中文摘要：
利用机械合金化法制取W/Cu合金化粉末。预压合金粉末在不同温度下通氢还原,将还原后的合金粉末在直接爆炸压制成型的装置中进行爆炸固结,爆炸固结样品相对密度最高达到了98.1%。研究了粉体的还原温度对固结体致密度的影响。分析了样品的微观结构,对样品做EPMA、断口SEM观察以及维氏硬度、电导率的测量。结果表明,W/Cu合金化粉末在爆炸冲击波作用下能够结合成高致密体,合金材料具有高硬度、组织均匀的特点,物理性能良好。
英文摘要：
The W/Cu alloy powders were produced by mechanical alloying.The pre-compacted powder mixtures were reduced at various temperatures in the flowing hydrogen atmosphere.The reduced powders were explosive consolidated to fabricate dense W/Cu alloy in a cylindrical configuration/single tube set-up.The biggest density of the compact samples arrived at 98.1% T.D.The microstructure of the samples was analyzed.The sample was analyzed by EPMA and the fracture surface was investigated by SEM.The hardness and conductivity were measured.The results showed that W/Cu alloy powders could been consolidated in high density and the alloy material had high hardness and uniform structure.The physical performances is fine.
