钨锡复合粉末的制备与爆炸压实（英文）
|
摘要
研究了钨锡合金粉末的制备及其爆炸压实。首先,研究了钨与锡之间的可焊接性,从而为制备钨锡合金粉末提供了依据。然后,通过在强碱溶解中加热钨粉和锡粉制备出了钨锡合金粉末。最后,对钨锡合金粉末进行爆炸压实,并使用连续压导探针测量实验中所使用炸药的爆速。结果表明:使用测得的爆速计算出炸药的爆压约为3.24 GPa。对爆炸压实后得到的钨锡块体进行表征,测得其密度为16.017 g·cm~(-1),维氏硬度在2100～2470 MPa之间。
The preparation tungsten-tin alloy powder and its explosive consolidation were studied. In order to obtain tungsten-tin alloy powder, weldability between tungsten and tin was studied at first. Then, tungsten-tin alloy powder was prepared by heating tungsten powder and tin powder in strong alkali solution. Finally, the explosive consolidation of tungsten-tin alloy powder was carried out, and the detonation velocity of the explosive used in the experiment was measured with a continuous velocity probe. The results show that the detonation pressure of the explosive is about 3.24 GPa calculated by the measured detonation velocity. The density of the consolidated tungsten-tin alloy block is 16.017 g.cm~(-3). The hardness(HV) values of the tungsten-tin alloy block are in the range of 2100～2470 MPa.
