Hybrid manufacturing involves both additive and subtractive (machining) processes to achieve the final product. Substantial differences can exist between the mechanical behavior of additively as-built materials compared to their wrought counterparts. As such, the use of wrought material properties for the simulation and optimization of the machining step in a hybrid manufacturing process may produce inaccurate results. The present work uses the NIST pulse-heated compression Kolsky bar to measure the dynamic behavior of both wrought and additively produced Inconel 625 and 17-4 PH stainless steel over a range of temperatures up to 1000 °C and at strain rates of 3000 s −1 . The measurement results are correlated to underlying microstructural differences between additive and wrought materials that arise because of the differences between these material processing routes as described in the literature.
