“…Hence the effect of load frequency may be very small or vanish in very high strength steels or alloy steel. This fact has been supported by author [20] and many other experiments [21][22][23][24][25][26] .…”

There is a critical roughness for the specimen, depending on the hardness of tested metallic material. A larger roughness than the critical one will lead to a premature fracture. 3. The frequency effect is obvious for the low strength steel, however, is prone to vanish for the very high strength steel. 4. The very high cycle fatigue will be more sensitive to the inclusion size as the strength increases and the S/N curve character is strongly related to the size of the inclusion.

“…Many researchers have quantitatively investigated the effect of many factors on fatigue behaviours. The fatigue lives of the bearing steel GCr15 and Cr‐Ni‐Mo‐V steel exhibit sensitivity of loading frequency, while those of AISI‐SAE 52100, JIS SNCM439, and spheroidal graphite cast iron do not. Morrissey et al reported that the effect of frequency on the fatigue behaviours of Ti‐6Al‐4V is negligible under stress ratio R = −1.…”

Rotary‐bending fatigue tests of Ti‐6Al‐4V alloy at very high‐cycle regime were performed in air and 3.5% NaCl solution, respectively. The S‐N curves exhibited the characteristic of horizontal asymptote (traditional fatigue limit) in laboratory air, while a lower fatigue limit was shown in 3.5% NaCl solution after around 3 × 108 cycles. The decrease of fatigue life was due to the generation of small surface defects in comparison with that in air. These defects were ascribed to the hydrogen‐induced cracking and fatigue loading. The number of fatigue crack initiation sites decreases with increasing cycles. Only one crack origin site, dominated by slip mechanism, exists in each specimen at very high‐cycle regime. The existing experimental S‐N data of Ti‐6Al‐4V alloy from very high‐cycle fatigue tests were also reviewed. It was shown that the fatigue life (R = −1) of Ti‐6Al‐4V alloy was predominantly influenced by the microstructure and not strongly sensitive to the loading mode and frequency (in the range from 52.5 Hz to 20 kHz) under air condition at room temperature.

“…It enables the economic and less time-consuming assessment of the melt cleanliness [14] due to the high testing frequency during fatigue testing [20,21,22,23,24,25,26]. In addition, this method enables the in situ investigation of the influence of nonmetallic inclusions on the crack initiation by various complementary non-destructive testing methods, i.e.…”
