Precipitation Kinetics and Morphology of Grain Boundary Carbides in Ni-Base Superalloy Haynes 282
Artikel i vetenskaplig tidskrift, 2020
Precipitation of grain boundary carbides in a mill-annealed Haynes 282 in the temperature range 650 degrees C to 1120 degrees C was investigated. The kinetics of M(23)C(6)was significantly faster than that of M6C. With increasing aging temperature, the morphology changes from continuous film to an interconnected brick wall structure and finally to discrete particles. No morphological changes were observed with aging time. Serrated grain boundaries formed during aging around 750 degrees C. The solvus temperature for both M(23)C(6)and M6C was approximately 1100 degrees C.
