Combining photolithographic silicon etching with the pressure infiltration of molten metal into porous preforms at elevated temperature enables the production of shaped 2D or 2.5D structures out of silver, gold, copper and their alloys [1]. This approach merges advantages of lithography and casting to create a route for the reproducible processing of engineering metal components or samples with excellent dimensional control and the capacity for high production rates. Using this approach, we demonstrate the production of monocrystalline tensile specimens, such as the deformed pure silver sample in the figure below. These tensile samples, the surface of which is unaffected by focused ion beam milling artefacts, have a diameter selected in the range from 2.5 μm to 13 μm, a taper of 1° or less, and an aspect ratio in excess of four. Data from tests conducted on these microtensile samples under the scanning electron microscope in displacement control and at steady temperature up to 400 °C are compared with corresponding data from bulk counterpart samples of the same metals processed similarly. Results from the tests show that microcast fine-scale metal samples exhibit characteristics of confined plasticity coupled with a strong influence of crystal orientation. Specifically, yield is shown to be governed chiefly by the sample size, while the rate of work hardening is primarily a function of crystal orientation. Deformation of microcast silver samples proceeds with a strong component of burst-like, intermittent plasticity, the signature of which confirms with the expected power law at low burst intensities, while showing an exponential complementary burst size distribution at higher burst intensities.
