The results suggest that if Cu layer is too thin, the eutectic substance created from eutecticreaction is little, it can not fill the seam and the areas of joints are empty;
结果表明：铜层过薄，共晶反应生成的液相量太少，未能填满缝隙，接头有空洞出现；

Solidification process of CV graphite iron with the addition of various CV-graphitizing materials and the crystallization behavior of the graphite during the eutecticreaction was clarified.
