英文摘要	Investigations of equation of state, strength and texture of tungsten (w) have been performed under non hydrostatic compression up to 96 gpa using an angle-dispersive radial x-ray diffraction (rxrd) techniques together with the lattice strain theory in a 2-fold paranomic diamond anvil cell (dac) at ambient temperature. the ratio of t/g is found to remain constant above similar to 35 gpa, indicating that the w started to experience macro yield with plastic deformation at this pressure. combined with independent constraints on the high-pressure shear modulus, we found that w sample could support a differential stress of similar to 4.57 gpa when it started to yield with plastic deformation at similar to 35 gpa under uniaxial compression. the differential stress in w ranges from 0.01 gpa to 1.46 gpa with pressure increasing from 6 gpa to 35 gpa and can be described as t = -0.904(136) + 0.154(6)p, where p is the pressure in gpa. a maximum differential stress, as high as similar to 6.46 gpa can be supported by w at the highest pressure of similar to 96 gpa. in addition, we have investigated the texture of w under nonhydrostatic compression up to the highest pressure of 96 gpa using the software package maud (material analysis using diffraction). it is convinced that the plastic deformation due to stress under high pressures is responsible for the development of texture.
