Metrology Needs for Metal Additive Manufacturing Powders

Autor: Edward J. Garboczi, John A. Slotwinski

Publikováno v: JOM. 67:538-543

Additive manufacturing (AM) processes can produce highly complex and customized parts without the need for dedicated tooling and can produce parts directly from the part design information. These types of processes are poised to revolutionize the man

Investigation of pore structure in cobalt chrome additively manufactured parts using X-ray computed tomography and three-dimensional image analysis()

Autor: Felix H. Kim, Shawn P. Moylan, Edward J. Garboczi, John A. Slotwinski

Pore structures of additively manufactured metal parts were investigated with X-ray Computed Tomography (XCT). Disks made of a cobalt-chrome alloy were produced using laser-based powder bed fusion (PBF) processes. The additive manufacturing processin

Mechanical Properties of Austenitic Stainless Steel Made by Additive Manufacturing

Autor: John A. Slotwinski, William E. Luecke

Publikováno v: Journal of Research of the National Institute of Standards and Technology

Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials,
