摘　　要：对不同挤压变形钨合金材料进行了穿甲模拟靶试试验研究,并通过与真空热处理态、不同旋锻变形态钨合金材料的模拟弹靶试进行对比分析,得出如下重要结论:(1)液力挤压大幅度提高了钨合金材料的抗拉强度、屈服强度;(2)液力挤压钨合金材料的模拟弹穿深明显高于真空热处理态、旋锻变形态;(3)经8发模拟穿甲弹试验表明,尽管液力挤压态钨合金材料的强度很高,但在射击过程中无断弹、碎弹现象。Experimentation and research on penetrating simulation ballistic body were proceedecl by the clifferent hydraulic extruding tungsten alloys, and compared with the vacuum states and circle forging states. The important conclusions as follows： （1） the tension strength and yield strength of hydraulic extruding were largely improved; （2） the penetrating armor depth of simulation ballistic body extruded tungsten alloy materials distinctly overmatched the vacuum heat treatment states and circle forging states; （3） the results of 8 simulation ballistic bodyies showed that it was not broken and crashed during shooting process although the tungsten alloys extruded have highly strength.
