摘要	Through the fracture toughness measurements and analyses of fracture morphologies of FeMoSiB nanocrystalline with various grain sizes, the microstructure-fracture resistance relationship has been investigated. It was proposed that low fracture resistance can be attributed to intergranular cracking. Fracture resistance increases with the grain size from 11 to 35 nm. And grain blocks' bridging and interfacial friction are the major toughening mechanism. Fracture resistance will reach a maximum and are expected to fall over at larger grain size due to internal stress induced microcracking. Furthermore, variation of fracture resistance with grain size is proposed to be independent of plastic deformation over the grain size range concerned.
