Cyclic softening in the MA956 ODS steel
Original language description
High chromium steel (MA956) prepared by mechanical alloying (MA) and strengthened by fine oxide dispersion was investigated. Corse microstructure with grains larger than 100 mm was revealed. The oxide distribution was analyzed by the means of transmission electron microscopy. Specimens were cycled with constant strain amplitude and strain rate at room temperature. Continuous cyclic softening consisting of three stages was measured. Short initial stage of rapid cyclic softening was followed by relativelylong stage where the softening rate is constant and lower than the one measured in the first stage. In last stage, cyclic softening rate again increases, but this rather influenced by the growth of long cracks. Cyclic softening and role of oxide dispersion was discussed in relation with microstructural observations. Moreover, microstructure and cyclic softening of the MA956 steel is compared with different ODS steels.
