ni₁₀Ce₃ and Al₈₅Ni₁₀Ce₅ were heated and mixed by using intermediate frequency furnace. By controlling different melt superheat tempratures, a series of thin strip alloy samples were prepared by single roller spinning quenching method. The X-ray diffraction (XRD) results show that melt temperatures have different effects on the amorphous structure formation of Al-(Co,Ni)-(Y,Ce) alloy. In addition The glass forming ability of Al-based amorphous alloy prepared by thermal analysis was analyzed. Experiments results indicate that the higher the melt temperature of Al₈₈Co₄Y₈ alloy, the easier the formation of the crystallization phase.
