| Abstract: | By means of orthogonal experiment for chemical compositions,the compositions of as-cast manganese steel were obtained.On the basis of systematic experiments for the modification agents,a suitable RE-Mg-Ba complex modifying agent was found for the steel.The optimum compositions and modification procedure result the formation of a metastable austenitic matrix and evenly distributed hard carbides in the as-cast manganese steel.The steel has a higher initial hardness,a stronger work-hardening ability, sufficient impact toughness and good wear resistance. |
