Abstract Scope |
Additive manufacturing (AM) is a key technology that is reshaping the production of metal parts, allowing for reduction of waste, faster lead times, complex geometries, and rapid prototyping. With the wide array of processing methods and parameters, AM materials display a vast spread in mechanical behavior caused by the unique microstructural state of the material after processing. A case study of 304L and 316L stainless steel produced through laser powder bed fusion (LPBF) was conducted in order to test whether the unique microstructure and plasticity – characterized by differences in composition, build direction, and porosity – can be represented by a single constitutive parameter for materials which follow typical Kocks-Mecking work hardening behavior. The establishment of a repeatable procedure for implementation and critically validating the model through various case studies will be paramount for creating an effective tool for predicting and leveraging the variable properties exhibited by metal AM components. |
