In this work, the effect of Ni addition on the glass forming ability (GFA) of FeMoPCB composite alloy was investigated and the optimal amount of Ni to improve GFA was determined. So, the thermal stability of this alloy with the various percent of nickel was investigated by not only experimental methods including; differential scanning calorimetry, X-ray diffraction, optical microscope and transmission electron microscopy but also computational methods such as α، β، γ and etc. The results of XRD test, TEM showed that in the presence of 10 at.% nickel , the glass-forming ability of this alloy increased, while in the presence of lower or higher percent nickel, different crystalline phases were detected. The presence of crystalline phases was also investigated by microhardness test. Finally, it was found that the results of the computational methods regardless of the experimental results don’t have enough accurate .
