Observation of the initial process of internal fracture in very high cycle fatigue in Ti-6Al-4V by synchrotron radiation μCT imaging

open access: yesNihon Kikai Gakkai ronbunshu, 2017
The initiation and growth of internal small fatigue cracks with around ten or several dozen μm in Ti-6Al-4V were nondestructively examined by using synchrotron radiation μCT at the large synchrotron radiation facility SPring-8.

Nutritional Potential, Phytochemical Content, In Vivo Antioxidant, and Antanemic Potential of Musa paradisiaca Flower

open access: yesFood Chemistry International, EarlyView.
After collecting Musa paradisiaca leaves, some were dried and others were used to produce aqueous extracts. The extracts and powders were characterized and then administered to rats made anaemic by PHZ. After 14 days of administration of the two samples, the rats were euthanized and it was observed that after 9 days of treatment, the aqueous extract ...

The gigacycle fatigue strength of steels: a review of structural and operating factors

open access: yes, 2018
It is known that usual frequency up to 100 Hz has no influence on the high cycle fatigue (HCF) strength of steels. However, in the very high cycle fatigue (VHCF) regime, the frequency effect is still unclear. Indeed, a high frequency can lead to heating,
