Abstract

Microhardness studies have been carried out to study the effect of impurities on hardness in term of the deformation behavior. The present communication compares the variation of microhardness with load of pure and oxidized carbazole single crystals. Plot is observer that there are four humps for the pure carbazole crystal around 20 gm, 40 gm, 60 gm, and 80 gm. Whereas in the case of oxidized carbazole a small humps around 50 gm and three other prominent humps at 60 gm, 75 gm and 90 mg are observed. These humps are due to cause of slip on the different crystallography planes and the shift in the humps postions is due to the impurities hindering the slip is taking place at law loads.
