Micrographs show precipitates growing larger and changing shape.

Precipitates in Ni-Al under elastic stress evolve in size and shape over time, developing from randomly aligned spheres into plates and rods aligned with the stress axis. This microstructure resists creep even at high temperatures. (Courtesy of Elsevier, Inc., Used with permission.)

Course Description

The central point of this course is to provide a physical basis that links the structure of materials with their properties, focusing primarily on metals. With this understanding in hand, the concepts of alloy design and microstructural engineering are also discussed, linking processing and thermodynamics to the structure and properties of metals.
