Numerical simulation of inertia friction welding process of GH4169 alloy
Journal de Physique IV, 2004Friction welding is a solid state welding technology with good quality and high automation. It has been widely used in many industry fields especially in automobile and aerospace industry. Because of the characters of less process parameters and high automation, inertia friction welding is popular in many fields. In this paper, a 2-D thermo-mechanical

Thermal Relaxation of Residual Stresses in Nickel-Based Superalloy Inertia Friction Welds
Metallurgical and Materials Transactions A, 2011This article describes an experimental study aimed at characterizing the extent of residual stress relaxation during thermal treatment of inertia friction-welded alloy 720Li nickel-based superalloy welded tubular rings. In the as-welded condition, yield level tensile hoop stresses were found by neutron diffraction in the weld region along with axial ...

Electron microscopy characterization of the weld line zones of an inertia friction welded superalloy
Journal of Materials Processing Technology, 2011Abstract Microstructure in the weld line (WL) zone produced by inertial friction welding has been studied for a series of RR1000–RR1000 welds using transmission electron and scanning electron microscopy. A fully recrystallised fine grain structure was found to form throughout the WL zone, characterized by straight and smooth grain boundaries, high ...

A comparison of inertia friction welds in three nickel base superalloys
Materials Science and Engineering: A, 2006In this paper the microstructure, mechanical properties and residual stresses are compared for three inertia friction welded nickel-base superalloys. In contrast to alloy 720Li and RR1000, for Inconel 718 welding produces a precipitation free region leading to significantly reduced strength near the weld line.

Mechanical properties of the inertia friction welded aluminum/stainless steel joint
Welding in the World, 2019Mechanical properties of aluminum alloy/stainless steel joint including tensile strength, bending angle, impact toughness, and fatigue property were evaluated, and the effects of friction pressure and rotational speed were also discussed in this work. Results showed that the intermetallic compound (IMC) layer was formed at the bonding interface of the ...

Numerical Simulation of the Inertia Friction Welding Process of Dissimilar Materials
Metallurgical and Materials Transactions B, 2014Three-dimensional axisymmetric finite element analyses have been performed to analyze the coupled thermo-mechanical oscillatory transient problem of friction welding of two dissimilar hollow cylinders. The analysis included the effect of conduction and convection heat transfer implementing three independent variables specifically the welding time, the ...
