TL;DR: In this article, a series of pure Al and mold steels were studied and a strong enhanced diffusion effect was revealed: the surface elements diffuse approximately several micrometers in depth into the substrate only after several bombardments.

TL;DR: In this paper, carbon-constraint Fe3N nanoparticles (Fe3N@C) with a unique core-shell structure are successfully realized through a facile 2-step process: fabricating Fe@C coreshell nanoparticles by DC arc-discharge method and subsequently converting them into Fe3Ns@C through chemical nitriding reactions.

TL;DR: In this paper, physical models and numerical simulations are applied to describe the thermal-dynamical processes of the high current pulsed electron beam (HCPEB) treatment, which reveals an ultrahigh heating/cooling rate in the order of 10 8 -10 9 K/s, as well as rapid melting and re-solidification within microseconds in time and micrometers in depth.

TL;DR: In this article, the surface modification of steels and magnesium alloy with high current pulsed electron beam (HCPEB) was investigated and the formation mechanisms of surface cratering and non-stationary hardening effect in depth were discussed based on the elucidation of non-equilibrium temperature filed and different kinds of stresses formed during pulsed beam melting treatment.

TL;DR: The high-resolution transmission electron microscopy images show that the void in CNTs, after cycling, is fully filled with pulverized SnS2 grains which have a shortened Li-ion diffusion path and enhanced surface area for interfacial redox reactions.
