Some phenomena regarding the superficial layer in case of the electron beam process

Autor: D. Dehelean, S. M. Ilii, A. Munteanu

Publikováno v: International Journal of Material Forming. 1:1363-1366

The electron beam that melts the workpiece surfaces, acts as concentrated energy tool. Starting from this consideration, we have analyzed some hypotheses regarding the energy flux distribution at the electron beam impact zone with the workpiece surfa

Residual Stress Determination in Near-Net Shape Formed Specimens Obtained by Thermal Spraying

Autor: N. Markocsan, P. Fogarassy, D. Dehelean, A. Manescu, F. Rustichelli

Publikováno v: International Thermal Spray Conference.

The aim of this work is to develop a finite element model that predicts the residual stresses in plasma sprayed parts formed on conical mandrels and removed by various means. The theoretical analyses and mathematical models are confirmed by X-ray dif
