effect of filler metals on solidification cracking susceptibility of al alloys 2024 and 6061
Journal of Materials Processing Technology, 2019Co-Authors: Tayfun Soysal, Sindo KouAbstract:Abstract The effectiveness of filler metals in reducing solidification cracking in welds of 2024 Al and 6061 Al was examined, these two Al alloys being highly susceptible to solidification cracking. The effectiveness was evaluated by the Transverse Motion weldability (TMW) test. 2024 Al was welded with filler metals 2319 Al, 4043 Al and 4145 Al. 4043 Al and 4145 Al both reduced cracking effectively, but 4145 Al was significantly better. 6061 Al was welded with filler metals 4043 Al and 4943 Al (a new alloy designed to increase the weld strength of the 6000-series alloys), and the effectiveness was similar. Micrographs and curves of temperature T vs. fraction solid fS of the weld metals were used to help explain the test results.

Magnetic skyrmion field-effect transistors
Applied Physics Letters, 2019Co-Authors: Ik-sun HongAbstract:Magnetic skyrmions are of considerable interest for low-power memory and logic devices because of high speed at low current and high stability due to topological protection. We propose a skyrmion field-effect transistor based on a gate-controlled Dzyaloshinskii-Moriya interaction. A key working principle of the proposed skyrmion field-effect transistor is a large Transverse Motion of skyrmions, caused by an effective equilibrium dampinglike spin–orbit torque due to spatially inhomogeneous Dzyaloshinskii-Moriya interaction. This large Transverse Motion can be categorized as the skyrmion Hall effect but has been unrecognized previously. The proposed device is capable of performing multibit operation and Boolean functions and thus is expected to serve as a low-power logic device based on magnetic solitons.Magnetic skyrmions are of considerable interest for low-power memory and logic devices because of high speed at low current and high stability due to topological protection.

Transverse drag of slow light in moving atomic vapor
Optics letters, 2020Co-Authors: Yakov Solomons, Chitram Banerjee, Slava Smartsev, Jonathan E. Friedman, D. Eger, Ofer Firstenberg, Nir DavidsonAbstract:The Fresnel-Fizeau effect of Transverse drag, in which the trajectory of a light beam changes due to the Transverse Motion of the optical medium, is usually extremely small and hard to detect. We observe Transverse drag in a moving hot-vapor cell, utilizing slow light due to electromagnetically induced transparency (EIT). The drag effect is enhanced by a factor 3.6×105, corresponding to the ratio between the light speed in vacuum and the group velocity under EIT conditions. We study the contribution of the thermal atomic Motion, which is much faster than the mean medium velocity, and identify the regime where its effect on the Transverse drag is negligible.

the Transverse Motion of solids in rotating cylinders forms of Motion and transition behavior
Powder Technology, 2001Co-Authors: Jochen MellmannAbstract:Mathematical models were developed to predict the transitions between the different forms of Transverse Motion of free-flowing bed materials in rotating cylinders: sliding, surging, slumping, rolling, cascading, cataracting and centrifuging. Model calculations of the limits between these types of bed Motion compare well with measurements of experimental rotating cylinders as well as published results from industrial practice. The Motion behavior can be represented on a Bed Behavior Diagram that plots wall friction coefficient and Froude number against the filling degree. From this study, scaling criteria for the bed behavior were found to be the Froude number, filling degree, wall friction coefficient, ratio of particle to cylinder diameter, angle of internal friction, and static and dynamic angles of repose. The transition criteria worked out and the Bed Behavior Diagram provides the user of rotary kilns the possibility to estimate the type of Motion of the bed materials used from measured particle characteristics. As a result, the bed behavior can be influenced through selection of operating variables such as rotational speed and filling degree or installation of lifting bars and flights.
