Microtexture Study: Effect of Different Irradiation Sources on Zirconium and its Alloys

“…Many reports are indeed for irradiation on metallic materials [6] with the series of effects such as irradiation hardening, microstructure effects and residual stresses development [7][8][9][10][11][12][13][14]. Single crystal and poly-crystalline zirconium, and its ion irradiation effects in-terms of irradiation hardening, microtexture changes, misorientation increasing and residual stresses development are addressed and reported [11][12][13][14].Irradiation also creates crystal defects which are mainly point defects (interstitial defect) and it was quantified by a parameter known as displacements per atom (dpa) [6,15]. The present study was aimed to give comparative study of electron, ion and proton damage in Zr and its alloys in the form of single crystal and poly-crystalline materials.…”
