TL;DR: It is demonstrated that a subsequent homogenization heat treatment can effectively homogenize the AM alloy and remove the deleterious δ phase, and the combined experimental and modeling methodology can be extended to elucidate the phase evolution during heat treatments in a broad range of AM materials.

Charles Thomas,Peter Tait +1 more
TL;DR: In this paper, Alloy 625 was found to have suffered severe hardening and loss of ductility in service in a petrochemical plant for 50 000 h at 500°C and the mechanical properties of the material and the reasons for the change in properties were described along with remedial heat treatments.

Strain hardening in underaged INCONEL 718
TL;DR: In this paper, the deformation mechanism of a Ni[sub 3]Nb superalloy was investigated in terms of deformation microstructure in the case of underaged INCONEL 718 and it was shown that in a situation where the precipitate size is smaller than about 10 nm, deformation occurs by the passage of quadruplets or pairs of dislocations which shear the particles.
