一、微合金元素和微合金化钢 目前,微合金元素的定义因人而异,有的认为,微合金元素不仅包括钒、铌、钛、铝、锆,还包括硼、磷、碲(Te)等元素;有的认为,虽然铝、硼、氮对钢的性能有重要影响,但不叫做微合金元素,只有钒、铌、钛叫做微合金元素;有的把微合金元素分为老一代与新一代,前者为钒、铌、钛,后者为钙、锆、稀土。由此可见,虽然在微合金元素的数量上有分歧,但钒、铌、钛是公认的微合金元素。
Microalloying elements and microalloyed steels Currently, the definition of microalloying elements varies from person to person. Some people think that microalloying elements include not only vanadium, niobium, titanium, aluminum and zirconium, but also boron, phosphorus and tellurium (Te ) And other elements; some believe that although aluminum, boron, nitrogen has a significant impact on the performance of steel, but not called microalloying elements, only vanadium, niobium, titanium is called microalloying elements; some microalloy elements into the older generation And the new generation, the former is vanadium, niobium, titanium, the latter is calcium, zirconium, rare earth. Thus, although there are differences in the number of microalloying elements, vanadium, niobium and titanium are well-recognized microalloying elements.
