Dr. Tang specializes in mechanical metallurgy and metal additive manufacturing, with an emphasis on defect characterization, root cause analysis, and life prediction. He has 10-years research experience in metals, including aluminum, iron & steel, titanium, and nickel. He has expertise in the application of microscopy (automated SEM) techniques in various areas, particularly quantifying defects (pores and non-metallic inclusions) for a broad range of metallic materials and examining their effect on mechanical performance. While working at Carnegie Mellon University, Dr. Tang focuses on the aluminum-silicon alloy parts produced by additive manufacturing (specifically, selective laser melting), including defect characterization (by 2D SEM and 3D CT), microstructure control, and fatigue life prediction.
