Përmbledhja	Vickers Hardness testing is a mechanical characterization technique for determining material hardness by pressing a diamond pyramid indenter into a material surface under controlled load and measuring the resulting indent dimensions. Invented by Smith and Sandland in 1922, Vickers hardness is applicable across an enormous hardness range (1-2000 HV) using the same indenter geometry at different loads. It is the most versatile hardness test, widely used in materials science, metallurgy, and quality control for assessing material strength and comparing alloy performance.	Nanoindentation, or instrumented indentation, is a technique for measuring the hardness and elastic modulus of materials by pressing a hard probe into a sample surface and continuously recording load and penetration depth. Developed by Oliver and Pharr in 1992, nanoindentation enables measurement of mechanical properties of thin films, small volumes, and nanoscale structures with spatial resolution approaching micrometers. It is the standard tool in materials science for characterizing coatings, interfaces, and mechanical properties at the submicron scale.
