Transient behaviour of torque and process efficiency during inertia friction welding
Science and Technology of Welding and Joining, 2019Process efficiency is a crucial parameter for inertia friction welding (IFW). A new method is developed to determine the efficiency by comparing the workpiece torque used to heat and deform the joint to the total torque. Particularly, the former is measured by torque load cell attached to the non-rotating workpiece, while the latter is determined from

Microstructure evolution modeling of FGH96 superalloy during inertia friction welding process
Finite Elements in Analysis and Design, 2014In order to investigate the microstructure evolution of inertia friction welding process of FGH96 ring part, the dynamic recrystallization kinetic model of FGH96 superalloy was established and a two-dimensional axisymmetric coupled thermo-mechanical finite element model was developed using the MSC.Marc software.

Inertia-friction welding of SiC-reinforced 8009 aluminium
Journal of Materials Science, 1996Inertia-drive friction welding (IFRW) of an 8009 Al alloy (Al-8.5 Fe-1.7 Si-1.3 V, wt%) reinforced with 11 volume per cent SiC particles (8009/SiC/11p) has been investigated. Inertia-drive friction welds were made with constant energy at two levels of axial force.

Preliminary investigation of inertia friction welding B2 aluminides
Journal of Materials Science Letters, 1987An attempt is made to achieve inertia friction-welding in FeAl and NiAl samples, taking into account their intermetallics' compositions, extrusion parameters, and microstructural data. The energy required for the weld is stored in a rotating flywheel mass attached to one of the two pieces to be joined; when enough energy is introduced, the flywheel is ...

Residual Stresses in Inertia-Friction-Welded Dissimilar High-Strength Steels
Metallurgical and Materials Transactions A, 2009The welding of dissimilar alloys is seen increasingly as a way forward to improve efficiencies in modern aeroengines, because it allows one to tailor varying material property demands across a component. Dissimilar inertia friction welding (IFW) of two high-strength steels, Aermet 100 and S/CMV, has been identified as a possible joint for rotating gas ...

FE Modeling of the Inertia Friction Welding with a Modified Friction Law
Applied Mechanics and Materials, 2015The subject of this paper was the presentation of a holistic, fully-temperature-coupled FE model of inertia friction welding based on the modified friction law, which divided the friction welding process into beginning friction stage and steady equilibrium friction stage. At each of the stage Coulomb friction model and shear friction model were adopted

Mechanical Testing of Dual Alloy Inertia Friction Welded Shafts
Applied Mechanics and Materials, 2006The development of aeroengines with increasing thrust capabilities requires the development of shaft technology to deal with this greater power transmission, whilst still restricting their dimensions and weight. Modern aerospace drive shafts are predominantly of a single-alloy design and significant benefits could be obtained from using a dual alloy ...

Sequential Transient Numerical Simulation of Inertia Friction Welding Process
Volume 10: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B, and C, 2008Inertia 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.
