钛是极为活泼的元素,与氮、碳都有极强的亲和力,和氧及硫的亲和力也大于铁。从微合金化钢中常用的合金元素来看,钛与碳、氮、氧、硫之间的亲和力均大于钒和铌,与氧和硫的亲和力虽不及稀土,但与碳和氮的亲和力却大于稀土。由此便 Titanium is a very lively element, with nitrogen, carbon has a very strong affinity, and oxygen and sulfur affinity is also greater than iron. From the alloying elements commonly used in microalloyed steel point of view, the affinity between titanium and carbon, nitrogen, oxygen and sulfur are greater than vanadium and niobium, with oxygen and sulfur though less than rare earth affinity, but with carbon and nitrogen affinity Greater than rare earth. From this
