The depth dependence of the indentation hardness, i.e., size effect (ISE), was manifested as an increase or decrease in hardness when penetration decreases, which observed by previous experiments. Most scholars believe it is generated strain gradient. However, additional opinions argue that other factors, similar to gradient, can also contribute ISE. Importantly, if such ISE occurs experiment, ...
