Indentation and Friction of Cu44Zr43Al10Nb3 Bulk Metallic Glasses on nano-scale
Indentation and sliding friction of the as-cast, the relaxed and the crystallized Cu44Zr43Al10Nb3 bulk metallic glass (BMG) are investigated on nano-scale by nanoindentation. The depth, the width and the morphology of the scratches formed by the tip of the nanoindentor are different, which reflect the differences in structure, not only between the glassy and the crystallized states but also between the two glassy states, the as-cast and the relaxed. The coefficient of sliding friction of Cu44Zr43Al10Nb3 BMG is increased with increasing the load, and it is maximal for annealed at 683K. Improved plastic deformability is found for the relaxed one.
