Notes:
The formation behavior of γ″(Ni3Nb) precipitates in IN 718 alloy before and afterECAP(equal channel angular pressing) was investigated by microstructural observation and thehardness test. For the alloy examined before ECAP, the γ″ precipitates were formed only after agingtreatment at 720[removed info], whereas after ECAP, the γ″ precipitates were formed at the aging temperatures ofboth 600[removed info] and 720[removed info]. 600[removed info] is normally too low a temperature for γ″ precipitates to be formed incommercial IN 718 alloy, however, they were able to be formed due to severe plastic deformation byECAP. It was found that the ECAP process changed the formation behavior of the γ″ precipitates inIN 718 alloy
