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 (Fe0.58Co0.42)73Mo17-xCrxZr10(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 TgTxTp move towards to the lower temperature regions, but the supercooled regionsΔTx increases, the GFA of sample is rising. In the bend test, all the amorphous ribbons can be classified asductile.
