Abstract: Fe_86.38-1.06xW_0.62+0.06xSi₃B_10+x(x=0~22%, mole fraction) alloys were prepared by rapid quenching. It was found that the glass-forming range is 15%~28%B(mole fraction). The experimental results for crystallization temperatures, crystallization phases, heats of crystallization, activation energies and microhardness were presented. The crystallization temperature increases with the increase of microhardness and decreases with the increase of electron concentration. The thermal stability increases first with increasing boron content and decreases later with further increasing boron content, and the most stable case occurs at 23%B(mole fraction).
