图7 CoCrNi、(CoCrNi)88Fe10Si1B1和(CoCrNi)75Fe21Si2B2合金的TEM分析[66]

Fig.7 TEM images of the CoCrNi (a), (CoCrNi)88Fe10Si1B1 (b), and (CoCrNi)75Fe21Si2B2 (c) alloys[66] showing that the structure changes from nanocrystalline to crystal-glass dual-phase with increasing Si and B contents in the CoCrNi-Fe-Si-B alloys, and plane-view ABF-STEM image shows ≈ 1 nm-thick amorphous phase (brighter regions) appearing at triple points and along some grain boundaries (d)
