    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.
