| Abstract Scope |
Any variation in the processing parameters of selective laser melting fabrication could impact the performance of the final product. In this study, the effects of laser power, scanning speed and hatch spacing on the NiTi shape memory alloys were evaluated and related to the linear and total energy densities. Multiple Ni50.8Ti49.2 samples were systematically fabricated with selected laser power from 50 to 250 W and their microstructure, transformation temperatures, texture, and shape memory response were investigated. It was demonstrated that only using the energy levels cannot explain the trends observed. |
