<p>Shear punch testing is a deformation technique that is used for the rapid evaluation of mechanical properties of materials. Its main advantage is that it requires much less material volume to create specimens for testing compared to other techniques, such as uniaxial tensile testing. This makes it particularly useful when the material availability for mechanical property evaluation is limited. Like many additive manufacturing methods that prioritize a reduction of component material to its minimum during fabrication processes, cold-sprayed metal coatings may fall into this situation. In general, results from shear punch testing of cold-sprayed materials are limited in the literature. Furthermore, most of the available data comes from researchers that have used shear punch testing for the evaluation of the ultimate shear and shear yield strengths of the material but have not reported on ductility results. In the present work, shear punch testing is used to evaluate the mechanical properties of cold-sprayed copper specimens, with a focus on ductility. Bulk copper and cold-rolled copper are used as reference materials. The results indicate that the effective ductility (<InlineEquation ID="IEq1"> <EquationSource Format="TEX">\(\varepsilon_{{{\text{eff}}}}\)</EquationSource> <EquationSource Format="MATHML"><math> <msub> <mi>ε</mi> <mtext>eff</mtext> </msub> </math></EquationSource> </InlineEquation>) may be used as a metric to evaluate intrinsic ductility when considering the observed trends among samples produced differently. Insights on the deformation stages and failure mechanism during shear punch testing, a topic that is not yet well addressed, are also provided. Finally, a comparison between the tensile and shear punch ductility measurements is made for the first time for cold-sprayed metals.</p>
