A comparison of EBSD based strain indicators for the study of Fe-3Si steel subjected to cyclic loading
TL;DR: In this paper, an EBSD-based indicator for fatigue damage of a Fe-3Si steel was proposed, which revealed two different regimes depending on the applied total strain variation which is explained by the identification of the dislocations structures and their evolution.

Experimental study on spray and atomization characteristics under subcritical, transcritical and supercritical conditions of marine diesel engine
TL;DR: In this article, detailed characteristics of diesel spray and atomization based on marine engine scale have been studied under subcritical, transcritical and supercritical conditions, and the results show that the spray liquid periphery is quite smooth and stable with shorter penetration under supercritical condition, meanwhile, the jet of spray behaves as thinner periphery near the injector nozzle region and shows lower density at downstream region.
