Abstract Scope |
Fusion-based additive manufacturing technologies enable the fabrication of geometrically and compositionally complex parts unachievable by conventional manufacturing methods. However, the phase transformation behavior of materials under non-uniform and far-from-equilibrium heating/cooling conditions is not fully understood, which is a major barrier for rational design of materials and processing conditions to consistently obtain desirable phases in the as-printed parts. In this talk, I will present the key data and insights my research group obtained on uncovering phase transformation dynamics under additive manufacturing conditions by using high-speed high-energy synchrotron X-ray diffraction. |
