Eddy Current Testing of Fatigue Degradation of Metastable Austenitic Steel under Gigacycle Contact-Fatigue Loading

Autor: L. Kh. Kogan, R. A. Savrai

Publikováno v: Russian Journal of Nondestructive Testing. 57:393-400

During operation, the surfaces of parts made of austenitic chromium–nickel steels are subjected to intense cyclically repeated contact loads, including shock loads. Therefore, an urgent task is to study contact fatigue and develop methods for nonde
