| Yhteenveto: | Заглавие с титульного листа Электронная версия печатной публикации The results of measurements of acoustic wave speeds and elasticity modules of metal ceramic alloys on the basis of tungsten monocarbide in temperature range of 100...295 K as well as amplitude dependences of internal friction at temperatures 140...295 K and after γ-irradiation (60Со, 1,25 MeV, 5.103 and 105 Gy) have been given. It was shown that elasticity modules of alloys decrease monotonously at increase of cobalt concentration. Radiation influence stimulates the processes complicating movement of grain boundary dislocations in alloys. Representation of these alloys in the form of isotropic mixes of anisotropic phases describes qualitatively correctly the dependence of elasticity modules on structure. The resulted experimental and calculated values of elasticity modules may be used for estimation of elastic and strength properties of these alloys |
