Abstract

A great amount of variance exists in the properties of any material. The ability to accurately predict these properties allows for designers to find the “best” material in highly constrained design situations. Many properties, such as elasticity and conductivity, are relatively insensitive to grain boundary interfaces and dislocations, and are thus accurately predicted by simple averaging techniques with a first-order description of the microstructure. However, many properties that effect lifetime to failure such as plastic yielding, intergranular stress corrosion cracking, and embrittlement are sensitive to dislocations and grain boundary interfaces. Therefore, second-order descriptions of the microstructures are needed to estimate these properties. It is not just what is in the material, but how it is arranged that is needed.
