Abstract—

We have experimentally demonstrated continuity of hypoeutectoid and pearlite ferrites in aggregates in the microstructure of low-carbon, low-alloy ferrite–pearlite steel. Such ferrite aggregates of various origins have been repeatedly observed along with hypoeutectoid ferrite and pearlite grains. We propose that aggregates of hypoeutectoid and pearlite ferrites should be regarded as a characteristic microstructural feature and this should be taken into account in microstructural characterization.

低碳，低合金钢中的次共析和珠光体铁素体聚集体

摘要-

我们已经通过实验证明了低碳低合金铁素体-珠光体钢的组织中次共析和珠光体铁素体的连续性。已经多次观察到这种不同来源的铁素体聚集体以及亚共析铁素体和珠光体晶粒。我们建议将次共析和珠光体铁素体的聚集体视为特征性的微结构特征，并且在微结构表征中应考虑到这一点。
