The crystallization kinetics of an undercooled Pd40Cu30Ni10P20 melt were examined for samples of different weights. The thermal stability of the melt was strongly influenced by the sample weight. This phenomenon is interpreted under the assumption that the nucleation event of a crystalline phase is dominated by statistical probability. It is, therefore, concluded that the thermal stability and the critical quenching rate Rc of the supercooled melt are dependent on sample weight. The origin for the high glass-forming ability for the Pd40Cu30Ni10P20 alloy is also discussed in view of thermodynamic features of the primary precipitating nucleus.
