  7. 5. Estimating inclusion content in high performance steels

    Author : Jens Ekengren; Jens Bergström; Christer Burman; Hans Nordberg; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Engineering; Materialteknik;

    Abstract : Non-metallic inclusions in steel pose a major problem for the fatigue resistance, especially regarding fatigue at very long lives corresponding to low cyclic stress levels, as well as being detrimental to material toughness and polishability.The largest inclusions are quite rare, which makes conventional detection methods timeconsuming if reliable results are to be obtained.
