DEASA is self-undercooled alloy. Help us write another book on this subject and reach those readers. Hypereutectic DEASAs with silicon in range from 13% to 17% exhibit completely self-modified eutectic structure, but are subjected to fully fading upon remelting due to disappearance of undercooling in freezing. DEASAs have high volume of α-Al dendrite that is associated with the high undercooling in freezing. 2558total chapter downloads. Built by scientists, for scientists.

Ge peritectic alloy are undercooled up to 260 K using electromagnetic levitation technique. The growth rate of the primary phase is measured using a capacitance proximity sensor technique. Solidification microstructure is studied as a function of undercooling. The microstructure of samples at low undercoolings consists of a residual primary phase a2, peritectic phase e and inter-dendritic e–b eutectic

In Parts 1 and 2 of this series of articles, it was shown that a range of levitation-melted Fe-Cr-Ni alloys, both hypoeutectic and hypereutectic, all solidified with the hypereutectic phase (bcc) as their primary phase.

In Parts 1 and 2 of this series of articles, it was shown that a range of levitation-melted Fe-Cr-Ni alloys, both hypoeutectic and hypereutectic, all solidified with the hypereutectic phase (bcc) as their primary phase, except for the hypoeutectic alloys at low undercoolings. In this article, the effect of heat extraction on phase formation is studied by chill casting the undercooled alloys before nucleation. Two of the previously studied alloys are examined; one hypoeutectic and the other hypereutectic

The forming mechanism of metastable phase in undercooled Fe-Co alloy was concluded as cooperative effect of competitive -extensive growth-incomplete solid-state.

The forming mechanism of metastable phase in undercooled Fe-Co alloy was concluded as cooperative effect of competitive -extensive growth-incomplete solid-state transformation in this work. With the increase of annealing time, the number and dimension of metastable phase decreased at the same time. Abstract: Metastable phase was observed in as-solidified microstructure of undercooled Fe-Co alloy, provided that the initial undercooling (T) of the melt exceeds the critical value. On this basis, the forming mechanism and stability of metastable phase were investigated.

The liquid-phase separation of Cu-Fe alloy has been experimentally investigated at home and abroad, and the . Therefore, it is imperative to explore the solidification process of Cu-Fe alloy melt in the undercooled state.

The liquid-phase separation of Cu-Fe alloy has been experimentally investigated at home and abroad, and the existence of liquid metastable miscibility gap has been proved. The occurrence of liquid-phase separation greatly weakens the ed properties of Cu-Fe alloy and limits its application.
