Microstructure prediction and solidification modelling in LPBF
Xianglong Wang works on the link between melt-pool dynamics and solidification microstructure in laser powder bed fusion. His doctoral and postdoctoral work — at Penn State and the University of Auckland — combined finite-element thermal-fluid simulation with cellular-automaton and phase-field models to predict columnar versus equiaxed grain structure, texture, and segregation in LPBF nickel and titanium alloys. He has published on the microstructure of LPBF Inconel 718, Ti-6Al-4V, and tool steels, and on the use of process maps to navigate the columnar-to-equiaxed transition. His work is most often associated with the broader Penn State and Auckland metal AM groups led by DebRoy and Stucker.
