Abstract

The critical cooling rate for glass formation was measured for an Fe-based easy glass forming alloy using a wedge casting technique combined with direct temperature measurements and finite element heat transfer analysis. For an alloy with a nominal composition Fe₄₈Cr₁₅Mo₁₄Y₂C₁₅B₆, the critical cooling rate was measured to be in the range 140-190 K/s. The low critical cooling rate indicates that this alloy may be suitable for use in thermal spray processes. The main crystalline phase competing with glass formation during continuous cooling appears to be a M₂₃C₆ type phase.
