Effect of Friction Pressure on ZK60/Ti Joints Formed by Inertia Friction Welding
Journal of Materials Engineering and Performance, 2019The ZK60 Mg-based alloy (Mg-Zn-Zr alloy) and pure Ti were welded by inertial friction welding under friction pressures from 15 to 60 MPa. The mechanical properties and microstructures of the joints were investigated. The results show that the tensile strength of the welding joints increased with increasing friction pressure.

Phase transformations across high strength dissimilar steel inertia friction weld
Journal of Materials Processing Technology, 2008Microstructural variation across inertia friction welded Aermet 100 (ultra-high strength secondary hardening steel) and SCMV (high strength low alloy Cr-Mo steel) has been studied. Retained austenite was mapped in two dimensions across the inertia friction welds using synchrotron-X ray diffraction.

Ultrasonic NDE of solid-state bonds: Inertia and friction welds
Journal of Nondestructive Evaluation, 1988This paper discusses a number of special ultrasonic NDE problems of particular interest to inertia and friction welds, but most of the results can be readily applied to other similar or dissimilar solid-state bonds as well. One of the major problems associated with dissimilar bonds is the “blinding” effect of the strong interface reflection caused by ...

Strengthening mechanisms in an inertia friction welded nickel-base superalloy
Materials Science and Engineering: A, 2016Abstract This research investigated the strengthening mechanisms associated with the as-welded microstructure developed during inertia friction welding of dissimilar superalloys LHSR and Mar-M247. The weld interface and heat affected regions of the sample were analyzed using hardness indentation techniques and subsequently characterized using SEM ...

Modelling and simulation of the inertia friction welding of shafts
Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2007The commercial materials forming package DEFORM-2D is used to model the inertia friction welding (IFW) process with particular reference to aero-engine mainline drive shafts. Both representative and predictive modelling techniques are presented, and models are described for the welding of identical and dissimilar material/geometry combinations.

Process parameter analysis of inertia friction welding nickel-based superalloy
The International Journal of Advanced Manufacturing Technology, 2014A two-dimensional axisymmetric model for the inertia friction welding (IFW) of a nickel-based superalloy was developed. The influences from the axial pressure, initial rotational speed, and moment of inertia of the flywheel on the interface temperature and axial shortening were systemically examined. The analysis shows that the mechanical energy mainly

Sequential Transient Numerical Simulation of Inertia Friction Welding Process
International Journal for Computational Methods in Engineering Science and Mechanics, 2009Inertia 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, 2013ABSTRACTFatigue 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, 2014The 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 ...
