摘要
Abstract
Dilatometric tests were performed on the dilatometer under different cooling rates for the steels and the microstructures were observed. The point analysis of main elements was analyzed with the EMPA. The elements of Mo and Si were important for controlling grain transformation of the pearlite and granular bainite. When cooling rate at≤0.015℃/s, the variation of the microstructures was more complicated. The pearlite could be observed in the cooling slowly, the elements were heterogeneous distribution. The bainites were not the single microstructures, the morphology of bainites were lamellar and disordered granular. The pearlites presented at disordered granular area mainly.关键词
