| Abstract Scope |
Titanium/titanium carbide mixtures with the TiC contents of 20, 40 and 60vol.% were successfully deposited onto Ti64 substrates by Laser Engineered Net Shaping process. The process produced a well-bonded and continuous interface between the coating and substrate. From cross-sectional microstructural examination, the coatings comprise three different morphologies of TiC phase embedded in Ti matrix: angular particles from feed mixture, dendritic and equiaxed particles from the solidification of melt pool. The compositional differences in different carbide particles have been identified using the XRD and EPMA techniques. The heat affected zone in Ti64 substrate, near the interface, showed needle-shaped features that suggests martensitic transformation of the parent phase. Here, the correlation of mechanical properties of coatings and volume fraction of different resolidified TiC particles with TiC volume fraction will be discussed. A possible means towards the prediction of mechanical properties in a printed material using machine learning methods will be described. |
