Effect of Two-stage Aging Time on Microstructure and Mechanical Properties of GH4706 Superalloy

Effect of Two-stage Aging Time on Microstructure and Mechanical Properties of GH4706 Superalloy

The effects of two-stage aging time at 720 ℃ and 620 ℃ on the η phase and γ'/γ'' phase of GH4706 superalloy were studied using optical microscopy， scanning electron microscopy， etc. The room temperature strength， impact， and creep rupture life of the material were tested under differe...
