Solidification behavior of LaFe13-x-ySixCoy Valloys was investigated by induction melting. Phase formation and structure in induction melted LaFe13-x-ySixCoy alloys have been investigated by means of power X-ray diffraction analysis （XRD） and scanning electron microscopy （SEM）. The results have shown that the phase is a peritectic phase. The solidification behavior of LaFe13-x-ySixCoy alloys is greatly affected by overcooling and amount of Si and Co additive. La（Fe,Co and Si ）13 phase occurs with x=1. 5 and overcooling temperature T≥40 K,as is interpreted by the classical nucleation theory.
