摘要：
Grain boundary engineering (GBE) was employed to control the precipitation behaviour of Hastelloy-X alloy. The precipitate characteristics and thermal stability of grain boundary character distribution (GBCD) were investigated by aging at 850 degrees C. M6C carbides and mu phases were observed in the matrix and on grain boundaries, respectively. It revealed that the formation of mu phase was closely related to the grain boundary structure. GBCD effectively suppressed the nucleation and coarsening of mu phases on the grain boundaries. Owing to the Mo depletion in the vicinity of random grain boundary, the formation of the precipitates was inhibited on the adjacent grain boundaries. The thermal stability of the GBE-optimised microstructure was confirmed at 850 degrees C for 720 h without significant microstructural degradation.
