After machining the samples, residual stresses on one set of uncracked deposited tracks (S1-S3) were measured using X-ray diffraction technique, based on sin 2y method [17] which uses the planes of crystal lattice as an atomic scale "strain gauge." X-ray residual stress analysis is based on the angular shift of diffraction lines due to stresses [18].
It was found that X-ray diffraction patterns of samples of vanadium-containing gel, taken within the range from 5 to 25 minutes, are identical.
The results obtained "provide refined and in some cases new identifications of the minerals in this first X-ray diffraction analysis on Mars," a NASA researcher said.
