| Abstract: | Micro-alloying function of Ti, Nb- Ti ,V-Ti, Mn-Ti and Mo-Ti was introduced, and key points of Ti micro-alloying technology was suggested by analyzing precipitation thermodynamic and comparing difference of Ti precipitation between traditional casting and rolling and thin slab casting and rolling process. The key points include elements design, smelting technology and controlled rolling and cooling technology. The analysis for Ti micro-alloying will play an important role in industrial application and technology development. |
