Beautiful physics governs complex energy-matter interactions


The analysis team, led by Tao Sun, an associate professor of supply science and engineering at the University of Virginia, has made two discoveries that can expand additive manufacturing in the aerospace industry and various industries that depend on solid metal elements.

As stated by the Association for Production Technology, additive production has been contributing to the production of aircraft for years. Moreover, the production of additives generates errors in the microstructure of the completed half, which limits its function to the production of pipes, internal parts and various non-critical elements. Additive production of safety-regulated elements will help the company achieve its ambitions to provide chain management ecologically and steadily, in addition to financial gas savings and emission reductions that accompany lighter aircraft.

Sun employees and colleagues have discovered why structural defects occur in the additive manufacturing of elements made from the high-strength, lightweight titanium alloy widely used in aerospace work. They represent the current course of the map – the scheme that machines use to create the element – ​​that helps manufacturers avoid manufacturing errors in a specific additive manufacturing approach known as laser powder mattress fusion.
