wcu的音标

After liquid phase sintering, the WCu composites have been deformed by hot hydrostatic extrusion and subsequent hot extrusion, during which the plastic deformation of tungsten particle is not obvious.

通过对W-40wt%Cu液相烧结坯进行一次热静液挤压和后续的热挤压变形的实验，发现钨铜材料在一次挤压和二次挤压后，其钨颗粒并没有明显的大的塑性变形。

WCu composites have been used widely in the fields of electrical materials 、 electron 、 war industry and spaceflight due to their high strength and hardness, good electrical and erosion resistance.

W-Cu复合材料具有良好的导电性、抗熔焊性和高强度、高硬度等优点，目前在电工材料、电子、军工、航天等领域有着广泛的应用。

The change of conductivity and hardness of WCu composite after deformation has been investigated. The results show that the hardness is increased greatly, however, the conductivity is decreased.

本文还对钨铜材料的导电率、硬度的变化进行了研究，结果表明，二次挤压后的钨铜材料的硬度有明显提高，而导电性能反而有所下降。
