| Abstract: | The result shows that composite containing 2.5% Si and 1.8%Mn possesses a self-quenching characteristic when it is poured with wet sand mould. Namely, the as-cast structure of its matrix was totally martensite or a mixture of martensite and pearlite. After heat-treatment, it consists of only martensite. When 2.7% Ti is added into the composite, the highest as-cast hardness is 55 HRC. When composite is heatly treated, the hardness is 59.9 HRC, and impact toughness is 9.17 J/cm~2. |
