On the Application of Vickers Micro Hardness Testing to Isotactic Polypropylene. [PDF]
Polymers (Basel), 2022 Hardness is a useful measure of a material’s resistance to permanent indentation; but for viscoelastic polymers, hardness data are highly dependent on the test type and the parameter set chosen. Vickers microhardness testing is used to leave small indents (<150 µm) and is shown to be applicable to polymers.

A study of size effect in micro-forming with micro-hardness tests [PDF]
Journal of Materials Processing Technology, 2006 Abstract The size effect on the material properties in the micro-forming is examined in the present study using both the micro-hardness test and the finite element analysis. The measured hardness indicates that the hardness decreases as the dimension of the specimen is downscaled to a small size.
