Investigation of partially crystalline metallic glass Fe₃₈Ni₃₆B₁₈Si₈

Abstract Partially crystalline metallic glass Fe38Ni36B18Si8 was produced by rapidly solidifying in the form of ribbon. Chemical composition and homogeneity of the sample were determined using Scanning Electron Microscopy, equipped with energy-dispersive X-ray spectroscopy. The diffractogram exhibits a characteristic diffuse halo pattern superimposed with crystalline peaks, indicating existence of crystalline phases. The crystallization kinetics in non-isothermal conditions was studied by Differential Scanning Calorimetry. The electrical resistivity and the dimensions of samples Fe38Ni36B18Si8 were measured at room temperature. The temperature dependence of electrical resistivity was studied from 80 to 273 K. The measurements have shown a positive coefficient of electrical resistivity.
