Abstract Scope |
Pores are present in additively manufactured metals made using methods ranging from laser powder bed fusion (L-PBF) to binder jetting. The impact of these pores on the load-bearing capacity, or failure behavior, of components made by additive manufacturing (AM) must be understood for wider-scale adoption of AM for structural components. This talk will present methods for introducing pores into additively manufactured parts, and characterizing these pores, in order to study their impact on failure behavior of additively manufactured stainless steel 316 (made by binder jet AM and L-PBF) and Ti-6Al-4V (made by L-PBF). Additionally, as AM is ideally suited for the fabrication of complex geometries, different locations within components will be subjected to different stress states (e.g., shear, biaxial tension); thus, the measured and modeled combined effect of stress state and pores on the failure behavior of these alloys will be discussed. |
