“…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.…”

The comparative study of Ga+ion, Nb+ion, proton and electron (H+and e-) irradiation on single crystal and poly crystal Zirconium (Zr), characterised in terms of misorientation profile change, EBSD maps or microtexture, XRD residual stresses development and irradiation hardening effect. It was concluded that the rate of damage is varying with respect to irradiation source. In the present study both the Zr and its alloys were used to conclude this main objective.

The mechanical response of metallic materials results from a complex hierarchy of deformation mechanisms across length scales. The need to understand these mechanisms independently has driven the miniaturization of testing samples, including small scale samples and single crystal micropillars. However, difficulties in machining and testing small samples have hampered the evaluation of the mechanical response of mesoscale samples with dimensions between tens to hundreds of microns. This paper innovates with a simple approach for the manufacturing and test of dog-bone specimens with a minimum gauge width up to 50 μm. The results demonstrate a pronounced sample size effects on the mechanical response for the dimensions analysed and highlights the need to advance the characterization of mesoscale samples. We also demonstrated the capability of testing the tensile response of single crystals from engineering alloys.
