dc.description.abstract It is difficult to produce titanium aluminides (TiAl) components because these materials lack ductility and when used as high temperature structures they fail prematurely due to the inability to self-oxidise. In this study, a 20 by 20 mm cube part was deposited on Ti64 substrate from elemental Ti and Al using LENS and laser power of about 400 W. The microstructural evolution across the sample concluded a lamella rich structure was produced. The EDS concluded an Al:Ti ratio of 1:4 which could mean that Ti3Al and TiAl were the resulting phases. Vickers’s average hardness value of 290 HV0.3 was reported. This HV value corresponds to the Ti3Al and TiAl phases. en_US
