Nanoanalysis of precipitation in a modified Inconel 718 alloy

Proceedings, annual meeting, Electron Microscopy Society of America, 1994
The nickel-base superalloy Inconel 718 (IN718) is strengthened primarily by precipitation of two types of intermetallic phases in the austenite (γ) matrix: metastable γ' (cubic Ll2 structure) and γ" (tetragonal D022 structure) precipitates. Minor changes of the chemistry of the IN718 alloy can significantly affect its mechanical properties at high ...

Effect of rhenium on solidification of Inconel 718 alloy

Materials Science and Technology, 2005
AbstractThe effect of rhenium (Re) on the solidification of standard Inconel 718 (St-In718) has been investigated by using experimental alloys containing 2·4, 3·5, and 6·0%Re. Rhenium is one of the most powerful refractory elements that improve the high temperature mechanical properties of Ni base superalloys.

Optimization of Nd:YAG-Laser Welding Process for Inconel 718 Alloy

Materials Science Forum, 2007
Ni-based superalloys are extensively used in the manufacture of aircraft engine components because of their excellent heat-resistant and corrosion-resistant properties. The principal joining processes for Ni-based superalloys are TIG welding, MIG welding, submerged arc welding, electron beam welding, and CO2 laser welding.

Effect of Deformation Process on Superplasticity of Inconel 718 Alloy

Rare Metal Materials and Engineering, 2015
Abstract After grain refinement through hot-forging and δ-phase precipitation and recrystallization heat-treatment processes, the high temperature tensile experiments were carried out to investigate the effect of heat treatment and deformation process on the superplasticity of Inconel 718 alloy. Two tensile processes were used as follows: the maximum
