在不同凝固条件下稀土综合变质剂的变质作用研究

Study of Modification of the Carbide in Vanadium White Iron by RE Com plex Modifier

用定向凝固技术研究了稀土综合变质剂在不同凝固条件下对钒白口铁中碳化物球化作用的影响 。

The effect of different solidification conditions on spheroidization of the carbide in vanadium white cast iron modified by RE complex modifier has been investigated using unidirectional solidification technique.And the morphology of the carbide in different zone of the unidirectionally solidified specimen was interpreted.
