3D Printing One of the Strongest Stainless Steels

Department of Energy, Office of Science — Thu, 10 Oct 2024 14:05:48 EST

Researchers have developed a way to consistently produce 17-4 PH stainless steel using additive manufacturing, or 3D printing. The rapid change in temperatures that occur in these materials after they are heated by the lasers in 3D printers make it difficult to achieve the toughness needed for 17-4 PH steel. This research used bright X-ray beams to observe those fast changes in real time, then altered the chemical composition to compensate for them.
