Numerical modelling of the linear friction welding process
International Journal of Material Forming, 2010Linear 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

Texture Evolution in Linear Friction Welded Ti-6Al-4V
Advanced Materials Research, 2010The linear friction welding (LFW) behavior of Ti-6Al-4V, a commercial α + β titanium alloy, was investigated using oscillation frequencies ranging from 30-70 Hz and axial pressures from 50-110 MPa. LFW samples were examined using electron backscattered diffraction (EBSD) to relate the texture to the welding parameters and to the estimated strain and ...

Mechanical Property and Microstructure of Linear Friction Welded WASPALOY
Metallurgical and Materials Transactions A, 2010The 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).

Linear friction welding of Ti6Al4V: Experiments and modelling
Materials Science and Technology, 2015Linear friction welding of the Ti6Al4V alloy is studied. A new definition of the energy input rate is proposed, based on an integration over time of the in-plane force and velocity; a strong correlation with the upset rate is then found. The effective friction coefficient is estimated to be 0·5±0·1 for varying frequencies and amplitudes, with only a ...

Linear Friction Welding of a Commercial Aluminum Alloy
Materials Science Forum, 2016The 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.
