Micropillar compression testing of powders
An experimental design for microcompression on individual powder particles is proposed as a means of testing novel materials without the challenges associated with consolidation to produce bulk specimens. This framework is demonstrated on an amorphous tungsten alloy powder, and yields reproducible measurements of the yield strength (4.5 +/- A 0.3 GPa) and observations of the deformation mode (in this case, serrated flow by shear localization).
