  • Structural Materials


Improvements in the reliability of fabricated materials require a better understanding of the physics and the chemistry of the processes that are used. Although most of Prof. Eagar's research involves welding and joining, an increasing amount of work involves other aspects of materials manufacturing and engineering systems.

Examples of recent research include:

Fundamentals of transient liquid phase diffusion bonding as applied to composites, superalloys and electronic packaging
Control of melting during gas metal arc welding

Effects of welding fume on health of workers

Stresses generated during joining of dissimilar materials

Improved methods of dimensional analysis of materials processing

Design, forming and assembly of automotive body components

Methods for successful product design and development

There are two MacArthur “Genius Grant” recipients on the DMSE faculty.
