| Abstract: | The effect of cooling rate on structure and properties of wear-resistant low chromium cast iron after 40 %hot deformation was investigated by metallographic and scanning electron microscope.The results show that the cooling rate is closely related to the structure and properties,and for the cast iron,the best comprehensive me chanical properties were obtained by forced air cooling with a cooling rate as about 7 C/s.The reason and regularity for the change of mechanical properties were analyzed. |
| Keywords: | cooling rate hot deformation structure property wear resistance low chromium cast iron |
