Abstract
This article discusses analytical dependences of uniform elongation δp and ratios of yield strength to ultimate strength of metal on parameter of strain strengthening n in the Meyer equation. These dependences are verified experimentally for carbon and pearlitic steels upon determination of n using oblique illumination in a microscope for measurement of indentation diameter. The Meyer equation cannot be applied for some austenite steels because of structural phase transformations in deformed metal under indentation.
