Title Effiect of silicon and prior deformation of austenite on isothermal transformation in low carbon steels Author(s) Cai, Minghui Ding, Hua Zhang, Jiansu Li, Long Journal name Acta metallurgica sinica (English letters) Volume number 22 Issue number 2 Start page 100 End page 109 Total pages 10 Publisher Acta metallurgica sinica (English letters) Place of publication Shenyang, China Publication date 2009-04 ISSN 1006-7191 Keyword(s) bainite transformation, ferrite transformation low carbon steel prior deformation of austenite Si content Summary Isothermal transformation (TTT) behavior of the low carbon steels with two Si contents (0.50 wt pct and 1.35 wt pct) was investigated with and without the prior deformation. The results show that Si and the prior deformation of the austenite have significant effiects on the transformation of the ferrite and bainite. The addition of Si refines the ferrite grains, accelerates the polygonal ferrite transformation and the formation of M/A constituents, leading to the improvement of the strength. The ferrite grains formed under the prior deformation of the austenite become more homogeneous and refined. However, the influence of deformation on the tensile strength of both steels is dependent on the isothermal temperatures. Thermodynamic calculation indicates that Si and prior deformation reduce the incubation time of both ferrite and bainite transformation, but the effiect is weakened by the decrease of the isothermal temperatures.
