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, 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, it was demonstrated that significant surface modifications can be generated by low-energy, high-current pulsed electron beam treatments in the "heating mode" (which does not melt the surface).

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 microstructure, hardness and corrosion resistance of commercially pure Ti treated by low energy high current pulsed electron beam (LEHCPEB) have been investigated in this article, where the thin near-surface melted layer rapidly solidified into β and subsequently transformed into ultrafine α′ martensite.
