Abstract
AbstractCreep tests have been performed on a commercial, 1Cr-0.5Mo low-alloy ferritic steel. Changes in carbide composition at 823 K have been measured as a function of exposure time using a scanning transmission electron microscope with an energy-dispersive X-ray analysis facility. The changes in the substitutional solute element concentrations in cementite are reported, and it is suggested that these changes could provide an aid to the estimation of effective exposure temperature for use in determining the remanent life of components made from this steel.
