【摘要】 用定向凝固液淬法制备了具有各种石墨形态的铸铁试样，借助于金相显微镜、ＳＥＭ等对其进行了观察分析，发现界面推进速度对固液界面形貌及石墨形态均有影响，并考察了在界面推进速度相同的情况下，微量元素铈、硫对石墨形态的影响．更多还原

【Abstract】 The cast iron models of various graphite form were prepared by the way of directional solidification liquid?quenching.It was analyzed with the metallographical microscope,SEM and so on.The results show that the shape of the boundary and graphite are affected by the pushing velocity and minute element.更多还原
