GH132 Alloy properties：

After long-term aging at 650°C, G phase and cellular η phase were precipitated at the grain boundary, and the η phase showed Wechsler microstructure after 6000 h. When the alloy composition exceeds the specifications of the technical standard or some process is not in order, an excess of η, G and o phases can occur, and an abnormal cellular γ phase appears.

GH132 Uses of alloys：

HuaNickel GH132 alloy has been used in the manufacture of fasteners for aviation and aerospace engines.

GH132 Process performance:

Welding process: The alloy has satisfactory welding performance, and can be welded by argon arc welding, spot welding, and seam welding. The alloy is welded in a solution state, and the aging treatment is carried out after welding. The strength coefficient of the TIG welding butt sonotre with aging treatment after welding is greater than 90%.
