Microstructural and Hardness Behavior of H13 Tool Steel Manufactured by Ultrasound-Assisted Laser-Directed Energy Deposition

Metal additive manufacturing (AM) by Laser-Directed Energy Deposition (L-DED) usually results in the formation of textured columnar grains along the build direction, leading to anisotropic mechanical properties. This can negatively affect the intended application of the product. Anisotropy can be eliminated by modifying the material through an...

Printing a stainless steel bridge: An exploration of structural properties of stainless steel additive manufactures for civil engineering purposes

The potential of additive manufacturing is great: highly complex and efficient structures can be manufactured with hardly any waste material. While high-tech industries such as aviation and medicine have already embraced additive manufacturing, civil engineering is lagging behind. Research on the structural properties of additive manufactures in...
