| Abstract Scope |
Additive manufacturing (AM) has the capability to revolutionize the way shape memory metals are used due to the unique ability to create complex geometry and modify microstructure with laser parameters spatially. This work has been focused on solving the fundamental research challenges associated with designing and additively manufacturing functional, stimulus-responsive components from NiTi shape memory alloys via selective laser melting (SLM). A ground up approach was used starting a single track analysis and working through a full parameter set to produce dense nitinol components. Substrate interactions were analyzed to establish conditions that produce correct stoichiometry even on highly mismatched substrate chemistry. The ability to produce large complex geometry shape memory components on Ti64 substrates will be discussed. In addition the ability to tune processing parameters to impact the overall shape memory response will be discussed to achieve a tailorable actuation in a complex geometry. |
