| Abstract: | The effect and mechanisms of Fe - RE alloy on the mechanical properties and microstructure of steel bonded with TiC were investigated in this paper. The results showed that a steel with a high density and good mechanical properties can be obtained by the addition of Fe - RE that can decrease the surface tension of the 1 iquid iron, and increase the density and hardness of steel bonded TiC by means of changing the distribution and state of impurity, improving liquid fluidity and wettability, and refining the grains. |
