abstract = {Although laser welding is probably the most used joining
technique for NiTi shape memory alloys there is still alack
of understanding about the effects of laser welding
parameters on the microstructural induced changes: inboth
the heat affected and fusion zones martensite may be
present, while the base material is fully
austenitic.Synchrotron X-ray diffraction was used for fine
probing laser welded NiTi joints. Through Rietveld
refinementthe martensite and austenite phase fractions were
determined and it was observed that the martensite
contentincreases towards the weld centreline. This is
related to a change of the local transformation temperatures
onthese regions, which occurs due to compositional variation
in those regions. The martensite phase fraction inthe
thermally affected regions may have significant implications
on functional properties on these joints.},
