用电子背散射衍射/威尔金森法显示了珠光体组织中的弹性应变及其分布。发现珠光体团具有不同类型的应变场。讨论了弹性应变产生的几种机制，认为弹性应变的产生主要是由于珠光体转变温度下铁素体与铁素体之间的晶格失配所致。
Elastic strain and its distribution in a pearlite structure were visualized by means of the electron backscatter diffraction/Wilkinson method. It was found that pearlite colonies have different types of strain fields. Several mechanisms for elastic strain generation were discussed, and it was concluded that the elastic strain is mainly generated because of the lattice misfit between ferrite and cementite at the temperature at which pearlite transformation takes place.
