提出了钨合金的组织结构模型．在此基础上通过有限元法对钨合金拉伸变形时组织结构中的应力分布及其变化规律进行了计算机数值模拟研究．结果表明：钨合金拉伸变形时拉伸方向最大正应力和最大Mises应力区域在钨颗粒相中，同时钨颗粒还将受到垂直于拉伸方向的压应力；最大剪切应力分布在粘结相中，随拉伸变形增加，粘结相最先进入塑性状态；由于粘结相的塑性变形，钨合金中应力不断重组，应力逐渐在钨颗粒中集中．
Proposed a tungsten alloy structure model. On the basis of this, the stress distribution in the structure of Tungsten alloy during tensile deformation and its variation are studied by computer numerical simulation. The results show that the maximum normal stress and the maximum Mises stress in the tensile direction of tungsten alloy are in the tungsten particle phase and the tungsten particles are also subjected to compressive stress perpendicular to the tensile direction. The maximum shear stress is distributed in the binder phase , As the tensile deformation increases, the binder phase first enters the plastic state; due to the plastic deformation of the binder phase, the stress in the tungsten alloy is continuously reorganized, and the stress gradually concentrates in the tungsten particles.
