Mechanical testing of materials at smaller length scales enables targeted studies into microstructural features while considering the limitations and handling of irradiated samples. Typical small scale sample preparation techniques require the use of focused ion beam milling which can be both time consuming and infeasible for samples larger than a few tens of microns. Traditional mesoscale machining techniques generally leave a surface finish unsuitable for samples in the tens of microns. This results in an observable data gap and concern in the fidelity and extendibility of small-scale data to bulk scale applications. Femtosecond laser machining enables the rapid and consistent fabrication of micro-mesoscale samples that can fill this data gap. This presentation showcases data obtained from a series of micromechanical tensile samples machined to a range of geometries <100um via femtosecond laser machining. The objective is to elucidate potential size effects in investigating samples at reduced geometries.
