Effect of compressive deformation on thermal and corrosive properties of Zr61.7Al8Ni13Cu17Sn0.3 bulk metallic glass
Abstract
The effect of compressive deformation on thermal stability and corrosive property of Zr61.7Al8Ni13Cu17Sn0.3 bulk metallic glass with a strain of 80% was investigated in this work. The corresponding thermal stability is found to decrease after deformation and this can probably be attributed to the reduction of the viscosity and the increase of the Gibbs free energy after compressive deformation. In addition, the corrosion current density increases and this suggests that the corrosion resistance decreases for the deformed sample in comparison with the as-cast sample.
