Researchers Devise Way to Print Better Martensitic Steel Parts
04/20/2020 - Researchers from Texas A&M University and the U.S. Air Force Research Laboratory have developed an optimized process framework that allows for defect-free 3D printing of components from martensitic steels.
"Strong and tough steels have tremendous applications but the strongest ones are usually expensive—the one exception being martensitic steels that are relatively inexpensive, costing less than a dollar per pound," said Dr. Ibrahim Karaman, head of the university’s Department of Materials Science and Engineering. "We have developed a framework so that 3D printing of these hard steels is possible into any desired geometry and the final object will be virtually defect-free."
Their work appears in Acta Materialia.
