Description	Transmission electron microscopy was performed to investigate the microstructure and precipitates in the annealed Co38Ni33Al29 ferromagnetic shape memory alloy. Apart from the dendritic secondary phase in the austenite matrix, micron-sized (up to 100 lm) fcc-based precipitates with partial c0 L12 ordering and containing none, one or three {111}p parallel twin planes were found. The orientation relation ship between the precipita tes and matrix was found to be Kurdjumov–Sachs. STEM–EDX analysis indicates that twinned and non-twinned precipita tes are Co-rich and Al- and Ni-deficient with respect to the matrix and with a lower Co/Al ratio for the latter. The 3D morphologies of precipitates were reconstructed with focused ion beam/scanning electron microscope dual-beam slice-and-view imaging, showing that the single {111}p plane twinned precipitates have a plate-like shape while the non-twinned precipitates are lath-like and often bent.
