This work compares the thermal responses of an α-iron and two carbon steels (C12 and C65 steel) via in-situ infrared thermography under 20 kHz ultrasonic tension-compression fatigue testing. The α-iron has only ferrite phase, and C12 and C65 steels

Metals used in industry for structures and aero-engine components are sometimes subjected to very high cycle fatigue (VHCF) damage during their working service. In this paper, a novel method is presented to determine the size and location of a circul

Many studies on the behaviour of very high cycle fatigue (VHCF) showed that there appear some distinguishable features compared with the low and high cycle fatigue. The understanding of mechanism of fatigue crack initiation in VHCF is very important.

International audience; In this study, the first signs of fatigue crack initiation are studied in the HCF domain on a body centered cubic Armco iron (with 80 ppm of carbon content). Some tests are performed on plate specimens through a piezoelectric
