Abstract: The effect of niobium on microstructure and mechanical properties of Nb-contening cast irons, including gray cast iron, undercooled cast iron, and nodular cast iron were discussed in this paper. Besides, the application of Nb-contening cast irons was also proposed and expected in the future.

Keywords: niobium; chilled cast iron; nodular cast iron; mechanical properties; microstructure; grey cast iron; undercooled cast iron.
