The appearance of high-entropy alloys (HEAs) makes it possible for a material to possess both high strength and ductility. It is with great potential apply HEAs under extreme conditions such as in the penetration process. In this paper, experiments WFeNiMo HEA tungsten heavy alloy (WHA) projectiles penetrating medium-carbon steel were conducted by using ballistic gun two-stage light-gas that can accelerate impact velocities ranging from 1162 m/s 2130 m/s. Depth (DOP) at elevated WHA obtained...
The high pressure behavior of titanium nitride (TiN) was investigated using synchrotron radial x-ray diffraction (RXRD) under nonhydrostatic compression up to 45.4 GPa in a diamond-anvil cell. We obtained the hydrostatic equation state TiN. Fitting third-order Birch–Murnaghan state, bulk modulus derived from data varies 232 353 GPa, depending on angle ψ, orientation planes with respect loading axis. RXRD at ψ=54.7° yield K0=282±9 derivative K0′ fixed 4. have analyzed deformation mechanisms...
Reactive Materials (RMs), a new material with structural and energy release characteristics under shock-induced chemical reactions, are promising in extensive applications national defense military fields. They can increase the lethality of warheads due to their dual functionality. This paper focuses on RM casings prepared by alloy melting casting process explosive loading. Explosion experiments conventional 2A12 aluminum were conducted free field capture fireballs, temperature distribution,...
利用自行设计与集成的二级6—8型大腔体静高压装置,研究了影响八面体压腔高压发生效率的主要因素及机理,并提出了一种八面体压腔密封的简化力学模型.针对于10/4(八面体传压介质边长为10 mm,二级WC立方体增压块截角边长为4 mm)组装的实验结果发现:预密封边尺寸会显著影响八面体压腔的压力产生效率;在腔体压力为12 GPa左右时,高压发生效率随八面体MgO传压介质初始密度的增加而提高;在15 GPa以上时,影响压力产生效率的主要因素是WC增压立方块本身的强度以及加压过程中所形成密封边的尺寸及材料.
In order to investigate the deformation behavior and penetration performance of WFeNiMo high-entropy alloy under different strain rates, static mechanical properties was tested by universal material testing machine dynamic SHPB (split Hopkinson pressure bar). The micro mechanism characteristics rates also discussed. Based on ballistic gun test platform, fragments typical tungsten (93W-4.9Ni-2.1Fe, wt%) finite thickness steel target studied. relationship between process two kinds damage...
As a kind of multi-principal component alloy, high-entropy alloy breaks through the design idea traditional single-principal alloys, and shows excellent properties different from alloy. It has good application prospect in extreme environments including high temperature, pressure strain rate. Analyzing impact deformation characteristics entropy micro, meso macro scale is great importance for its engineering application, which includes influences element effect, macrostructure temperature rate...
In this paper, the mechanical properties, penetration characteristics, and deformation behaviors of FeNiCoCr high-entropy alloys (HEAs) annealed at different temperatures were investigated. The quasi-static dynamic compression tests conducted by a universal testing machine Split Hopkinson Pressure Bar (SHPB) system, respectively. Furthermore, experiments long rod projectiles (LRPs) HEAs into semi-infinite steel targets launched small caliber ballistic gun with velocities ranging from 650 m/s...
Al/Ni multi-layered composites were manufactured by cold rolling with different passes. The influence of passes on the mechanical properties and shock-induced chemical reaction (SICR) behaviors was investigated quasi-static compression tests impact initiation experiments. A scanning electron microscopy (SEM) used to obtain microstructures composites, from images explain experimental results. results show that cold-rolled behave more plastically than powder-compacted do. strength increases...
