In this paper, the dynamic compressing experiments for the matrix material of the tungsten alloys which have been three different deforming(0%、 32.6%、 44.6%) processed have been performed by the experimental technology of separated Hopkinson pressure bar and many accurate datum have been obtained. Also the three materials have been compared with each other and analyzed. The results show that the optimized values are in a certain range to optimize the materials by changing their deforming technology. The parameters of constitutive model of Johnson-Cook have been fitted based on the datum. Then proceed to the next step, adiabatic shear band of these three matrix materials has been analyzed with finite element method. The result shows that the relations between stress and strain are different because of the differences of technical process of the three materials, but they are in great commonness in the material experiment and in great coherence in the distribution of time and space, which can been seen from the space distributing figures of plastic strain.
