INVESTIGATION OF THE EFFECT OF ALLOYING ELEMENTS ON SHEAR BAND FORMATION DURING THE WARM ROLLING OF LOW CARBON AND INTERSTITIAL FREE STEELS. This proposal involves the application of three dimensional atom probe field ion microscopy and advanced transmission electron microscopy techniques to study the phenomena of precipitation and solute atoms' interactions with dislocations in warm rolled low carbon steels and interstitial free steels. It is intended to examine the effect of alloying additions on in-grain shear bands formation, texture formation and formability of warm rolled and annealed low carbon steels. Ultimately, the project is concerned with developing of fundamental understanging of solute interactions which provide an improved basis for design of these economically significant steels.

低碳无间隙钢温轧过程中合金元素对剪切带形成影响的研究。应用三维原子探针场离子显微镜和先进的电子显微镜技术研究了温轧低碳钢和无间隙位错钢中的析出和溶质原子与位错的相互作用现象。研究了合金元素对温轧低碳钢和退火态低碳钢晶内剪切带形成、织构形成和成形性的影响。最终，该项目致力于发展对溶质相互作用的基本了解，为这些具有重要经济意义的钢材的设计提供更好的基础。
