- Title
The Mechanical Behavior of Multiphase Nanocrystalline Materials.

- Abstract
Most commercial structural materials are multiphase and it is expected that multiphase nanocrystalline materials will also eventually be the materials of choice for applications. There has been limited research so far on the influence of second-phase particles in a nanostructured matrix. More studies have been carried out on nanoscale second phases in an amorphous matrix. This paper will review the examples from the literature of mechanical properties in nanocystalline materials as influenced by second-phase particles. Work from the authors' laboratory on nanoscale particles in nanocrystalline aluminum and iron will be emphasized. These particles include both "hard" and "soft" phases and exhibit a wide range of hardness behavior. Mechanisms for the observed effects will be suggested.
