About
Dr. Zhiwei Lyu is a materials scientist specializing in additive manufacturing, with a particular focus on the microstructure and mechanical behavior of metallic components. His research centers on wire arc additive manufacturing (WAAM), a technique for building large-scale metal parts layer by layer. Dr. Lyu’s major contribution lies in elucidating how the complex thermal history inherent in WAAM creates distinct microstructural distributions along a build, and how these variations directly control anisotropic mechanical properties. In his highly cited 2021 study on a 2Cr13 martensitic stainless steel thin wall, he demonstrated that vertical specimens from the lower part of the wall exhibit lower strength but higher elongation, a finding critical for predicting and designing the performance of additively manufactured parts. This work, which has garnered 11 citations, provides essential guidance for engineers seeking to optimize WAAM processes for structural applications. By connecting microscale features to macroscale tensile behavior, Dr. Lyu’s research is helping to advance the reliability and industrial adoption of wire arc additive manufacturing for high-performance steel components.
