Abstract

The solidification behaviour and resultant microstructures of bulk glass forming ferrous (Fe60Co8Zr10Mo 5W2B15) and non-ferrous (Zr65Al 10Ni10Cu15) alloy systems have been investigated. It was shown that the suppression of the eutectic reaction during solidification ultimately leads to the formation of an amorphous structure. The characteristic DSC pattern of melting involving a sequence of eutectic and peritectic like reactions with a high magnitude of reaction enthalpies ratio (ΔHp/ΔHe), appear to be essential parameters for high bulk glass forming ability. © 2004 Elsevier B.V.
