Currently, knowledge on the performance of many additively manufactured (AM) materials is lacking. One way to address this issue is to develop models that link the process, structure, and properties of AM materials. Developing models is a challenge because the structure of AM parts varies on two separate length-scales from traditional manufacturing methods. The problem that will be addressed directly is that the mechanical properties of stainless steel micro-tensile specimens are very different, although they were produced by an identical AM process.
This project will study the structure on the meso length scale, where the surface roughness, pores, and matrix can be distinguished as separate phases. However, this method does not account for variation in the microstructure of the matrix. The fundamental questions being addressed by this project are:
1. What is the mesostructural variation between AM microtensile specimens?
2. How does the mesostructural variation impact performance/macroscale properties of the specimens?
