| 1 | OXIDATION OF A TWO-PHASE Cu-75Cr ALLOY IN AIRAT 700-900℃显示文摘The cormsion in air of a two-phase Cu-75Cr alloy was studied at 700-900℃. Thealloy cormded nearly parabolically at 700-800℃, but at 900℃ its instantaneousparabolic mte constant decreased with time. The scales were complex and consistedof an outermost layer of copper oxide generally followed bg a layer of the double ox-ide Cu2 Cr2 O4 sometimes containing particles of unoxidized chromium surmunded bya chromia layer. An innermost layer of chromia was also observed in some cases.Finally metallic copper was al8o frequently mixed with chromia particles. No Cr de-pletion was observed in the alloy close to the inteffoce with the scale. In any case,this alloy was not able to form an exclusive continuous protective chromia layer. Thespecial cormsion behavior Of this alloy is typical of two-phase binary systems with alange solubility gaP in which the outwaof dthesion fiux of the most-reactive componentin the alloy is strongly reduced and may be inswncient to fOrm a protective externallayer of the cormsponding oxide. In paTticular, the presence of particles of Cr withina double oxide layer is very unusual and is allowed only for the kinetic reason. | F. Gesmundo Y Niu F. Vianiand D.L.

| 2 | SCC MECHANISM OF STAINLESS STEEL AISI 321 IN ACIDIC CHLORIDE SOLUTION显示文摘It is verified that stainless steel AISI 321 is in the active anodic dissolution state in 0.5mol/L HCll+0.5 mol/L NaCl solution at 55℃.The SCC of the steel in the solution cannot be reasonably explained by passive film rupture-nepasivation theory and by hydrogenembrittlement theory.There are evidences that the fracture stress at the tip of the cracksis reduced by anodic dissolution due to its role in relieving strain hardening layer at cracktip. | HUANG Yanliang CAO Chu’nan LIN Haichao LU Ming Corrosion Science Laboratory,Institute of Corrosion and Protection of Metals,Academia Sinica,Shenyang,China Ph D student,Institute of Corrosion and Protection of Metals,Academia Sinica,Shenyang 110015,China | 1993 | Acta Metallurgica Sinica(English Letters)1993，6，12： | 3 |

| 10 | MITI PROGRAM ON HIGH TEMPERATURE INTERMETALLICS显示文摘An eight year national program aiming at the development of high temperature intermetallics was started by the Agency of Industrial Science and Technology of the Ministry of International Trade and Industry (AIST MITI) in 1989 and almost successfully ended in 1997. This national program with emphasis on basic aspects of the properties and processing of high temperature intermetallics, Ti Al and Nb Al, have given a considerable impetus to intermetallics research in Japan. This is an overview of the results of the program and implications of the program for the future development of high temperature intermetallics compounds for structural applications. Alloy design, evaluation of fundamental mechanical properties, fabrication processing and surface modification have been investigated using these two alloy systems. Based on the obtained results, the concept of alloy design was established, and new technologies, were developed for metal injection moding, casting, rheocasting, sheet casting and rolling, superplastic forming, heat treatment, melting and investment casting, gas atomization, direct rolling of alloyed powders, near net shaping by HIPing alloyed powders and oxidation resistant surface coating. Some of suggested intermetallics alloys are expected to be basics for ultra high temperature structural materials in the next generation because of the extremely high strengths at high temperature, 1 100 ℃ and 1 800 ℃, beyond conventional Ni base superalloys. | Makoto Tomita and Yusei Noguchi R&D Institute of Metals and Composites for Future Industries (RIMCOF), 25 2, Toranomon 3 Chome, Minato Ku, 105 0001, Japan | 1999 | 中国有色金属学会会刊:英文版1999，9，S1： | 1 |
