Abstract Scope Haynes 244® is a Ni-based superalloy that contains 40 vol. % of coherent Ni2(Cr,Mo,W) precipitates with lenticular shape. The deformation mechanisms of this alloy were investigated at 23ºC and 650ºC by means of micropillar compression tests in grains with different orientations suitably oriented for dislocation slip or twinning. The mechanical response of the grains oriented for slip at room temperature showed strain bursts, strain hardening and a fully elastic recovery upon unloading, that are indicative of dislocation plasticity. On the contrary, micropillars oriented for twinning did not show strain bursts or strain hardening and presented a large strain recovery upon unloading. In situ mechanical tests provided evidence of twin nucleation and thickening during compression, followed by detwinning during unloading. The deformation mechanisms of the micropillars deformed in both orientations and at both temperatures were carefully analyzed by transmission electron microscopy from lamellae extracted from the micropillars.
