The recently developed simulative accelerated creep testing (ACT) on a Gleeble thermal mechanical simulator allows the microstructural transformation of creep-resisting materials in a relatively short time (less than 100 hours) to a state resembling

A deep cryogenic heat treatment (DCT) was applied to X37CrMoV5 steel, which included soaking at -160°C for 12 and 30 hours followed by tempering at 180°C. Microstructures were compared with those after conventional heat treatment (HT). Microstructu

Creep resistance of the steel depends on chemical and structural composition and structural stability. Therefore it is necessary to check microstructural changes in material during the long-term service, however the necessary material analyses are ge
