Abstract

In the present paper are mentioned the results of thermomechanical fatigue tests of 16Mo5.3b steel test specimens, from metallographic point of view and from microstructural view of starting and growing cracks at thermal fatigue. Are presented cross and longitudinal sections through the test specimens highlighting the cracks growing.
