Abstract In this study, we investigate detailed electron dynamics in strong guide‐field reconnection (the normalized guide field is ∼1.5). This reconnection event is observed by the Magnetospheric Multiscale (MMS) spacecraft at the center of a fl

Abstract Agyrotropic electron distributions are frequently taken as an indicator of electron diffusion regions of magnetic reconnection. However, they have also been found at electron‐scale boundaries of the non‐reconnecting magnetopause and are

Various types of plasma waves are generated around electron diffusion regions (EDRs). Here the authors show electron Bernstein waves (EBWs), at the electron-scale boundary of the Hall current reversal near EDR, are sufficiently strong to diffuse elec

We report local secondary magnetic reconnection at Earth’s flank magnetopause by using the Magnetospheric Multiscale observations. This reconnection is found at the magnetopause boundary with a large magnetic shear between closed magnetospheric fie

Vortex-induced reconnection originates from non-linear vortex flows due to Kelvin-Helmholtz instability in the Earth’s magnetosphere. Here, the authors perform a large-scale kinetic simulation to unveil dynamics of the vortex-induced reconnection a

Three types of post-weld heat treatment (PWHT), i.e. solution treatment + primary aging + secondary aging (I), secondary aging (II), and primary aging + secondary aging (III), were applied to a single crystal nickel-based superalloy joint made with

In this study, the microstructure evolution of AISI 321 stainless steel during linear friction welding (LFW) was investigated. The results show that LFWed AISI 321 joint has a distinct weld zone (WZ) and thermo-mechanically affected zone (TMAZ). Th

Friction stir spot welding (FSSW) is a very useful variant of the conventional friction stir welding (FSW), which shows great potential to be a replacement of single-point joining processes like resistance spot welding and riveting. There have been m
