In-service damage of railway steel axles
O. Jasnìî, Tomaž Vuherer, Ju. I. Pindus, Andriy Sorochak, Ivan Samardžić, 2011, other scientific articles

Abstract: The influence of temperature and specimens undercut place on impact toughness of railway axle material in service is investigated. The obtained results show inversely proportional dependence of impact toughness on undercut radius of specimens. The decrease of test temperature from +20 to –40 ºC decreases significantly the impact toughness and portion of ductile fracture.
