Abstract

Effects of partial substitutions of Co for Fe on the glass forming ability (GFA), mechanical and magnetic properties have been studied aiming at commercial magnetic and structural applications of bulk metallic glasses Fe_68.7-xC_7.0Si_3.3B_5.5P_8.7Cr_2.3Mo_2.5Al_2.0Co_x (x=0-10). Fully amorphous rods of 6 mm in diameter exhibiting fracture stress (σ_f) approaching 3.4 GPa and plastic strain (ε_p) of about 0.5% can be prepared through the replacement of 1-2 at% Fe by Co. Enhancement in GFA is attributed to the suppression of primary phase α-Fe with the optimum Co additions. Magnetic properties can be improved by the partial substitution of Co for Fe in the amount of 5 at% leading to the formation of amorphous ribbon with a saturation magnetization value of 0.85 T and a coercive force value of 11.5 A/m.
