Scientists from Texas A&M University and the U.S. Air Force say they’ve developed a way to 3D print the strongest kind of steel, along with many other metals.By using a steel powder melted into place by a laser, this process follows in the footsteps of technologies like powder welding. And by adding a mathematical model to gauge which laser settings will best reduce printing flaws, the researchers have made a process they say makes strong steel into strong 3D-printed steel items.The mathematical model and its results are presented as an “optimization framework” that anchors the research team’s new paper.“This framework utilizes the computationally inexpensive Eagar-Tsai model, calibrated with single track experiments, to predict the melt pool geometry,” the team writes. “Computationall...

A team of the TSU Laboratory of High-Strength Crystal Physics is creating highly entropic alloys that differ in the unusual structure of the crystal lattice. They provide new materials with mechanical characteristics that make them suitable for use in the extreme conditions of space and the Arctic – at high and low temperatures, under load, and when exposed to radiation.
