While turbostratic graphite is documented in many forms of graphite, there is a paucity of information on its contribution to the crystallization of spheroidal graphite (SG) in cast iron. SAD on SG and discussion of deep-etched SEM samples, demonstrates that it is an integral part of the crystallization sequence of SG. It is found in the core region, but also in the outer shell. This imposes a reevaluation of current theories of SG crystallization.

湍层石墨在球状石墨液-固转变过程中结晶过程中的作用

虽然乱层石墨以多种形式存在，但有关其对铸铁中球状石墨 (SG) 结晶的贡献的信息却很少。对 SG 的 SAD 以及对深蚀刻 SEM 样品的讨论表明，它是 SG 结晶序列的一个组成部分。它存在于核心区域，但也存在于外壳中。这迫使我们重新评估当前的 SG 结晶理论。
