| 爆発圧着 Explosion Bonding |
| 伊妻 猛志 Takeshi IZUMA |
| Explosion bonding process introduced commercially
in 1960 has developed steadily and expanded
its applications. This unique joining process
makes use of controlled explosive energy
and enables us to bond various kinds of dissimilar
metal combinations metallurgically. This
paper reviews the development of the process
and describes bonding conditions, advantages
and limitations of the process, and its applications. [Explosion bonding, Clad, Transion joint] |

| ダイヤモンドの衝撃合成 Shock Synthesis of Diamond |
| 関根 利守 Toshimori SEKINE |
| Shock synthesis of diamond are reviewed.
Recovery experiments as well as in
situ observations
on the conversion to diamond from various
carbon sources are summarized. The
transition
is explained by both diffusional and
diffusionless
mechanisms depending upon shock conditions
and starting materials. [diamond, shock synthesis, explosive synthesis, carbons] |

| Gruneisen型状態方程式と衝撃波 Gruneisen Equation of State and Shock Waves |
| 永山 邦仁 Kunihito NAGAYAMA |
| Based on the Gruneisen assumption, thermodynamic
analysis of the Gruneisen equation of state
leads us to the introduction of two new thermal
variables, the product of which forms the
thermal internal energy. One of them, Θ(v)defines
a characteristic temperature of solids as
a function of volume, while the other, C(S)
is a state variable as a function of entropy,
and conjugate to Θ(v). The specific heat
is shown to be a function of entropy. These
results are also derived by the statistical
mechanics of harmonic oscillator systems,
but not using the Debye model. [Gruneisen parameter, Equation of State, High Pressure, Thermal Variable, Statistical Mechanics] |

| セラミックスの衝撃圧縮挙動の計測 Measurements of Shock Compression Behaviors on Ceramic Materials |
| 真下 茂 Tsutomu MASHIMO |
| In shock-compression measurement on solids,
it is important to use controlled, high-quality
specimens and to use high-capability measurement
apparatuses. We have been investigating the
shock-yielding property, high-pressure phase
transition, equation of state, etc. of ceramics,
minerals, semiconductors, etc., through shock-wave
measurements. In this report, at first, the
improved measurement methods combined with
the keyed-powder gun used in our studies
are described. In the next, the recent studies
on selected good quality ceramics(Zro2, Si3N4, AIN, B4C) are reviewed. The typical effects of shock
compression on yielding property and phase
transition of ceramics are shown, and the
yielding mechanism and the correlation with
material characterizations are discussed.

| 衝撃焼結プロセスの設計と応用 Design of Shock Compaction Process and Some Applications to New Materials |
| 近藤 建一 Ken-ichi KONDO |
| Shock compaction methods have various unique
features for fabricating new materials, especially
consisting of both metastable phase and microstructure.
Some phenomenological theories for powder
systems under shock loading are reviewed
in order to design the shock compaction process,
and some examples of the new materials developments
are introduced for discussing issues of the
process and the applications. [shock compaction, shock compression, shock chemistry, nanocrystalline materials, powder system, magnetic materials] |

| 豪州褐炭液化(BCL)プロセス高温高圧水添反応による輸送用液体燃料の合成 Brown Coal Liquefaction (BCL) Process: Synthesis of Liquid Fuel for Transportation by Hydrogenation of Brown Coal |
| 大隈 修 Osamu OOKUMA |
| Victorian brown coal in Australia has huge
reserve(202 GT)and is only used for power
generation near its mines. This is because
it contains more than 60 wt% moisture and
ignites spontaneously after drying. Nippon
Brown Coal Liquefaction Co. (NBCL) has developed
the BCL(Brown Coal Liquefaction) process
which converts the brown coal into high value
liquid fuel for transportation such as gasoline
under high temperature and high pressure
conditions. This process is a two-stage direct
liquefaction process and consists of four
unit sections: dewatering, primary hydrogenation,
solvent de-ashing, and secondary hydrogenation.
This paper reviews the direct coal liquefaction
technology, and the detail of the BCL process
which has been confirmed by operation of
the 50 T(dry coal)/D pilot plant constructed
in Australia. [brown coal, coal liquefaction, BCL process, coal oil, dewatering, hydrogenation, de-ashing] |

| フッ化メタンの超高圧物性 High-Pressure Properties of Fluorinated Methanes |
| 呉 有紅 清水 宏晏 Wu Youhong, Hiroyasu SHIMIZU |
| It is known that fluorinated methanes CH3F (HFC-41), CH2F2(HFC-32), CHF3 (HEC-23), CF4 (FC-14) and CHF2Cl (HCFC-22) have considerably more importance
to mankind, which have been suggested as
the potential replacements for chlorofluorocarbons
(CFCs). This article reviews recent high-pressure
Raman studies of CH3F, CH2F2, CHF3, CF4 and CHF2Cl, and high-pressure FT-IR study of CH2F2. The pressure-induced phase transitions,
the pressure dependence of molecular vibrations,
the mode-Gruneisen parameters and the other
characteristic behavior of these condensed
molecules have been presented and discussed. [fluorinated methanes, Raman scattering, FT-IR, phase transition, molecular crystal, mode-Gruneisen parameter, Fermi resonance, LO-TO splitting, transition dipole-transition dipole interaction, covalent-bond, ionic-bond] |
