Abstract:

The newest development about the recent research of high specific gravity tungsten alloy material strengthening technology was introduced comprehensively and synthetically. According to the process of tungsten alloy material,it is divided into two courses:pre-strengthening and post-strengthening. In the first post-strengthening part,some strengthening technologies, such as grain refinement,element adding,sintering and metallurgical structure strengthening technology were introduced briefly. Also,as a keynote,some major deformation strengthen crafts on tungsten alloy were described in detail in the second post-strengthening part and the crafts included rotating forging, rolling, hot extrusion and hydrostatic extrusion technology. The theory of them was analyzed and studied. In addition, the strengthening technology of HIP and strengthening theory was introduced.
