【Abstract】 Mixed matrix structure was obtained by intensifying inoculation to increase the S.G. count, reduce the segregation of manganese ,and,simultaneously , by adopting relatively high content of silicon which together with manganese acted as strengthening elements. As a result a high level of properties with σb>600Mpa and δ>10% was reached.更多还原
