摘要
针对20多年来镍基合金中硼微合金化的研究,介绍了微量硼在其晶界上的偏聚析出机制,重点综述并讨论了微量硼在晶界上的偏聚析出行为。
Based on the research status of boron microalloyed nickel-based alloys over the past two decades, in- tensive attention is paid to the mechanism of segregation and precipitation of boron in grain boundary. In addition, grain boundary segregation and precipitation behavior of trace boron are summarized and discussed.
