It is shown that the α-Mo matrix contains Al-enriched face-centred cubic precipitates which have a 4.12 Å lattice parameter, and exhibit a Kurdjumov–Sachs crystallographic orientation relationship with the matrix. Such precipitates could be responsible for the unusual behaviour of the pillars during compression tests.Atom probe tomographyElectron diffraction patternMo-alloy pillarsPrecipitatesTransmission electron microscopytext::journal::journal article::research article
