摘要：
The experiment has proved that in silicon bearing heat-resisting nodular iron some amount of hydrogen are spontaneously dissolved into α-Fe with silicon, and the segregation of hydrogen on crystal plane causes brittleness. The interaction effect of silicon brittleness and hydrogen brittleness is the essence of brittle cracking of such nodular iron. Brittle cracking often occurs at the interface between nodular graphite and matrix where hydrogen is enriched.
