Investigation of microscale heterogeneities. a Low-magnification STEM images taken from the cross-section of the Fe50Ni30P13C7 BMG. In order to eliminate any oxide layer and microcrystallinity generally forming on the surface during casting, our investigations were performed at the center region of the specimen (scale bars 2 µm). b Hardness & Reduced Modulus contour plots of 1 mm-sized Fe-BMG disc (the distances are in mm). c Indentation load vs. indentation depth of the corresponding measurements. d The variations in the contact depth, reduced modulus, and hardness (inset) obtained from the nanoindentation tests
