Numerical exploration of the spiral state in the pattern formation of the Swift-Hohenberg equation on a sphere

Gotoh Fumitoshi , Generalis Sotos C. , Itano Tomoaki

… Tracing the state by a continuation method generated from the static state via three symmetry breakings, the spiral state may be regarded as a resonant state generated by the combination of a few degenerate unstable modes with different azimuthal wave numbers.This work has been supported in part by KAKENHI (20K04294). …

Effect of Carbon Concentration in Austenite on Cementite Morphology in Pearlite

Yasuda Tadao , Nakada Nobuo

… To understand the formation mechanism of degenerate pearlite, the effect of carbon concentration on the cementite morphology in pearlite was investigated in hypoeutectoid C–Mn steels with fully pearlite and ferrite–pearlite duplex microstructures. … The ferrite growth rate increases with decreasing carbon concentration in austenite, which leads to non-cooperative growth between ferrite and cementite in the eutectoid reaction, resulting in the formation of degenerate pearlite. …
