Abstract

The rapid and free forming characteristics of laser melting deposition (LMD) bring new design ideas andmanufacturing methods for the development of aeronautical components. In this paper

the microstructure and mechanical properties of laser melting deposited (LMDed) titanium alloys and titanium matrix composites (TMCs) are summarized and analyzed

including the effects of deposition parameters

heat treatment and the types and content of reinforcements on the microstructure and mechanical properties of LMDed components. It is found that the deposition parameters directly affect powder melting

the fusion quality and the microstructure of components after deposition

which influences the microstructure and properties of deposited components. By appropriate heat treatment

the forming stress could be reduced and the microstructure and properties of components can be modified. The reinforcement content is closely related to its solubility in the matrix

which makes TMCs show different microstructures and mechanical properties compared to titanium alloys. Finally

the application of LMD technology in the manufacture and repair of titanium alloy and TMCs components are analyzed and concluded.
