When an alloy is cooled into the miscibility gap in the liquid state,liquid-liquid decomposition takes place.There is an increasing interest in synthesizing composites containing very fine minority phase particles by using the liquid-liquid phase transformation.A lot of experiments have been carried out both under microgravity conditions and on earth to investigate the solidification mechanism of this kind of alloys.But up to date,the details of the microstructure evolution during the liquid-liquid decomposition remain an unsolved scientific problem.
