HIP技術の歴史と展望
Historical Review of HIP Technology and a Look at New Trends
小泉 光恵A  福田 保B
Mitsue KOIZUMI Tamotsu FUKUDA
This paper provides a historical review of the development and the present status of HIP technology, as well as a look at future directions. Thanks to the unique effect of the simultaneous application of isostatic pressure and temperature, a variety of value-added materials and machinery parts have been developed for commercial use over the past twenty years. As the application fields have expanded, the HIP apparatus has also been improved to reduce operational costs. Its success in this area has made Japan one of the leading countries in the world.
It is expected that the present basic research on HIP processing in various areas will lead to new developments in HIP technology in the near future.

HIPによる高密度フェライトの焼結
Sintering of High Density Ferrite by HIP
柿崎 政夫
Masao KAKIZAKI
Magnetic head requires high density ferrite. Among various methods, hot isostatic pressing or HIP is most suitable one for the densification of ferrite, especially Mn-Zn ferrite. Like many other ceramics, in most cases, presintered ferrite block is HIP'ed without capsule. Crucial issues for ferrite are heating/ cooling speed and atmosphere control. Atmosphere at HIP is controlled by ferrite powder, in which presintered ferrite block is embeded. Otherwise, Oxygen containing Argon gas is used as pressure/heat medium instead of pure Argon.

PZTおよびPLZT磁器のHIP処理
Hot Isostatic Pressing of PZT and PLZT Ceramics
高田 光裕
Mituhiro TAKATA
This paper provides an overview of the method of hot isostatic pressure treatment of lead-zir-conate-titanate (PZT) and lead-lanthanum-zirconate-titanate(PLZT) ceramics. Densified PZT ceramics are useful for miniaturized electronic components. PLZT ceramics sintered by HIP exhibit a high transmittance spectrum without serious growth of crystal grains. These microscopically uniform PLZT ceramics are a response to demands for good machinability, and will be the best candidate for optical micro-shutters for electrophotographic printers, in which switching time in micro-seconds is required.

SHS/HIPの展開
Development of SHS/HIP Processing
宮本 欽生
Yoshinari MIYAMOTO
A variety of new material processing techniques have been developed by combining Self-propagating High-temperature Synthesis (SHS) with HIP technology. SHS/HIP nitriding makes it possible to produce unique complex powers, such as Si3N4-SiC and NbN1-xCx, or nitrided Ti and Nb components. SHS/HIP sintering can be used to fabricate new composites such as functionally gradient materials. SHS/HIP casting completes the sysnthesis and simultaneously forms the NiAl intermetallic. Accompanied by chemical heats of 2000 K or more, these processes can be completed within instants.
This paper reviews recent developments in the SHS/HIP process and the resulting materials.

W/Cu傾斜組成材料の開発
Development of Tungsten/Copper Gradient Material
伊藤義康A 高橋雅志A 高野廣久B
Yoshiyasu ITOU Masashi TAKAHASHI Hirohisa TAKANO
A sintering and infiltration technique to manufacture functionally gradient materials has been developed. This technique consists of two steps and is suitable for manufacturing a tungsten (W)/copper(Cu) gradient material. The first step is to make a sintered tungsten with the gradient pore distribution. The second step is to infiltrate a molten copper into the pores. In this technique, capsule-free HIP (Hot Isostatic Pressing) treatment is effectively used for fully densifying the surface tungsten layer and for eliminating only closed pores in the other layers. Capsule HIP treatment is effective to fully infiltrate a molten copper into open pores of the sintered tungsten.
The tungsten/copper gradient material has an excellent ability to reduce thermal stress and has good thermal conductivity from the tungsten layer to the copper. It is because of continuous microstructure change from one layer to another. The results of heating tests using electron beam irradiation equipment successfully showed that the tungsten/copper gradient materials can endure a stationary heat flux of up to 15 MW/m2, which is necessary for divertor plate as a plasma facing component in the ITER (International Thermonuclear Experimental Reactor).

