Measurement of anisotropic stress field in a gasketed diamond-anvil cell

B. Okai; O. Shimomura; Ikuya Fujishiro

Abstract A new technique is proposed to evaluate the axial and lateral stress components, pz and pr, separately within the solid pressure medium of a gasketed diamond cell. The values of pz and pr are obtained from shifts of the R-line of two ruby plate fragments placed in a pressure chamber, one having crystal plane (11 2 0) and the other (0001) parallel to the anvil face.

Viscosity measurement of lubricants under high pressure.

Ikuya Fujishiro; Yuichi Nakamura; Satoshi Matsuhio

ダイヤモンドアンビル高圧力装置の中に Ni 球を封入し,その落下速度を光学的に測定することにより潤滑油の粘度の圧力効果を測定する装置を試作し,数種のパラフィン系炭化水素の粘度-圧力関係を最高 4 GPa まで求めた.また,圧力測定用ルビー R1 蛍光線幅の広がりから試料液体のガラス転移圧力を推定した.これは圧力-粘度関係ともほぼ一致し,これらの方法は超高圧力下における粘度挙動の把握に有効なことを示した.
