Hardness and Hardness Determination in Silicon Carbide

01.01.2005· Hardness nuers were measured by indentation with Knoop and Vickers diamonds in the load range from 0.245 N to 4.9 N on a Leitz Miniload-2 tester. At loads over 0.98 N hardness decreased with increasing load. Highest values for Knoop and Vickers hardness at constant load were obtained with the SiC single crystals. In most cases it was found that Vickers hardness is higher than Knoop hardness