Application of High Pressure to the Oxide Superconductor
林征治 小川陸郎 江木俊雄
Seiji HAYASHI Rikuo OGAWA Toshio EGI
The applications of high pressure technology to oxide superconductors are reviewed. These applications can be classified into three categories: controlling the superconducting properties, investigating superconducting mechanisms, and producing new superconducting materials. Examples of each category are discussed. High pressure is considered to be useful means for the investigation of oxide semiconductors.

連続式シンターHIP装置導入によるPCBドリルの品質向上
Improvement in Quality of PCB-drills Made of Micro-grained
Cemented Carbide by Using Continuous Sinter-HIP Equipment
斎藤豪A 尾添俊二B 小堀景一C
Tsuyoshi SAITO Toshizi OZOE Keiichi KOBORI
Recently, the demand for drills for printed circuit boards(PCB-drills) has increased with the growth of the electronics industry. WC-Co alloys with relatively fine grain size have been put to industrial use, but the drills are now required to have more and more excellent wear and breaking resistance, as PCB has come to have a higher density. For that reason, micro-grained cemented carbide has become to be of great importance. In such circumstances, new micro-grained grades(MD10, MD20 and MD30) specially designed for PCB-drills have been developed, and the mass production of PCB-drill blanks having a stable high quality and reliability has been available through the use of a continuous Sinter-HIP equipment.

HIP装置の最近の動向
Recent Trends in HIP Equipment and Associated Systems
石井孝彦
Takahiko ISHII
As the applications of HIP have expanded, demands for its new abilities have also increased. And, to meet those demands, various equipment has been developed in the past twenty years. Today, the maximum temperature reaches 3000℃, the pressure ranges from 300 Pa to 980MPa, and the pressure medium gas can be nitrogen, argon, with oxygen depending on the materials treated. Moreover, various HIP systems have been developed to improve productivity or to reduce process costs, such as pre-heating-systems, or rapid cooling HIP systems, the "Sinter+HIP" system.
This paper describes these trends in HIP equipment and systems.

波動関数から見た圧力の概念
New Conception of High Pressure by Wave Functions
妹尾允史
Masafumi SENOO
This article reviews a new quantum mechanical conception of high pressure and some applications in solids, as one of recent developments in marionics. A new force operator in quantum mechanics, which is proposed by the author, is obtained from differentiating of momentum expectation of a quantum particle by time. When this quantum operator is worked to the wavefunctions, the force expectation values, which is called "marion force" after the marionics, can be obtained. The average pressure from this marion force is considered as the new concept of pressure due to the electron momenta in solids. This pressure is in good agreement with the virial pressure which is obtained thermodynamically from average energy of free electron solids. Marionics, which is also new idea of a industrial quantum mechanics or a quantum materials dynamics (QMD), is briefly introduced.

日本の衝撃超高圧力研究-1980年以前
Very High Pressure Research Utilizing Shock Wave Techniques in Japan-Before 1980
澤岡 昭
Akira SAWAOKA
The first study of shock very high pressure in Japan started at Defense Academy of Japan in the latter half of 1950. About 1970, there was a movement to establish National Very High Pressure Laboratory, which ended unsuccessful. Science and Technology Agency, however, performed research and development on shock very high pressure as a project in 1972-75 and 1977-79. The project was the start to introduce a remarkable progress in shock experiment technology in Japan.

"Inspection anew on the spot, followed by 13 years of court debates"
細見暁
Satoru HOSOMI
In the course of law suits for its possible infringement on GE's patents, another inspection was taken at Komatsu's Hiratsuka plant in March 1967 and proved this time that the apparatus in question were capable of producing diamond.
GE's cause was rejected in 1975 by the Tokyo District court; the 15 years of litigation came to an end when the High Court, after five more years of examination, rejected GE's appeal in 1980 and the latter decided not to appeal to the Supreme Court.

"My Secret Devices": How to Use the Beveled Diamond Anvils
竹村謙一
Kenichi TAKEMURA
Recent development of the diamond-anvil-cell technology has made it possible to generate ultrahigh pressures exceeding 100GPa with the use of the beveled diamond anvils. Since the sample size for such studies decreases to about 50μm, it requires special devices and techniques for the sample preparation like a microdrilling machine.
