Thermodynamic Processes and Phenomena Induced by High Current Pulsed Electron Beam
Due to the special heating mode of High Current Pulsed Electron Beam (HCPEB) irradiation, intense stresses such as thermoelastic stress, quasi-static stress, and shock wave stress can be generated by a dynamic thermal field. A dynamic thermo-stress is the origins of these stresses. The simulations for non-melting and melting modes are respectively compared with related phenomena such as bending, surface plastic deformation, and residual stress (non-melting mode, quasi-static stress-related), crater formation, depth distribution of microhardness, fragmentation of pearlites (melting mode, shock-stress wave-related).
