Effect of Ar+ treatment on thermal stability and micromechanical properties of Fe75Mo5Si6B14 amorphous alloy

The amorphous alloy Fe 75 Mo 5 Si 6 B 14 has been shown for investigations. It is shown that the interval of thermal stability has expanded by 80-120 K after ion treatment of the amorphous alloy for 5-25 min, respectively. When Fe 75 Mo 5 Si 6 B 14 amorphous alloy treated with Ar + for (5-10) minute...

Description
Summary:The amorphous alloy Fe 75 Mo 5 Si 6 B 14 has been shown for investigations. It is shown that the interval of thermal stability has expanded by 80-120 K after ion treatment of the amorphous alloy for 5-25 min, respectively. When Fe 75 Mo 5 Si 6 B 14 amorphous alloy treated with Ar + for (5-10) minutes, the relative change in microhardness is of 2.5%-4%, that is, it is within the experimental error of 5%. When the alloy treated for 15-25 min, the microhardness decreases by 7%-13%, that is, a plasticization effect is observed. The effects of expansion of the thermal stability interval and plasticization of an amorphous alloy can be explained by the dissolution of frozen centers of crystallization. This fact is confirmed also by SEM studies of the surface morphology of the amorphous alloy.
