【Abstract】 In this paper,we investigated the mechanical properties of four kinds of depleted uranium DU alloys under dynamic compression at various strain-rates and ambient temperatures, using the apparatus of SHPB. We obtained the relations that the mechanical behaviour of these materials varied with the strain-rate and temperature. Experimental results show that the dynamic strength of the DU alloy made in china is similar to tungsten alloy and this DU alloy could be used as the best substitutes for tungsten’ alloys.更多还原
