A systematics of grain boundary (GB) segregation transitions and criticalphenomena has been derived to expand the classical GB segregation theory. Usingtwist GBs as an example, this study uncovers when GB layering vs. prewettingtransitions should occur and how they are related to one another. Moreover, anovel descriptor, normalized segregation strength (phi_seg), is introduced. Itcan represent several factors that control GB segregation, including strain andbond energies, as well as misorientation for small-angle GBs (in a mean-fieldapproximation), which had to be treated separately in prior models. In a strongsegregation system with a large phi_seg, first-order layering transitions occurat low temperatures and become continuous above GB roughing temperatures. Withreducing phi_seg, the layering transitions gradually merge and finally lumpinto prewetting transitions without quantized layer numbers, akin to Cahn'scritical-point wetting model. Furthermore, GB complexion diagrams withuniversal characters are constructed as the GB counterpart to the classicalexemplar of Pelton-Thompson regular-solution binary bulk phase diagrams.
