MURI Objectives: To determine how the atomic structure of grain-boundary interphases—interphase complexions—affect the mechanical, electrical and thermal properties of a wide range of strategic engineering materials.

“This new funding will allow us to extend our studies to determine the role that interphase complexions play in the properties of a wide range of materials such as nickel alloys and tungsten carbide—cobalt composites whose properties are well known,” M. Harmer (PI) says.
