摘要：
Results of indentation-induced microhardness and fracture studies on (110) and (001) planes of flux-grown DyFeO3 single crystals, using a Vickers hardness tester, in the applied toad range of 10 to 100 g, are presented. The hardness VHN is unaffected by variation in the indentation time, but is observed to be dependent on applied load. The hardness results and the indentation-induced cracking yields the values of the yield strength, fracture toughness and brittleness index for (110) and (001) planes of DyFeO3 crystals.
