摘　　要：钢中珠光体转变属典型的扩散型共析转变。其典型的显微组织为层片状珠光体。本文吸取了国内外近一二十年中关于珠光体转变的主要研究成果,阐述了珠光体形成热力学、动力学、形成机制、影响因素和产物的力学性能等。最后讲述了珠光体生长的台阶机制及一些非铁碳合金的共析组织。Pearlitic transformation in steel is a typical diffusion eutectoid transition.Its typic microstructure calls lamellar pearlite.In this paper we express the thermodynamics,kinetics,forming mechanism,effect factors of forming of pearlite and mechanical properties of transformation products associated with the main research results in recent twenty years at home and abroad.At the last,the steps mechanism of pearlitic growing and some eutectoid structures of non Fe-C alloys are pointed out.
