    摘要:

    本文運用爆炸壓實去固結(jié)鎢錫合金粉末。為了的到鎢錫合金粉末,先研究了鎢與錫之間的可焊接性,檢測結(jié)果表明鎢錫的交界面結(jié)合緊密,說明在這種方法下鎢錫是可以焊接在一起的。鎢錫的可焊性為鎢錫合金粉末的制備提供了依據(jù)。材料的維氏硬度對其粉末的爆炸壓實至關(guān)重要,為了得到鎢錫材料的維氏硬度,運用爆炸壓實去固結(jié)鎢錫合金粉末。運用連續(xù)壓倒探針測量實驗中所使用的銨油炸藥的爆速,并運用測量的出爆速計算出炸藥的爆壓約為3.24GPa. 爆炸壓實后鎢錫塊體的密度為16.017 g cm-3。實驗得到的鎢錫塊體的維氏硬度在210-247HV之間。

    Abstract:

    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.
