Yielding and flow behavior of Mo sub 5 Si sub 3 single crystals

Deformation behavior of Mo sub 5 Si sub 3 was studied using single crystals under compression. It was found that yielding and flow behavior were strongly dependent on temperature, strain rate and crystal orientation. A stress exponent and an activation enthalpy of lower yield stresses were estimated...

Description
Summary:Deformation behavior of Mo sub 5 Si sub 3 was studied using single crystals under compression. It was found that yielding and flow behavior were strongly dependent on temperature, strain rate and crystal orientation. A stress exponent and an activation enthalpy of lower yield stresses were estimated to be approx =6 and 4.5 eV, respectively.
