【Abstract】 Micro-alloying elements(Al,Nb,V) have been investigated experimentally on the precipitate behavior and strengthen mechanism during rolling and heat treatments in the brake beam steel.The strengthening and toughening effects of the three micro-alloying elements were discussed,and the mechanical properties of the new brake beam were analyzed in this paper. The contributions of micro -alloying elements in strengthening and toughening effects of brake beam steels,especially for special -shaped steel,was summarized.更多还原
