摘　　要：对不同Cu含量[20%～50%(质量分数)]的热挤压后的W-Cu合金坯料进行轧制,通过对比得出最佳轧制工艺参数,并制备出微观组织均匀、致密度高、性能优异的W-Cu合金板材。结果表明:轧制力随着道次轧下量的增加而逐渐增大,并且当一次轧下量超过60%时,轧制力急剧增加;随着轧制变形量的增加,Cu相发生变形,W相形状基本不发生变化,但W相有细化的趋势;轧制变形能在保持W-Cu合金热挤压后高组织均匀性、高致密度、高性能的基础上获得薄板甚至是箔材。The tungsten copper alloy blanks of different content of copper （20wt. % Cu-50wt. % Cu） were obtained by hot extrusion and their sheets with uniform microstructnre, high density and excellent property were prepared by rolling. The experimental results show that the rolling force increase with the increase of rolling reduction, and when the rolling reduction exceeds 60% the roiling force increase sharply. The cooper phase deforms and the tungsten phase doesn＇ t deform basically with the increase of rolling deformation. All results show that high performance tungsten copper alloy can be obtained by hot rolling technology.
