Assessing Fracture Surface Ductility by Confocal Laser Scanning Microscopy
Merson, E. D.; Danilov, V. A.; Linderov, M. L.; Merson, D. L.; Vinogradov, Alexey (Journal article; Peer reviewed, 2018)Hitherto there is no generally accepted quantitative parameter which, on the one hand, would reliably characterize the ductility of the whole fracture surface, and, on the other hand, could be relatively quickly measured. ... -
Effect of precipitates on static and fatigue strength of a severely forged aluminum alloy 1570C
Avtokratova, E. V.; Sitdikov, O. Sh.; Latypova, O. E.; Markushev, M. V.; Linderov, M. L.; Merson, D. L.; Vinogradov, Alexey (Journal article; Peer reviewed, 2018)Bulk billets from commercial ingots of the alloy 1570C with different size of aluminides of transition metals were subjected to severe deformation up to the equivalent strain e~24 via multi-step isothermal forging (MIF) ... -
Features of the Hydrogen-Assisted Cracking Mechanism in the Low-Carbon Steel during Ex- and In-situ Hydrogen Charging
Merson, E. D.; Myagkikh, P. N.; Poluyanov, V. A.; Merson, D. L.; Vinogradov, Alexey (Journal article, 2018)Hydrogen embrittlement has been intensively studied in the past. However, its governing mechanism is still under debate. Particularly, the details of the formation of specific cleavage-like or quasi-cleavage fracture ... -
Phenomenological approach towards modelling the acoustic emission due to plastic deformation in metals
Vinogradov, Alexey; Yasnikov, IS; Merson, D. L. (Journal article; Peer reviewed, 2019)Considering acoustic emission (AE) as a phenomenon reflecting the elastic energy dissipation process in deforming metals, a simple yet self-consistent model is proposed to account for the AE behaviour accompanying ... -
Using acoustic emission signal categorization for reconstruction of wear development timeline in tribosystems: Case studies and application examples
Rastegaev, I. A.; Merson, D. L.; Danyuk, A. V.; Afanasyev, M.A.; Vinogradov, Alexey (Journal article; Peer reviewed, 2018)The purpose of this work is to demonstrate how a new acoustic emission (AE) technique can be used to monitor friction surface degradation in a four-ball tribosystem under different types of lubrication. The AE method is ...
