摘要
包晶合金定向凝固过程中的相和组织选择是一个复杂的过程。综述了包晶合金定向凝固中的低速带状与共生生长组织的实验和理论研究情况及其进展。讨论了低速带状与共生生长组织的关系,说明两者并非孤立存在,带状向耦合生长组织的转变可能源于某一临界成分。
Phase and structure selection of peritectic alloys under directional soildification is a complex problem. Developments of both theoretical and experimental results of low velocity coupled growth and banded structure of peritectic alloy are reviewed. Relationship between banded structure and coupled structure of peritectic alloy is also discussed. Transition from banded structure to coupled structure is probably affected by a critical composition. In the meantime, trends of some areas about peritectic alloys are presented.
