Abstract:
Additive manufacturing is an opportunity for the energy field to produce sophisticated geometries. However, there are still several roadblocks to its use to make a wide variety of parts. One needs to demonstrate that parts produced with conventional processing routes can be substituted by parts fabricated by additive manufacturing. Parts made of 316L stainless steels have been fabricated using two different powder batches while keeping the exact same processing conditions. The nominal composition of the two initial powder batches differs slightly, but it led to very different microstructures. Powder batch 2 leads to a finer grain structure that goes along with texture randomization. The underlying mechanism responsible for grain refinement and texture randomization is discussed and can be considered as an alloy design strategy in the framework of additive manufacturing.
