Influences of Manufacturing‐Related Microstructural Variations on Fatigue in Carbide‐Rich Tool Steels

Abstract

Here, D is a factor depending on the defect location (surface or bulk), while α depends on the hardness. Studies by Meurling et al., [12] Sohar et al., [13][14][15][16][17][18][19][20] Kazymyrovych et al., [21,22] Ekengren et al., [23] Bergström et al., [24] and Randelius et al. [25,26] investigated the influences of microstructure properties on HCF (N G ¼ 10 7 ), very-HCF (VHCF) (N G ¼ 10 8-9 ), and ultra-HCF
