Effects of Cr Substitution of Mo on the Formation and Mechanical Properties of FeCoMoCrZr Amorphous Alloys

Abstract:

The melt-spun method, X-ray diffractometer (XRD), differential scanning calorimeter (DSC),vickers microhardness measurement and bend test were adopted to study the effects of Cr substitution of Mo on the glass forming ability (GFA), thermal stabilities and mechanical properties of (Fe_0.58Co_0.42)₇₃Mo_17-xCr_xZr₁₀(x=0,3,6,9,12,17at%) ribbons. The results show that when x ranges from 9~17, the ribbons are in an amorphous state. With increasing the Cr content, all the characteristic temperatures including T_gT_xT_p move towards to the lower temperature regions, but the supercooled regionsΔT_x increases, the GFA of sample is rising. In the bend test, all the amorphous ribbons can be classified asductile.
