What are the Key Parameters Measured in Nanoindentation?
Some of the critical parameters measured in nanoindentation include:
Hardness: Defined as the resistance of a material to deformation, hardness is calculated from the maximum load divided by the contact area of the indentation. Elastic Modulus: This parameter indicates the material's ability to deform elastically (i.e., return to its original shape after the load is removed). It is derived from the slope of the unloading curve in the load-displacement data. Fracture Toughness: This property measures a material's ability to resist crack propagation and can be determined using specific indentation techniques.
