| 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 can display a vast spread in mechanical behavior as attributed to the microstructure of the material after processing. A case study of 304L and 316L stainless steel produced through laser powder bed fusion (LPBF) was conducted to evaluate whether the unique microstructure and plasticity can be represented by constitutive parameters for materials as determined from work hardening behavior. TEM work was conducted at different stages of work hardening to help correlate microstructure to macroscopic deformation 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. |
