中文摘要:
      本文运用爆炸压实去固结钨锡合金粉末。为了的到钨锡合金粉末,先研究了钨与锡之间的可焊接性,检测结果表明钨锡的交界面结合紧密,说明在这种方法下钨锡是可以焊接在一起的。钨锡的可焊性为钨锡合金粉末的制备提供了依据。材料的维氏硬度对其粉末的爆炸压实至关重要,为了得到钨锡材料的维氏硬度,运用爆炸压实去固结钨锡合金粉末。运用连续压倒探针测量实验中所使用的铵油炸药的爆速,并运用测量的出爆速计算出炸药的爆压约为3.24GPa. 爆炸压实后钨锡块体的密度为16.017 g cm-3。实验得到的钨锡块体的维氏硬度在210-247HV之间。

英文摘要:
      This paper aimed to use explosive consolidation to fabricate tungsten–tin alloy powder. The tungsten–tin alloy powder was prepared at first. In order to obtain tungsten–tin alloy powder, the weldability between tungsten and tin was studied. The tungsten–tin interface did not show any crack, indicating the successful welding of tungsten and tin. Result provided basis for producing tungsten–tin alloy powder. The Vickers hardness (HV) is very important to explosive consolidation. In order to obtain HV of the tungsten–tin alloy material, the tungsten–tin powder was consolidated by explosive consolidation. The detonation velocity (DC-J) of ammonium nitrate fuel oil (ANFO) was measured by continuous velocity probe. The detonation pressure (PC-J) was approximately 3.24 GPa simulated by DC-J. The density of the consolidated tungsten–tin alloy block was 16.017 g cm-3. The hardness values of the tungsten–tin alloy block were in the range of 210–247 HV.
