Modelling the linear friction welding of titanium blocks

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2000
Abstract Analytical and numerical models of linear friction welding of Ti6Al4V (numbers indicate wt.%) are established to predict temperature rises during the initial phase of the process, which is of importance in forming sound welds. Both model predictions are compared with experimental data.

Linear Friction Welding of IN718 to Ti6Al4V

Materials Science Forum, 2016
Linear friction welding (LFW), an emerging automated technology, has potential for solid-state joining of dissimilar materials (bi-metals) to enable tailoring of the mechanical performance, whilst limiting the assembly weight for increased fuel efficiency.

Numerical modelling of the linear friction welding process

International Journal of Material Forming, 2010
Linear friction welding (LFW) is a solid-state joining process applied to non-axisymmetric components. LFW involves joining of materials through the relative reciprocating motion of two components under an axial force. In such process the heat source is given by the frictional forces work decaying into heat determining a local softening of the material

Linear Friction Welding

2017
The current chapter discusses an application arising in the process of linear friction welding applied in metallurgy. In the first place a one-dimensional non-local model defined in the half-line is constructed in order to describe the evolution of the temperature within the welding region.

Linear Friction Welding of a Single Crystal Superalloy

Materials Science Forum, 2012
The effect of forging pressure on linear friction welding (LFW) behaviour of a single crystal Ni-based superalloy was investigated. Crystal orientations of the specimens were controlled and results indicated that welding success is dependent on proximity of the oscillation direction to the <011> direction.

Residual Stresses in Linear Friction Welded IMI550

Journal of Neutron Research, 2004
Residual stresses in linear friction welded (LFW) IMI550 have been determined by means of high energy synchrotron X-ray diffraction. Specimens were studied in the as-welded, and three different post weld heat treated conditions. Mid-thickness-mid-width line scans were recorded across the weld line in the three principal directions ...

Mechanical Property and Microstructure of Linear Friction Welded WASPALOY

Metallurgical and Materials Transactions A, 2010
The mechanical properties and microstructural evolution of WASPALOY joined by linear friction welding (LFW) were investigated in this study. In-situ temperature measurements using thermocouple probes indicated exposure of the weld area to a temperature of at least 1400 K (1126 °C).

Welding repair by linear friction in titanium alloys

Materials Science and Technology, 2009
Gas turbines for aeroengines are generally manufactured by attaching individual blades into slots in the disk. However, an alternative design consists in producing bladed disks, where disk and blades are a single piece. Previous studies have shown that linear friction welding is a technology which fits well for this application.

Linear Friction Welding of a Commercial Aluminum Alloy

Materials Science Forum, 2016
The mechanical properties and microstructure of a solid-phase compound produced by linear friction welding (LFW) of commercial Al-4.4%Cu-0.5%Mg-0.4%Mn-0.5%Ag alloy have been studied. The samples of Al-Cu-Mg-Ag alloy were produced by ingot metallurgy and subjected to thermomechanical treatment to get different initial microstructures.
