Feasibility of s3DXRD on a 50 um aluminium particle

Cold spray coating processes where small powder particles are projected with high velocity on a substrate which is made by plastic deformation of the particles.

To progress with numerical models (typically crystal plasticity finite element models), we aim to study in detail the mechanical behaviour of aluminium powder particles in compression. We plan to do a 4D experiment with Nanox2 (modified for compression) with the nanoscope.

The microstructure can be modified by heat treatment wich will change the grain size and the mosaicity (typically decrease from 5 deg to 1 deg). The particle size is about 30 microns so scanning 3DXRD is ideally suited. Do you think a teste could be run on a particle glued on a stick ? We aim to submit a proposal for the next call. The plan would be to map a particle but we need to check whether it will work before going ahead
