In Situ Determination of Micro-properties of Tungsten Alloy Matrix

  • To obtain the micro-properties of tungsten alloy matrix,its micro-hardness and micro-elastic modulus were measured by nano-indentation experiments.The micro-yield strength,micro-hardening modulus,elastoplastic parameters and the stress-strain relationship of the tungsten alloy matrix were determined using the finite element method,a hardening model,and the load-displacement relationship obtained from nano-indentation experiments.Analyses of the results show that the composition of the alloy and deformation strengthening are two basic factors to influence the micro-properties of tungsten alloy matrix.The micro-hardness and micro-yield strength of the alloy matrix increase with an increase in deformation or in the concentration of tungsten.
