Etymology: < polygon n. + -ization suffix. Compare later polygonize v.

1. Materials Science and Physical Geography. The formation of smaller grains within the grains of a metal as a result of the migration of dislocations following deformation and subsequent annealing; a similar phenomenon in other crystalline materials, such as rock and ice. Also: the arrangement of subgrains following such a process.

1948 R. W. Cahn in Rep. Conf. Strength Solids 1947 (Physical Soc.) 137 The x-ray and microscopical results together lead to an interpretation as follows: the deformation leads to elastic bending of glide lamellae; when the crystal is annealed, the lamellae undergo ‘polygonization’.

1949 R. W. Cahn in Jrnl. Inst. Metals 76 136 It is suggested that the process be named polygonization, to distinguish it from other forms of recrystallization.
