Influence of the dislocation density on hardening precipitation in Inconel© 625

Résumé

Inconel© 625 is a Nickel-base superalloy used in aerospace industry as turbine shrouds, spray bars, hydraulic tubing, armoring and thrust reversers systems [1]. One reason of its use is its high mechanical properties at high temperature. Inconel© 625 is strengthened by precipitation of γ″ phase, tetragonal Ni 3 Nb [1]. Since dislocations can influence precipitation [2], the precipitation of γ″ in Inconel© 625 was studied in samples submitted to cold straining to induce different dislocation contents before precipitation heat treatment.
