Sm. Vyas et al., MICROHARDNESS STUDIES ON CLEAVAGE PLANES OF SNS AND SNSE SINGLE-CRYSTALS, Indian Journal of Pure & Applied Physics, 33(4), 1995, pp. 191-194
SnS and SnSe single crystals were grown by the Bridgeman-Stockbarger m
ethod. Vickers hardness measurements were carried out on the cleavage
surfaces of the crystals. The load dependence of hardness was studied
and compared for the two crystals. The bulk hardnesses of the crystals
have been found to be about 950 and 980 MPa, respectively. The measur
ements were also carried out on samples quenched from various high tem
peratures. The quench-hardening indices have been evaluated and the re
sults are reported.
