英文摘要	The strength and equation of state of molybdenum triboride have been determined under nonhydrostatic compression up to 80gpa, using an angle-dispersive radial x-ray diffraction technique in a diamond anvil cell (dac). the rxd data yield a bulk modulus and its pressure derivative as k-0 = 342(6)gpa with k-0' = 2.11(17) at psi = 54.7 degrees. analysis of diffraction data using the strain theory indicates that the ratio of differential stress to shear modulus (t/g) ranges from 0.002 to 0.050 at pressures of 4-80gpa. together with theoretical results on the high pressure shear modulus, our results here show that molybdenum triboride sample under uniaxial compression can support a differential stress of similar to 10gpa when it started to yield with plastic deformation at similar to 30gpa. in addition, we draw a conclusion that mob3 is not a superhard material but a hard material.
