Abstract

Bulk glasses are obtained by quenching melts of various compositions. The initial temperature is chosen above the liquidus temperature (T1) of materials assuming that the melt is homogenous. Glassy items are formatted above the glass transition temperature Tg below a crystallization temperature called Tx. First-order transitions at Tx transform melts into composites containing crystals and new glassy phases, melting at temperatures (Tn+) much higher than (T1). These first-order transitions were studied at Caltech Pasadena by cooling and heating a melt of Pt57Cu23P20. A recent model predicting the formation enthalpies of these new composites at Tx and the melting temperatures (Tn+) of glassy fractions is applied to this alloy.
