Journal ArticleDOI
Microstructure and evolution of mechanically-induced ultrafine grain in surface layer of AL-alloy subjected to USSP
TL;DR: In this paper, the authors investigated the UFG microstructures in the surface layer of an aluminum alloy 7075 heavily worked by ultrasonic shot peening and found that the grain subdivision into the subgrains was the main mechanism responsible for grain refinement.
Journal ArticleDOI
A review of recent studies on vortex-induced vibrations of long slender cylinders
Xiaodong Wu,Fei Ge,Youshi Hong +2 more
TL;DR: A review of the progress made during the past decade on vortex-induced vibration (VIV) of long slender cylindrical structures is given in this article, where a brief outline is given of numerical methods used in predicting the response of a long slender cylinder undergoing VIV.
Journal ArticleDOI
Strain-induced grain refinement of cobalt during surface mechanical attrition treatment
TL;DR: In this paper, the microstructural evolution during surface mechanical attrition treatment of cobalt (a mixture of hexagonal close packed (hep) and face-centered cubic (fcc) phases) was investigated.
Journal ArticleDOI
The formation mechanism of characteristic region at crack initiation for very-high-cycle fatigue of high-strength steels
TL;DR: In this article, the formation mechanism of FGA is proposed: Numerous Cyclic Pressing (NCP) between originated crack surfaces, which causes grain refinement at the originated crack wake and therefore the formation of fine-granular area (FGA).
Journal ArticleDOI
Propensities of crack interior initiation and early growth for very-high-cycle fatigue of high strength steels
TL;DR: In this article, a high carbon chromium steel with fine-granular-area (FGA) was used for fatigue testing and it was shown that the formation of FGA is responsible for a majority part of total fatigue life.
