Solute atom migration in GH4169 superalloy under electrostatic fields

International Journal of Minerals, Metallurgy, and Materials, 2013
Electric field treatment (EFT) was applied on GH4169 alloy during aging at 500–800°C to investigate the microstructure and property variation of the alloy under the action of EFT. The results demonstrate that the short-distance diffusion of Al, Ti, and Nb atoms can be accelerated by EFT, which results in the coarsening of γ′ and γ″ phases.

Experimental Study on Thermostatic Cutting Nickel-Base Superalloy GH4169

Advanced Materials Research, 2010
Nickel-base super alloy GH4169 is difficult to cutting and tool wear is very serious, because of its high strength, poor thermal conductivity, and serious work-hardening. In order to choose reasonable cutting parameters as to improve the processing efficiency, the cutting experiments were crarried out and the changes of workpiece material physical in ...

Investigations on Belt Grinding of GH4169 Nickel-Based Superalloy

Advanced Materials Research, 2014
The majority of aero-engine components are designed and manufactured with nickel-based superalloy GH4169 in mind. There is little information available in the literature related to belt grinding processes of aero-engine components. Up to now, limited research has been reported in the use of belt for grinding aero-engine components made of nickel-based ...

Deformation behaviour of GH4169 nickel based superalloy in isothermal compression

Materials Science and Technology, 2008
Isothermal compression of the GH4169 nickel based superalloy was carried out at a Thermecmaster-Z simulator at deformation temperatures of 930–1050°C at intervals of 20°C, strain rate of 0·1–50·0 s−1 and maximum height reduction of 60·0%. The deformation behaviour of the GH4169 superalloy in isothermal compression was characterised based on the stress–

Diffusion bonding of AlCoCrFeNi2.1 eutectic high entropy alloy to GH4169 superalloy

Materials Science and Engineering: A, 2020
Abstract Eutectic high entropy alloys possess both excellent plasticity and high strength. To explore their potential engineering applications, the diffusion behavior of elements, the interfacial microstructure and shear strength of the diffusion bonded joint between AlCoCrFeNi2.1 eutectic high entropy alloy and GH4169 superalloy were studied.

Effect of prestress on cutting of nickel-based superalloy GH4169

The International Journal of Advanced Manufacturing Technology, 2018
In view of the serious tensile residual stress distributed on the machined surface in cutting nickel-based superalloys GH4169, the prestressed cutting method has been adopted to actively control the surface residual stress. Numerical and experimental studies have been performed to investigate the effect of prestress on the cutting of GH4169.

Investigation on strain dependence of metadynamic recrystallization behaviors of GH4169 superalloy

Vacuum, 2018
Abstract The metadynamic recrystallization (MDRX) behaviors of a solid-solution GH4169 superalloy were studied by two-pass hot compression tests. The effects of pre-strain (deformation degree of the first pass) on MDRX behaviors were analyzed. Results show that the MDRX behaviors intensely depend on the pre-strain.
