Micrograph showing precipitates growing larger and changing shape

Description:

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., http://www.sciencedirect.com. Used with permission.)
