Abstract
Based on the combination of experiments and numerical simulations, the plastic properties of a 91%(mass fraction, the same below) refined particle tungsten alloy were investigated. The results show that refined tungsten alloy has a strain rate effect and the yield strength increases with the increase of strain rate. The temperature effect, size effect and crystal orientation effect appear obviously in the nano-tungsten alloy materials. By comparing the numerical results and the experimental results, the conclusion obtained is two methods are in good agreement.The accurateness of this molecular dynamic simulation and the reliability of the fitted power law formula at high strain rate state are proved.
