Abstract Based on the infrared measurement of the self-heating process of40CrNiMoA alloy steel specimens during low cycle fatigue, discussions were made ofthe cyclic variation of self-heating temperature increment as well as the relationshipof their surface temperature distribution with cycles, controlled strain level andloading frequency. The energy dissipation during fatigue damage evolution in a cyclehas also been analysed.
