摘要：
Fe-C-B alloy, with excellent wear resistance and cost-effectiveness, has the potential to become the new generation of wear-resistant materials, whose broad application is limited due to its relatively low toughness caused by meshed boride. The progress of research on Fe-C-B alloy toughening mechanism is reviewed, including adjustment to boron content, heat treatment under high temperature, alloying and modification. It can be suggested that alloys with boron content ranging in 2.0%-4.0% has good performance, as the hardness reaches 60HRC and the impact toughness is about 6 J/cm2. High temperature heat treatment at 1 000-1 050℃ is favorable for alloy toughening. Also, toughness can be improved to a certain extent through alloying or modification. In-depth studies on the toughening mechanism of Fe-C-B alloy are necessary for further improvement of toughness by combining various toughening methods. © 2017, Materials Review Magazine.
