| Abstract: | By means of analysis of microstructure and measuring of impact toughness and hardness, and verification by real manufacture and application, the Si-Mn steel with rare earth and boron complex modification is better than traditional high Mn steel to produce tractor track guard in the wide range of temperature and the low cost and long life. So the economic and social benefits of the new materials are very obvious. |
