Abstract


The MA956 alloy is a ferritic oxide dispersion strengthened alloy processed by mechanical alloying which exhibits a good high temperature oxidation resistance due to the capability to develop a compact and tightly adherent α-Al2O3 scale by thermal oxidation. The present study deals with the effects of the oxidation treatment (1,100°C/100 h) on its mechanical behavior at room temperature. It has been found that the oxide scale induces a decrease of the flow strength of the MA956/Al2O3 system with respect to that of scale-free specimens. This feature has been related to the formation during the preoxidation treatment of a high density of edge dislocations in a narrow zone of the substrate beneath the scale.
