Creation of Dissimilar Materials Structures

Monday, October 25 | 1:30 PM - 2:30 PM

Stephen F. & Camilla T. Brauer Hall, 12
6548 Forest Park Pkwy, St. Louis, MO 63112, USA

Jingjing Li, Associate Professor, Industrial and Manufacturing Engineering  Pennsylvania State University.  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.
