In-situ SEM-EBSD investigation of the low-cycle fatigue deformation behavior of Inconel 718 at grain-scale

Journal of Materials Research and Technology, 2023
The low-cycle fatigue (LCF) deformation behavior of the Inconel 718 (IN718) specimen with micro-notch was investigated by an in-situ fatigue test inside a scanning electron microscope (SEM) combined with electron backscattered diffraction (EBSD).

Microscopic study of 5083-H321 aluminium alloy under fretting fatigue condition [PDF]

, 2011
Fretting occurs where there is small amplitude oscillating motion between solid surfaces in contact. With even small loads or prolonged operation, fretting may lead to crack initiation followed by fretting fatigue.

Analysis on Fatigue Crack Initiation and Fatigue Crack Propagation in a Gear

SMART MOVES JOURNAL IJOSCIENCE, 2018
An effective gear design balances strength, durability, reliability, size, weight and cost. Because of the advantage of gear, gearbox was used widely. But its fault also brought many losses of the production and society. It was necessary to research and analysis on the dynamical behavior of the gear system.
