Abstract
The results of measurement of the Vickers microhardness (H-v) of the (100), (010), and (001) faces of the nonlinear optical (NLO) crystal L-arginine h ydrochloride monohydrate (LAHCI) have been reported. It was observed that t he microhardnesses of the three crystal planes decrease with the increase o f applied load, and the hardness profile is different for different planes. The proportional specimen-resistance (PSR) model of Li and Bradt is used t o explain the microhardness behavior of LAHC1. The indentation work-hardeni ng coefficients (n) for three planes were found to be greater than 1.8, and this indicates that LAHCI is a soft crystal.
