It has been shown that particles of M6C in Cr-Mo-V low alloys steels can influence phosphorus grain boundary segregation in a similar manner to Laves phase particles in 12CrMoV steel. The influence of these particles arises from their ability to dissolve non-metallic elements such as phosphorus and silicon. As phosphorus is progressively segregated to the grain boundaries during prolonged ageing, the precipitation of M6C particles leads to an anomalous decrease in the phosphorus grain boundary concentration as the ageing time is extended.
