The microstructure of a material controls its mechanical properties and other physical properties (Chapter 3). Microstructural parameters that have a major influence on mechanical properties are

 Porosity, the volume fraction of pores in the material, as well as their distribution within the material and their shape

 Grain size, relevant to metals and ceramics

 Presence of microstructural flaws such as microcracks and pores, often introduced accidentally during fabrication of the material, particularly relevant to brittle materials.
