| 2 | High Strain Rate Deformation Behavior of Zirconium at Elevated Temperatures显示文摘High temperature mechanical behaviors of zirconium at high strain rate of 103 s-1 were studied by split Hopkinson pressure bar (SHPB).The influences of strain rate and temperature on the micro-structural evolution,as well as the occurrence of shear localization and subsequent fracture,were also investigated.It s found that the compressive stress-strain response depends sensitively on the applied strain rate and test temperature.Micro-structural observations revealed that the density of the twinning grains reduced as the temperature increased,and increased in response to increasing strain rate.Optical observation of the fracture surfaces showed evidence of adiabatic shear localization along the fracture planes prior to crack formation.Finally,a special form of the Zerilli-Armstrong model was used to describe the mechanical response of zirconium. | Dawu Xiao Yinglei Li Shisheng Hu Lingcang Cai | 2010 | Journal of Materials Science & Technology2010，26，10： | 1 |

| 5 | Pressure Effect on Elastic and Lattice Dynamic Properties of Beryllium Selenide from First Principles显示文摘The lattice dynamic, elastic, and thermodynamic properties of Be Se were investigated with first principles calculations. The phase transition pressure from the zinc blende(B3) to the nickel arsenide(B8) structure of Be Se was determined. The elastic stability analysis suggests that the B3 structure Be Se is mechanically stable in the applied pressure range of 0-50 GPa. Our lattice dynamic calculations show that the B3 structure is lattice dynamically stable under high pressure. Within the quasiharmonic approximation, the thermodynamic properties including the constant volume heat capacity and constant pressure heat capacity are predicted. | 罗雰 GUO Zhicheng CAI Lingcang | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，2： | 0 |
| 6 | Equation of state of fluid helium at high temperatures and densities显示文摘Hugoniot curves and shock temperatures of gas helium with initial temperature 293 K and three initial pressures 0.6, 1.2, and 5.0 MPa were measured up to 15000 K using a two-stage light-gas gun and transient radiation pyrometer. It was found that the calculated Hugoniot EOS of gas helium at the same initial pressure using Saha equation with Debye-Hückel correction was in good agreement with the experimental data. The curve of the calculated shock wave velocity with the particle velocity of gas helium which is shocked from the initial pressure 5 MPa and temperature 293 K, i.e., the D^u relation, D = C0+λu (u < 10 km/s, λ = 1.32) in a low pressure region, is approximately parallel with the fitted D^u (λ = 1.36) of liquid helium from the experimental data of Nellis et al. Our calculations show that the Hugoniot parameter λ is independent of the initial density ρ0. The D^u curves of gas helium will transfer to another one and approach a limiting value of compression when their temperature elevates to about 18000 K and the ionization degree of the shocked gas helium reaches 10-3. | CAI Lingcang CHEN Qifeng GU Yunjun ZHANG Ying ZHOU Xianming JING Fuqian | 2005 | Science China(Physics,Mechanics & Astronomy)2005，48，6： | 0 |
