Microstructure and Microtexture of Linear Friction Welded T1-6Al-4V
In this study,the microstructural features of linear friction welded Ti-6Al-4V joints have been investigated using X-ray diffraction (XRD),scanning electron microscopy (SEM) including electron backscatter diffraction (EBSD),and transmission electron microscopy (TEM). It has been found that the volume fraction of the β phase in the weld regions is much lower than that in the base metal, The chemical composition at the weld line region was found to be homogeneous suggesting that a martensitic transformation occurred during welding. Strong crystallographic textures were observed across the weld line, with the width of the strongly textured region being approximately 500 μm wide at the mid-section of the weld,and increasing away from the centre to about l000μm at the edge of the weld. A very strong 0001<1010> texture component was identified in the weld line zone and the thermomechanically affected zone.
