What is Synthesis and Characterization of Innovative Fe–Cr–Mn Ferritic Stainless Steel by Laser Powder Bed Fusion about?
Crack development for laser-fused metallic materials is one major challenge for laser-based powder bed fusion (LPBF). The cracks are manifested in two forms, i.e., macro-cracks along building layers due to spalling and micro-cracks along the high-angle grain boundaries. To mitigate the crack formation, a new type of ferritic stainless steel Fe-Cr-Mn has been synthesized by LPBF. The well-developed columnar ferrite grains with an enhanced fine acicular austenite precipitation, which possess Nishiyama-Wassermann (N-W) orientation relationship with the ferrite matrix, can be readily produced when the laser energy density is beyond 100 J/mm 3 . Porosity can be further reduced below 0.5% by optimizing the laser power and scanning speed. It has been found that laser rescanning may eliminate the cracks without modifying the grain morphology, crystallographic texture, and phase distribution.
