Journal ArticleDOI
Effect of surface roughness on step-wise S–N characteristics in high strength steel
TL;DR: In this article, the effects of surface roughness on crack initiation mechanism and associated step-wise S-N characteristics were studied, and a fish-eye was always observed in subsurface crack initiation.
Journal ArticleDOI
Statistical duplex S–N characteristics of high carbon chromium bearing steel in rotating bending in very high cycle regime
Tatsuo Sakai,B. Lian,Mitsuhiro Takeda,Kazuaki Shiozawa,Noriyasu Oguma,Yasuo Ochi,Masaki Nakajima,Takashi Nakamura +7 more
TL;DR: In this article, the statistical fatigue properties of high carbon chromium bearing steel (JIS: SUJ2) in rotating bending were analyzed by applying the concept of mixed-mode Weibull distribution.
Journal ArticleDOI
Experimental reconfirmation of characteristic S-N property for high carbon chromium bearing steel in wide life region in rotating bending
Tatsuo Sakai,Mitsuhiro Takeda,Kazuaki Shiozawa,Yasuo Ochi,Masaki Nakajima,Takashi Nakamura,Noriyasu Oguma +6 more
TL;DR: In this article, a series of fatigue tests were performed by means of same type fatigue testing machines and same type of fatigue specimens in a definite high carbon chromium steel for the use of bearing as a collaborative study by the authors.
Journal ArticleDOI
Defect-dominated fatigue behavior in type 630 stainless steel fabricated by selective laser melting
TL;DR: In this paper, the authors compared the fatigue behavior of type 630 (17-4 pH) stainless steel specimens fabricated by selective laser melting (SLM) with those of the conventionally-melted (CM) type 630.
Journal ArticleDOI
Experimental estimation of crack initiation lives and fatigue limit in subsurface fracture of a high carbon chromium steel
TL;DR: In this paper, two-step variable amplitude loading tests were conducted using fine-particle bombarded specimens of a high carbon chromium steel, JIS SUJ2, in order to clarify subsurface crack initiation life and fatigue limit.
