Current Limitations of High-Temperature Alloys in Practical Applications

摘要

There are several engineering systems which require materials of construction to tolerate elevated temperatures, and aggressive environments of one kind or another; and where, furthermore, the performance of the system is limited by the materials capability. This paper reviews a number of these systems, drawn principally from the electric power industry, and describes both the current approaches to improving the materials capability, and potential directions for research and development for the future. Particular emphasis is given to cases where the problems related to oxidation and high-temperature corrosion are of major importance.
