Investigation of Mechanical Properties and Plastic Deformation Behavior of (Ti45Cu40Zr10Ni5)‎100−xAl x Metallic Glasses by Nanoindentation

الملخص EN

The effect of Al addition on mechanical properties and plastic deformation behavior of (Ti45Cu40Zr10Ni5)100−xAl x (x = 0, 2, 4, 6 and 8) amorphous alloy ribbons have been investigated by nanoindentation.

The hardness and elastic modulus do not simply increase with the increase of Al content.

The alloy with 8 at.% Al exhibits the highest hardness and elastic modulus.

The serrations or pop-in events are strongly dependent on the loading rate and alloy composition.
