摘要：

In this study, fibre laser welds of alloy Ti-6%Al-2%Sn-4%Zr-6%Mo have been characterised. It has been found that although the microstructure of the welds is important in predicting, properties, it is not enough to simply characterise the welds based on the microstructure, as crystallographic texturing is also important in determining mechanical properties. The texturing of the fibre laser welds is being characterized using EBSD mapping, with light microscopy to characterize the microstructure. This has been carried out for a weld that has been beat treated for 3 hours at 550 degrees C. At this temperature, relaxation of residual stress will occur, but changes to the microstructure will e minimal. It is planned that EBSD will now be carried out on the as received sample, and the results will be presented, along with a comparison with the licat treated weld.
