【Abstract】 By through the statistics of the test results with Cu,Mo and Sb,the segregation character-istics,the capacity to form carbides and strengthening mechanism of alloying elements was analyzed.It was proposed to use trace amount of multi-elements for strengthening to produce as -cast hi-strength and hi-toughness nodular iron,and a ideal result has been obtained in the trial production.更多还原
