| Research Abstract |
Intermetallic compounds, in particular aluminides and silicides with high metlting points, have immense potential as new high-temperature structural materials since they often possess not only attractive high-temperature mechanical properties but also excellent oxidation resistance. In recent years there has been an enormous increase in the research and development activity on such intermetallic compounds for high temperature structural applications since the requirements for the strength and stiffness and the oxidation and corrosion resistance at high temperatures are becoming increasingly severe in the field of high temperature technologies such as those for gas turbines.
The research program of the Ministry of Education, Scence, Sports and Culture (MESSC) "Intermetallic Compounds as New High Temperature Structural Material" was started in 1992 as one of scienctific researches on priority areas and was finished in 1994. In the program, the following fundamental topics on high-temperat

ure intermetallic compounds, in particular aluminides and silicides, were studied : (i) crystal structure and phase stability, (ii) deformation and fracture mechanisms, (iii) design and control of microstructure, (iv) environmental embrittlement and other environmental effects. A total of 67 research teams from more than 15 universities were involved in the program. Of the research teams, 31 teams participated in the program for the whole three years, 13 teams for two years and 23 terams for only one year. The total budget for the program was about 700 million yen which was mostly for research equipment and materials.
The steering committee of the program organized an international symposium "Intermetallic Comopunds for High-Temperature Structural Applications" in conjunction with the Third Japan International SAMPE Symposium held in Makuhari, Chiba on December 7 - 9,1993. The research teams have published numbers of papers in the proceedings and various other conference proceedings and journals. The steering committee is obliged to summarize the results of the studies carreid out by all the research teams having participated in the program and submit a report to MESSC within the fiscal year of 1995. As a part of this reporting procedure, the steering committee has decided to publish papers and some reviews by 27 research teams in a special issue of Intermetallics funded by MESSC.Most of the papers and reviews are from research teams having participated in the program for more than two years and have been continuously active in the field of intermetallics studies. All the papers and reviews contained in this special issue were peer reviewed. Less
