摘要
提出相变研究的展望,如无能垒形核的理论与实验。由于材料形态和性质紧密相关,初步建议重视发展《材料形态学》。对共析钢中珠光体相变的过冷度或相变温度和珠光体片间距之间的关系以及珠光体形态(片间距)影响珠光体强度的文献作了总结。本文提出了一个过冷度和珠光体强度间关系的定量表达式。
Perspective in phase transformation studies, such as theory and experiment of barrier-free nucleation is discussed. Since morphology is closely related to the properties of materials, a brief suggestion on the development of 〈Materials Morphology 〉 or 〈 Study of Morphology in Materials 〉 is emphasized. Works on relationships between the undercooling or transformation temperature and interlamellar spacing of pearlite and the effect of morphology (interlamellar spacing ) on the strength of pearlite in eutectoid steel are reviewed. This article gives quantitative description of the relationship of the undercooling to the strength of pearlite.
