In this work, CoCrNi medium-entropy alloy (MEA) parts were fabricated by laser powder bed fusion (LPBF) with different powers. The microstructural evolution before and after tensile test was characterized to explore the strengthening ductility improvement mechanisms. Similar microstructures performances achieved among samples that processing parameters, which indicates a credible parameter window for fabricating high-quality samples. An excellent combination of strength acquired (yielding strength: 689–700 MPa, ultimate 963–973 elongation fracture: 31.9–37.7%), primarily attributed grain boundary mechanism adequate working hardening capacity, respectively. After test, most grains rotated aligning 〈1 1 0〉 directions, along high-density low angle boundaries. Besides, both deformation twinning dislocation multiplication activated during process, acted as dominant findings above reveal LPBF can fabricate MEAs cellular columnar sub-structures, an without sacrificing ductility.

Multi-material structure fabrication has the potential to address some critical challenges in today’s industrial paradigm. While conventional manufacturing processes cannot deliver multi-material structures a single operation, additive (AM) come up as an appealing alternative. In particular, laser-directed energy deposition (L-DED) is preferred for AM. The most relevant applications envisioned L-DED are alloy design, metal matrix composites (MMC), and functionally graded materials (FGM). Nonetheless, there still issues that need be faced before ready use. Driven by this need, literature review, suitability of component first demonstrated. Then, main defects associated with current opportunities field reported. view relevance high-performance coatings tools mitigate wear, emphasis placed on development MMCs FGMs. identified include—but not limited to—tightly controlling composition powder mixture injected into melt pool; understanding influence thermal history process microstructural aspects, including interactions between constituents; studying in-service behaviours FGMs regard their durability failure modes.
