| Abstract: | Solid 45 steel rods were cast in the center of Cr white cast iron rods, resulting in composite specimens, and the structures and properties of them were in-vestigated. The better combination of strength and hardness can be obtained by means of larger diameter ratio of steel, Cr white cast iron and proper heat treatment. The highest hardness of the composite is HRC 61. 5-64. 5, and the largest bendingstrength is 700-l000MPa which is 40% higher than that of common Cr white cast iron. Also,some technology parameters were discussed. |
