首次提出“球晶热力学不稳定区”的概念,论证了球化处理的热力学贡献;将结晶学的界面稳定性理论用于解释球状石墨的生长过程,提出石墨球“界面动力学稳定性”的概念,分析了球化处理的动力学贡献;并从界面生长理论出发,论证了石墨球生长的晶格位向条件。 The concept of “spherulites thermodynamically unstable zone” was first proposed and the thermodynamic contribution of spheroidizing treatment was demonstrated. The theory of interface stability of crystallography was used to explain the growth process of spherulitic graphite, and the “kinetic stability of interface” Concept, the dynamic contribution of spheroidization was analyzed. Based on the interface growth theory, the lattice orientation of the graphite spheres was demonstrated.
