grain boundary precipitates

The law of variation of grain boundary precipitation with the changing of processing factors and chemical compositions of three strengthened superallys was studied with the application of extracted carbon replica technique on grain surfaces.

用晶界萃取碳复型技术研究了三种不同强化程度高温合金晶界沉淀随工艺因素和成分的变化规律,探讨了晶粒尺寸、晶界沉淀与冲击韧性的关系。
