Abstract
Oxide Dispersion Strengthened (ODS) nickel-base alloys have good strength and corrosion resistance at high temperatures and are produced from their constituent elements in the form of mechanically alloyed powders which are subsequently hot extruded and directionally recrystallised. The ODS alloy MA 754, the subject of this study, consists of a single phase solid solution Ni-Cr matrix containing 1.0 vol.% finely distributed particles of yttria. These stable oxide particles give the alloy strength up to a relatively high proportion of its melting point and the elongated grain structure with a preferred <001> orientation leads to good thermal fatigue resistance.
