Analysis of primary creep in simulated heat affected zone (HAZ) of two 9 - 12% Cr Steel grades

Analysis of primary creep in simulated heat affected zone (HAZ) of two 9 - 12% Cr Steel grades

The primary creep of the parent metal (α), inter-critical (α+γ), and coarse-grained (γ) microstructures of simulated weld heat-affected zone (HAZ) for the steels X20CrMoV121 and X10CrMoVNb91, aged for 4 320 hours (6 months) at 750 °C and 17 520 hours (2 years) at 650 °C was analyzed. The time and cr...
