Fractography of the fatigue fracture surface of silumin irradiated by high-intensity pulsed electron beam

Abstract

Abstract. Irradiation mode has been revealed allowing to increase the silumin fatigue service life in three times, it was established that this fact is caused by the formation of multi-modal, multi-phase, submicro -and nano-structure able to lead to a significant increase in the critical length of crack.

Increase of Fatigue Life of Titanium VT1-0 after Electron Beam Treatment

“…Earlier in our papers [3][4][5] the significant increase in fatigue life of steels and alloys based on aluminum after electron beam processing was shown.…”

Mathematical Modelling Stress Distribution in a Metallic Plate with an Asymmetrical Notch

“…A sample stressed in a cantilevered manner was used for the purpose of research into high-and low-cycle fatigue of various structural steel classes [1][2][3][4]. Stress values around the notch-shaped stress raiser were calculated according to elasticity theory, methods of which are characterized by certain inaccuracy.…”

Structural Phase Transformations of the Surface Layer of SiC Ceramics Irradiated by Intense Electron Beam

“…Formation of such a state allows to localize plastic deformation of the material at the submicro and nano scales, provides uniform distribution of elastic stresses in the material, increases energy of nucleation of critical stress concentrators. It is especially important for brittle ceramic materials like silicon carbide [4]. Now the treatment by a low energy electron beam of submillisecond duration is one of the promising techniques for formation of a nanostructural state in a surface layer of material [5].…”
