Applications of quantitative microscopy in materials engineering

Among the examples reviewed are volume‐fraction measurements in phase diagram and kinetic studies, properties dependent upon internal surface area, the characterization of phase arrangements by contiguity, proximity and dihedral‐angle measurements. The use of grain boundary and particle spacings in studies of mechanical properties is discussed in relation to current theories of strengthening mechanisms. Applications of size‐distribution analysis in kinetic studies and in the assessment of inclusion contents in steels are surveyed.
