ABSTRACT

The development of oxide-dispersion strengthened (ODS) ferritic alloys is due, in part, to their beneficial physical characteristics. Ferritic alloys have an advantage over face-centered cubic alloys in many of the properties that are important in high-temperature applications. They are about 13% lower in density, have melting points about 100°C higher, and have lower coefficients of expansion and higher specific heats than face-centered cubic alloys. In addition, ferritic alloys tend to be more fabricable.
