Titanium aluminides (TiAl) are interesting intermetallic materials to study due to their enhanced high temperature and light weight properties. They are necessary as structural materials, but brittle to form with conventional methods. Hence big corporates are interested in developments that will lead to cost effective manufacturing technologies that are able to produce homogenous, defect free TiAl structures. Additive manufacturing is one promising technology hence it was explored here in studying process development of producing TNB alloy using laser in-situ alloying approach. The produced alloy, -TNB, appeared to be homogeneous after heat-treatment and had hardness of 576HV.
