Résumé : Dispersion of fine particles of refractory oxide (ThO//2) induces strengthening and thus improved mechanical properties in Ni-Co alloys at high temperatures. This study demonstrates that adding small proportions of MgO significantly improves the behavior of the dispersed ThO//2 without hampering densification of the material when sintering. Sintering at temperatures from 900 to 1300 degree C was carried out for an hour under hydrogen followed by thermal treatment at 1300 degree C for 24 h.
