Abstract Scope |
Small scale mechanical testing has significant benefits in probing microstructural features and in producing greater numbers of samples from finite volumes of material. In the nuclear field, smaller length scale specimens are necessary to account for the limited penetration depths of irradiations as well as to minimize overall radioactivity per specimen. Femtosecond laser machining is becoming an increasingly popular technique for rapidly and consistently fabricating micro to meso length scale test samples. Presently, the body of literature in this domain is sparse, and the utility of this technique, as well as small scale testing in general, is limited by the fidelity of the results. In this experiment, reduced geometry micro-mesoscale tensile samples were prepared via femtosecond laser machining to a range of gauge thicknesses and aspect ratios. The samples were pulled and analyzed in comparison to previous micro-mesoscale work in efforts to bridge the length scales in material property evaluation. |
