英文摘要	The mechanical properties of pbwo4 (pwo) crystals grown by the vertical bridgman method are systematically investigated using the microindentation technique. in the present work, the vickers microhardness h-v, fracture toughness k-c, yield strength sigma(y) and friability index b-i of pbwo4 crystals are measured. the vickers microhardness h-v on the (100) wafer is about 140 mpa, which means that pwo is a little "soft" scintillator. the anisotropy of mechanical properties is also investigated under a steady load of 0.5 kg. the (100) wafer of the crystal exhibits combined mechanical properties more excellent than those of (111) and (001) wafers, and the values of k-c,k- sigma(y), and b-i are 0.538 mpa.m(1/2), 51.11 kg/mm(2) and 284.96 mu m(-1/2), respectively.
