| 3 | Dynamic mechanical relaxation behavior of Zr_(35)Hf_(17.5)Ti_(5.5)Al_(12.5)Co_(7.5)Ni_(12)Cu_(10)high entropy bulk metallic glass显示文摘Non-equiatomic high entropy bulk metallic glasses were reported recently and show unique mechanical and physical properties.Dynamic mechanical relaxation behavior of Zr_(35)Hf_(17.5)Ti_(5.5)Al_(12.5)Co_(7.5)Ni_(12)Cu_(10)high entropy bulk metallic glass was investigated by dynamic mechanical analysis(DMA)and the mechanical spectra could be well described by the quasi-point defects(QPD)theory.Compared to typical metallic glasses,the intensity of theβrelaxation of Zr_(35)Hf_(17.5)Ti_(5.5)Al_(12.5)Co_(7.5)Ni_(12)Cu_(10)high entropy bulk metallic glass is lower due to the sluggish diffusion.At the same time,the correlation factor is higher than that of conventional metallic glasses and this is ascribed to the high configuration entropy.In parallel,physical aging below the glass transition temperature leads to a decrease of atomic mobility,caused by a decrease of the concentration of defects. | L.T.Zhang Y.J.Duan T.Wada H.Kato J.M.Pelletier D.Crespo E.Pineda J.C.Qiao | 2021 | Journal of Materials Science & Technology2021,,24: | 2 |

| 5 | Inhomogeneous dealloying kinetics along grain boundaries during liquid metal dealloying显示文摘In this study, the inhomogeneous dealloying phenomenon during the liquid metal dealloying(LMD) was investigated using FeNi+Mg and(FeCo)Ni+Mg systems. For the FeNi+Mg system, the inhomogeneous dealloying and wetting of Mg melt occurred along triple junction(TJ) and grain boundary(GB).Temperature increase enhances the inhomogeneous dealloying kinetics and leads to the formation of the plate-shaped abnormal ligaments at the GB region. The energy banlance between a GB energy(γGB)and solid-liquid interface energies(γsl) is the key factor governing the inhomogeneous dealloying and wetting. Particularly, the low-energy twin boundaries were unaffected by the inhomogeneous dealloying.Therefore, precursor microstructure is an important factor determining the final morphology of dealloyed material as well as its physical properties. In the case of the(FeCo)Niprecursor, all TJ and GB were stable against the preferred penetration of Mg melt from 600 ℃ to 800 ℃. It was concluded that a minor addition of alloying elements(VorCr) changes GB characteristics as well as γslof the precursor alloy.Consequently, this significantly influences dealloying mechanisms and final morphology of the dealloyed material. The current findings demonstrate the importance of GB engineering in the precursor materials for the technological application of liquid metal dealloying for the synthesis of advanced structural and functional materials. | S.-H.Joo Y.B.Jeong T.Wada I.V.Okulov H.Kato | 2022 | Journal of Materials Science & Technology2022,,11: | 1 |

| 7 | Analysis of the anelastic deformation of high-entropy Pd_(20)Pt_(20)Cu_(20)Ni_(20)P_(20) metallic glass under stress relaxation and recovery显示文摘The anelastic deformation behavior of Pd_(20)Pt_(20)Cu_(20)Ni_(20)P_(20) high-entropy metallic glass was probed by monitoring the stress relaxation and recovery processes. The stress relaxation under consecutive strain steps can be described by the Kohlrausch-Williams-Watts(KWW) function. In addition, considering a hierarchy of relaxation processes related to the structural heterogeneity, a constitutive model is proposed in order to describe the whole process of stress relaxation and determine the contribution of different time scales. Moreover, a crossover from stochastic activation to percolation of flow defects with the ultimate strain can be observed during stress relaxation process. The anelastic recovery process after a strain step is studied as a function of the initial strain level and characterized by means of a direct spectrum analysis. The peaks in the recovery time-spectra revealed the evolution of flow defects in Pd_(20)Pt_(20)Cu_(20)Ni_(20)P_(20) high-entropy metallic glass. The understanding of the atomic free-volume zones effect and the anelastic deformation provides important insight into how atomic structural features affect the deformation behavior of high-entropy metallic glasses, and may provide a new avenue into the improvement of their mechanical properties. | Y.J.Duan L.T.Zhang T.Wada H.Kato E.Pineda D.Crespo J.M.Pelletier J.C.Qiao | 2022 | Journal of Materials Science & Technology2022,,12: | 0 |

| 9 | Benchmark Integral Cross Sections for Electron Impact Excitation of the n=2 States in Helium显示文摘<正> In this paper, we present integral cross sections (ICS) for electron impact excitationof the n= 2 levels in helium in the impact energy range of 23.5 eV to 35 eV. The ICS of each finalstate, 2~3S, 2~1S, 2~3p and 2~1P, has been determined by integration of the angular differential crosssections (DCS) over all of 0° to 180°, where those DCS were obtained from both our previousexperiments and the extrapolation using the convergent close coupling calculation. The presentexperimental ICS for the optically allowed 2~1p transition state are also compared with thoseobtained from the BEf-scaling method. Very good agreement between the experimental andBEf-scaled 2~1P ICSs is generally found in the measured impact energy region. | M.HOSHINO H.KATO D.SUZUKI H.TANAKA I.BRAY D.V.FURSA S.J.BUCKMAN O.INGLFSSON M.J.BRUNGER | 2010 | Plasma Science and Technology2010,12,3: | 0 |
| 10 | π~0 Photoproduction on Deuteron for Photon Energies from 0.6 to 1.15 GeV显示文摘Differential and total cross sections of the γp→π0p and the γd→π0pn reaction were measured for photon energies between 640 and 1 150 MeV. The data have been compared with SAID and MAID model calculations. π0 photoproduction on the deuteron shows a strong suppression of the 2nd resonance which is clearly seen in the γp→π0p reaction. | F.Miyahara H.Fukasawa R.Hashimoto T.Ishikawa M.Itoh T.Iwata H.Kanda J.Kasagi H.Kato T.Kinoshita K.Maeda M.Matsuzawa T.Michigami K.Motiduki K.Murakami T.Nakabayashi K.Nawa T.Nomura K.Okamura H.Okamura H.Okuyama Y.Onodera Y.Saito T.Sasaki H.Shimizu T.Shishido S.Suzuki K.Suzuki Y.Tajima S.Takita T.Takahashi H.Ueno S.Yamaguchi H.Yamazaki H.Y.Yoshida | 2009 | 原子核物理评论2009,26,S1: | 0 |
