Dynamic behaviors of Zr51Ti5Ni10Cu25Al9 bulk metallic glass were investigated using electric gun and magnetically driven isentropic compression device which provide shock and ramp wave loading respectively. Double-wave structure was observed under shock compression while three-wave structure was observed under ramp compression in 0 ∼ 18GPa. The HEL of Zr51Ti5Ni10Cu25Al9 is 8.97 ± 0.61GPa and IEL is 8.8 ± 0.3GPa, respectively. Strength of Zr51Ti5Ni10Cu25Al9 estimated from HEL is 5.0 ± 0.3GPa while the strength estimated from IEL is 3.6 ± 0.1GPa. Shock wave velocity versus particle velocity curve of Zr51Ti5Ni10Cu25Al9 under shock compression appears to be bilinear and a kink appears at about 18GPa. The Lagrangian sound speed versus particle velocity curve of Zr51Ti5Ni10Cu25Al9 under ramp wave compression exhibits two discontinuances and are divided to three regions: elastic, plastic-I and plastic-II. The first jump-down occurs at elastic-plastic transition and the second appears at about 17GPa. In elastic and plastic-I regions, Lagrangian sound speed increases linearly with particle velocity, respectively. Characteristic response of sound speed in plastic-I region disagree with shock result in the same pressure region(7GPa ∼ 18GPa), but is consistent with shock result at higher pressure(18-110GPa).

“…EFIs are composed of an exploding foil, a flyer plate, an accelerating chamber, and an explosive [3]. Under the action of high pressure and heavy current, exploding foil generates high-temperature and high-pressure plasma to drive highspeed flyer plates to detonate explosives [4][5][6]. EFIs can be used in engineering blasting, aerospace, and military fields.…”

Multilayer film is widely used in mechanical, optical, electronic, computer, sensor, recording, aerospace and weapon applications. In the thin‐film energy conversion device, it is desirable to use film to convert more energy. This work investigated the electric explosion performance of Ni/Cu multilayer films that were prepared by using the electrodeposition method. The cross‐section SEM image verified the layered structure of Ni/Cu multilayer foil. The metal in the Ni/Cu multilayer film grew in polycrystalline. The temperature of exothermic reaction in the Ni/Cu multilayer started at 1056 °C. We measured the current and voltage curves of foils with different bridge area. The combination of Cu and Ni in multilayer could improve the initial resistance of foil. The deposited energy of Ni/Cu multilayer foil with a bridge area of 0.4×0.4 mm was 105.57 mJ while the bridge area of 0.3×0.3 mm was 93.05 mJ at charging voltage of 3000 V. Compared with Cu foil, Ni/Cu multilayer foil with bridge area of 0.4×0.4 mm burst earlier and deposited 10.5 mJ more energy. As a result, when the modulation cycle of Ni/Cu multilayer film is 200/300 nm, the Ni/Cu multilayer foil with a bridge area of 0.4×0.4 mm has potential application in exploding foil.

“…When high current pulse is passing through metallic foil or wire in short time, the state of foil or wire changes from solid to vapor rapidly, resulting plasma with high temperature and pressure by ionized vapor. The plasma created by metallic foil or wire has many applications in electrical guns (EGs) [1][2][3][4], exploding foil initiator (EFIs) [5][6][7][8][9], exploding wire initiator. The high pressure generated by plasma can accelerate plastic flyers to km/s, which can initiate explosion or investigate impacting performance of materials.…”

The mechanisms of metal phase transition process during electrical explosion are experimentally and theoretically investigated. Past experiments of investigation are single metal foil, such as gold, aluminum, and copper. The characteristics of aluminum‐nickel (Al/Ni) multilayer foil were investigated, which means electrical behavior and energy output. The foil was fabricated by magnetron sputtering based on ceramic substrate, and lithographically patterned into bow‐tie bridge regions. Scanning electron microscopy characterization revealed the layer structure of the Al/Ni multilayer. X‐ray diffraction characterization was employed to ascertain the composition of Al/Ni. The probing of voltage‐current waveforms reveals that Al/Ni multilayer foils exhibit high voltage, short burst time and high absorbing energy in electrically heated in comparison with copper or nickel alone. We also measured the energy output of foils through velocity measurements of encapsulation layers ejected from bridge region by Photonic Doppler velocimetry. We observed flyer velocities from Al/Ni multilayer foil in the 1.6–2.9 km/s range, which is much higher than copper foil. Combined with the 1‐D non‐stationary acceleration model calculation, it is found that the chemical energy and increased electrical absorbing energy contributed to additional kinetic energy in the 40–80 mJ range.
