Professor, Harold and Inge Marcus Department of Industrial and Manufacturing Engineering, Pennsylvania State University

Abstract

Increasing environmental concerns and demands for high-performance products drive the needs for manufacturing dissimilar materials structures with tailored properties. However, fabricating these structures by conventional fusion welding is challenging. The generation of brittle phases (i.e., intermetallic compounds) is a significant concern and could negatively impact weld integrity, strength, and reliability. This talk will review Dr. Li’s recent work on creating dissimilar materials structures through additive manufacturing and different welding methods. In particular, she will focus on interfacial bonding mechanisms, defect generation, and the development of process-structure-property relations. She will also introduce new material characterization techniques developed by her group.

Speaker Bio

Jingjing Li is a Professor of the Harold and Inge Marcus Department of Industrial and Manufacturing Engineering at the Pennsylvania State University, University Park. She earned a PhD in mechanical engineering and MA in statistics from the University of Michigan, Ann Arbor, USA, an MS from Tsinghua University and a BS from Beihang University, Beijing, China, both in materials science and engineering. Her research is driven by a deep passion for materials processing and characterization, with a particular emphasis on in-situ materials analysis, mechanical behavior, failure mechanisms, and the influence of microstructure on macroscopic properties.
