Microstructure Characteristics and Strengthening Behavior of Cu-Bearing Non-Oriented Silicon Steel: Conventional Process versus Strip Casting

Metals, 2021
Based on conventional hot rolling processes and strip casting processes, Cu precipitation strengthening is used to improve the strength of non-oriented silicon steel in order to meet the requirements of high-speed driving motors of electric vehicles ...

Propagation of surface initiated rolling contact fatigue cracks in bearing Steel [PDF]

, 2016
Surface initiated rolling contact fatigue, leading to a surface failure known as pitting, is a life limiting failure mode in many modern machine elements, particularly rolling element bearings.

Comparison of Precipitates and Texture Evolution in Nb-Bearing Grain-Oriented Silicon Steel Produced by Conventional Processing and Novel Twin-Roll Casting

Metals, 2020
The Nb-bearing grain-oriented silicon steel sheets were produced by conventional route and novel twin-roll casting route, respectively. The microstructure, texture and precipitate evolution were comparatively investigated by using electron backscattered ...

Building an information model in wheel-rail tribosystem control tasks [PDF]

MATEC Web of Conferences, 2021
The issues of filling the information model with data on the state of the wheel-rail tribosystem are considered. The “Program for modeling the transverse position of a wheelset in a track” is used, and the main modules of the program are described.

Rolling Nanoelectrode Lithography [PDF]

Micromachines, 2020
Non-uniformity and low throughput issues severely limit the application of nanoelectrode lithography for large area nanopatterning. This paper proposes, for the first time, a new rolling nanoelectrode lithography approach to overcome these challenges. A test-bed was developed to realize uniform pressure distribution over the whole contact area between ...

Determining the stress-strain state of the elastic clip of rail fastening W30

Вестник Научно-исследовательского института железнодорожного транспорта
Introduction. The article provides performance evaluation of the elastic clip of intermediate rail fastening during their strength characteristics assessment. In modern conditions this issue is solved by modelling using the finite element method. In order

Analysis of rolling group therapy data using conditionally autoregressive priors [PDF]

, 2011
Group therapy is a central treatment modality for behavioral health disorders such as alcohol and other drug use (AOD) and depression. Group therapy is often delivered under a rolling (or open) admissions policy, where new clients are continuously ...

On Effective Actions for the Bosonic Tachyon [PDF]

, 2003
We extend the analysis of hep-th/0304045 to the bosonic case and find the one-derivative effective action valid in the vicinity of rolling tachyons with an energy not larger than that of the original D-brane.
