中文摘要
目前正在对二元和三元合金的凝固进行研究,以检查偏析模式并获得界面形态的理论预测。在具有金刚石立方结构的相中加入三元元素诱导孪晶来改变显微组织的研究正在进行中。探索了通道偏析的发展,以确定除金属合金外对其他材料(如碱卤化物或透明有机材料)的影响的普遍性。
英文摘要
Research is being performed on solidification of binary and ternary alloys to examine segregation patterns and obtain theoretical predictions on interfacial morphology. Modification of microstructure by addition of ternary elements to induce twinning in phases having the diamond cubic structure is under investigation. Development of channel segregation is explored to determine the generality of the effect beyond metal alloys to other materials such as alkali halides or transparent organic materials.
