| 1 | Constructing two-scale network microstructure with nano-Ti5Si3 for superhigh creep resistance显示文摘The improvement of mechanical properties must be achieved by designing and constructing more suitable microstructure,such as hierarchical microstructure.In order to significantly enhance the creep resistance of titanium matrix composites(TMCs),two-scale network microstructure was constructed including the first-scale network(<150μm)with micro-TiB whisker(TiBw)reinforcement and the second-scale network(<30μm)with nano-Ti5Si3 reinforcement by powder metallurgy and in-situ synthesis.The results showed that the creep rate of the composite was remarkably reduced by an order of magnitude compared with the Ti6Al4V alloy at 550℃,600℃,650℃ under the stresses between 100 MPa and 350 MPa.Moreover,the rupture time of the composite was increased by 20 times,compared with that of the Ti6Al4 Valloy at 550℃/300 MPa.The superior creep resistance could be attributed to the hierarchical microstructure.The micro-TiBw reinforcement in the first-scale network boundary contributed to creep resistance primarily by blocking grain boundary sliding,while the nano-Ti5Si3 particle in the second-scale network boundary mainly by hindering phase boundary sliding.In addition,the nano-Ti5Si3 particle was dissolved,and precipitated with smaller size than the primary Ti5Si3.This phenomenon was attributed to Si element diffusion under high temperature and external stress,which could further continuously enhance the creep resistance.Finally,the creep rate during steady-state stage was significantly decreased,which manifested superior creep resistance of the composite. | Y.Jiao L.J.Huang S.L.Wei H.X.Peng Q.An S.Jiang L.Geng | 2019 | Journal of Materials Science & Technology2019，35，8： | 14 |

| 7 | Accelerated protons with energies up to 70 MeV based on the optimized SG-Ⅱ Peta-watt laser facility显示文摘The target backsheath field acceleration mechanism is one of the main mechanisms of laser-driven proton acceleration(LDPA)and strongly depends on the comprehensive performance of the ultrashort ultra-intense lasers used as the driving sources.The successful use of the SG-II Peta-watt(SG-II PW)laser facility for LDPA and its applications in radiographic diagnoses have been manifested by the good performance of the SG-II PW facility.Recently,the SG-II PW laser facility has undergone extensive maintenance and a comprehensive technical upgrade in terms of the seed source,laser contrast and terminal focus.LDPA experiments were performed using the maintained SG-II PW laser beam,and the highest cutoff energy of the proton beam was obviously increased.Accordingly,a double-film target structure was used,and the maximum cutoff energy of the proton beam was up to 70 MeV.These results demonstrate that the comprehensive performance of the SG-II PW laser facility was improved significantly. | H.H.An W.Wang J.Xiong C.Wang X.Pan X.P.Ouyang S.Jiang Z.Y.Xie P.P.Wang Y.L.Yao N.Hua Y.Wang Z.C.Jiang Q.Xiao F.C.Ding Y.T.Wan X.Liu R.R.Wang Z.H.Fang P.Q.Yang Y.E.Jiang P.Z.Zhang B.Q.Zhu J.R.Sun B.Qiao A.L.Lei J.Q.Zhu | 2023 | High Power Laser Science and Engineering2023，11，5： | 0 |
| 8 | Dynamically pre-compressed hydrocarbons studied by self-impedance mismatch显示文摘Using the SG-III prototype laser at China Academy of Engineering Physics,Mianyang,we irradiated polystyrene(CH)samples with a thermal radiation drive,reaching conditions on the principal Hugoniot up to P≈1 TPa(10 Mbar),and away from the Hugoniot up to P≈300 GPa(3 Mbar).The response of each sample was measured with a velocity interferometry diagnostic to determine the material and shock velocity,and hence the conditions reached,and the reflectivity of the sample,from which changes in the conductivity can be inferred.By applying the selfimpedance mismatch technique with the measured velocities,the pressure and density of thermodynamic points away from the principal Hugoniot were determined.Our results show an unexpectedly large reflectivity at the highest shock pressures,while the off-Hugoniot points agree with previous work suggesting that shock-compressed CH conductivity is primarily temperature-dependent. | N.J.Hartley C.Zhang X.Duan L.G.Huang S.Jiang Y.Li L.Yang A.Pelka Z.Wang J.Yang D.Kraus | 2020 | Matter and Radiation at Extremes2020，5，2： | 0 |
