Nanoindentation, also named depth-sensing indentation or instrumented indentation, is based on the theories of contact mechanics. The test results provide information on elastic modulus, hardness, strain-hardening, cracking, phase transformations, creep, and energy absorption (Fischer-Cripps, 2004).This technique is widely used in the characterization of …

Hardness. Hardness is typically measured on the Rockwell C scale (HRC). Higher hardness generally means better edge retention but can reduce toughness. CPM CruWear: Achieves a maximum hardness of around 63-65 HRC after optimal heat treatment. CPM M4: Can reach up to 64-66 HRC with proper heat treatment but at the cost of reduced toughness.

The crystal layers in rectorite could be expected to have similar values to the crystal layers in muscovite. Yet the dramatically lower values for indentation modulus and hardness of rectorite, as compared to the values for muscovite, testify to the mechanical importance of interlayer water molecules and other atoms present in rectorite.
