dc.description.abstract |
The effects of pulsed gas tungsten arc weldingparameters on the morphology of
additive layer manufacturedTi6Al4V has been investigated in this study. Thepeak/
base current ratio and pulse frequency are found tohave no significant effect on
the refinement of prior betagrain size. However, it is found that the wire feed
ratehas a considerable effect on the prior beta grainrefinement at a given heat
input. This is due to the extrawire input being able to supply many
heterogeneousnucleation sites and also results in a negative temperaturegradient
in the front of the liquidus which blocks thecolumnar growth and changes the
columnar growth toequiaixal growth. |
