Modeling of upset and torsional moment during inertia friction welding

Journal of Materials Processing Technology, 2016
Abstract Pipes of the heat treatable steel 42CrMo4 (AISI 4140) were joined by Inertia Friction Welding (IFW) while the diameter and the wall thickness of the pipe were varied. The machine parameters axial pressure and initial rotational velocity as well as the applied energy per cross section area were examined.

Sequential Transient Numerical Simulation of Inertia Friction Welding Process

International Journal for Computational Methods in Engineering Science and Mechanics, 2009
Inertia friction welding processes often generate substantial residual stresses due to the heterogeneous temperature distribution during the welding process. The residual stresses, which are the results of incompatible elastic and plastic deformations in weldment, will alter the performance of welded structures.

Fatigue crack growth characteristics of inertia friction welded Ti17 alloy

Fatigue & Fracture of Engineering Materials & Structures, 2013
ABSTRACTFatigue crack growth rates (FCGR) of the inertia friction welded Ti17 alloy joint was studied at room temperature (RT) and 400 °C at a stress ratio of 0.1. Microstructural analysis and mechanical tests were also carried out. The results show that at RT, FCGR of weld metal with recrystallisation microstructure was higher compared with the base ...

Inertia Friction Welding of Dissimilar Superalloys Mar-M247 and LSHR

Metallurgical and Materials Transactions A, 2014
The solid state inertia friction welding (IFW) process was used for the first time to join two dissimilar Ni-based superalloys, LSHR, a powder metallurgy alloy, and Mar-M247, a directionally solidified alloy. Extensive studies of the microstructure, phase composition, re-distribution of the alloying elements between the welded alloys, microhardness ...

Numerical simulation of inertia friction welding process of GH4169 alloy

Journal de Physique IV, 2004
Friction 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, 2011
This 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, 2011
Abstract 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, 2006
In 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, 2019
Mechanical 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 ...
