摘      要：The effect of rare earth addition on thermal stability of Fe_(50−x)Cr_(15)Mo_(14)C_(15)B_(6)M_(x)(x=0,2 and M=Y,Gd)is *** and structural properties are measured using differential scanning calorimetry and x-ray diffraction,*** microstructure is observed by using a scanning electron microscope,and chemical composition is checked by energy dispersive spectroscopy *** effect of high temperature on the isothermal crystallization of Fe_(50−x)Cr_(15)Mo_(14)C_(15)B_(6)M_(x)(x=0,2 and M=Y,Gd)bulk metallic glass and ribbons is investigated by high-temperature x-ray *** is found that the crystallization behavior of Fe_(50−x)Cr_(15)Mo_(14)C_(15)B_(6)M_(x)(x=0,2 and M=Y,Gd)bulk metallic glass strongly depends on the annealing *** different crystallization behavior is believed to be due to the different structures that the metallic glass possesses at different temperatures.
