WebApr 12, 2024 · Here, the anisotropy decreases with the temperature increment across VT, as the crystalline structure changes from monoclinic to cubic spinel, which can be observed in both samples [74,75,76]. The higher change in H C was observed in the 5 h annealed sample because when the volume fraction of Fe 3 O 4 is higher, it leads to a larger … WebJan 30, 2024 · Crystalline polymers have large amorphous areas, which is why we call them semi-crystalline polymers. Semi-crystallines also have sharp melt points. While amorphous materials soften gradually when the temperature rises, semi-crystalline plastics do not. Instead, they remain solid until a certain quantity of heat is absorbed.
