Effect of Solid Solution Treatment on Microstructure and Mechanical Properties of DS Superalloy DZ8

Effect of Solid Solution Treatment on Microstructure and Mechanical Properties of DS Superalloy DZ8

The microstructure of DZ8 after solid solution treatment at 1260 ℃ and 1240 ℃ was observed, and the tensile and stress rupture properties were compared. The results show that less than 1% γ+γ' eutectic remains in the microstructure of DZ8 after solid solution treatment at 1260 ℃, while incipien...
