Abstract Scope |
Soldiers often carry large amounts of weight in ammunition; therefore, finding ways to reduce the weight could be lifesaving on the battlefield. The aim of this study is to develop a material that is stronger, lighter and cheaper than cartridge brass. The mechanical behaviour of five selected quinary copper alloys (multiphase/ high entropy alloy) and cartridge brass were investigated. Testing included quasi static, dynamic and impact tests using a universal testing machine, Split Hopkinson Pressure Bar (also known as Kolsky bar) and a single stage light gas gun (Taylor test), respectively. Microstructural examination (optical microscopy) and Vickers hardness testing is used in conjunction to further characterise the specimens. This study may prompt increased utilisation of quinary/high entropy alloys, which in turn, could lead to further revolutionary discoveries in the development of new materials. |
