  • Effect of operating temperature on microstructure and creep resistance of 20CrMoV 121 steel
    Vodopivec, Franc, 1931-2021 ...
    The degradation process of an X20CrMoV 121 steel with an initial microstructure of tempered martensite was investigated. The effects of the change of microstructure type, and of the carbide particles ... size and distribution were determined. Accelerated creep tests showed that the change of the mode of distribution of the carbide particles decreases more strongly due to creep resistance than the increase of the particle-to-particle distance. In the temperature range 550 [compositum]C to 800 [compositum]C, for annealing times from 2 h up to 1344 h, the hardness decreases faster at lower temperatures. It is possible to determine with sufficient reliability whether the steel's resistance to creep deformation was reduced below a safe level with non-destructive verification of the steel's microstructure and hardness.
