Summary

To analyze the influence of near-surface materials states on the damage process during thermal fatigue loading, isothermal annealing experiments and thermal fatigue tests with hot-work tool steel AISI H11 (German grade X38CrMoV 5-1) in either shot-peened or hard turned surface condition were performed. Tension-compression thermal fatigue tests were carried out using a servohydraulic testing system, keeping the macroscopic strain of the gauge length constant, while triangular time-temperature cycles were applied. The temperature range was chosen in such a way that numbers of cycles to fracture between 1,000 and 10,000 were achieved. The development of plastic strain amplitudes as well as of mean stresses were analyzed during the tests.
