抄録

  It is reported that La-Al-Transition Metal alloys have high undercooled melt formation and high bulk amorphous formation ability by using rapid solidification process.<br>    We have examined the undercooling solidification and remarkable nucleation control behavior with adding SiC whisker by using containerless process.<br>    In this study, we investigated the undercooling, nucleation behavior and bulk amorphous formation for La₅₅Al₂₅Cu₁₀Ni₅Co₅ samples and samples with SiC whisker addition which are levitated and solidified by using the new gas jet flow and high cooling type electromagnetic levitation system. Therefore, the nucleation was controlled and the high undercooling degree, ΔT(=0.22~0.28T_m), was obtained with increasing SiC whisker addition. In addition, the bulk amorphous sample, φ7 mm sphere, was obtained at the cooling rate of levitating melt and solidification, about 100 K/s, for sample with 0.2% or more SiC whisker addition.<br>
