Abstract:
ABSTRACT
Thermomechanical surface treatments such as high-temperature deep rolling and deep rolling with consecutive annealing were developed from conventional surface treatment
(deep rolling). The fatigue behaviour of thermomechanically treated quenched and tempered SAE 1045 was investigated using stress-controlled fatigue tests and compared with
conventionally deep-rolled conditions (deep rolled at room temperature). Residual stress and work-hardening effects in the modified surface layer before and after the
fatigue tests were investigated using X-ray diffraction methods.
KEY WORDS
Fatigue, thermomechanical surface treatment, deep rolling, residual stress
