| Abstract Scope |
Controlling the microstructure and defects of materials through traditional methods like thermal annealing, which involves high temperatures and long processing times, often introduces additional challenges, such as thermoelastic strain and increased energy consumption. This necessitates exploring alternative techniques that can modify material properties without the drawbacks of conventional thermal treatments. The Electron Wind Force (EWF) could be such an athermal stimulus, which originates from the momentum transfer between the electron and lattice atoms. We observe that the Electron Wind Force (EWF) can effectively control grain orientation and modify the microstructure of various alloys. In addition, we will also discuss how the EWF can eliminate defects induced by cold rolling in a FeCrAl alloy in less than a minute at temperatures below 100°C, which typically require temperatures of 750°C and durations of up to 1.5 hours with traditional annealing. Also, EWF rejuvenates the performance of semiconductor devices and lowers radiation damage. |
