硫在Ti-IF钢中的作用

Action of Sulphur in Ti-IF Steel

    摘要
  • 摘要: 作为IF钢成分设计的基本思想是将钢中间隙固溶的C,N原子完全清除.但通过热力学分析和对析出物的TEM分析表明,由于碳硫析出物的存在,S在固定C原子方面起到了积极的作用.据此,保持钢中适度的S/C比,可充分发挥S的作用,以形成有利的固定C的产物.

     

    Abstract: The composition design idea of IF steel is eliminating the atoms of C and N dissolved in steels. On the basis of the thermodynamics analysis and the TEM observation of extraction precipitates, it is shown that sulphur can act as a positive role to fix the interstitial carbon atoms due to the exist of Ti4C2S2. If a proper ratio of sulphur and carbon in Ti-added IF steel is kept, the favorable precipitate will be product.
