Compositional Optimisation of a Ni-based Superalloy for Additive Repair Applications
… for this system. In this thesis, the laser-blown-powder directed-energy-deposition (LBP-DED) of IN718 is characterised and novel methods for compositionally optimising the deposition of this system are investigated. It is shown that a Brass texture ({110} <211>) can be obtained in LBP-DED …

An Investigation of Polymer Support Structures In Metal Directed Energy Deposition
… the viability of polymers as supports in laser blown-powder DED, providing guidelines for polymer selection and print strategy to avoid detrimental polymer degradation, unsafe combustion conditions, and negative impacts of using a dissimilar substrate on the deposited metal DED component. An …

Build strategy investigation of TI-6AL-4V produced via a hybrid additive manufacturing process
“Till now, laser metal deposition (LMD) has been developed with the capability of near-net shape high-performance metal parts fabrication, especially complicated titanium alloys, nickel alloys, and aluminum alloys. However, LMD processed parts usually do not meet end-use requirements without post …
