Abstract
- The microstructures of Fe-B alloys containing different carbon and boron concentrations have been investigated. The solidification microstructures of Fe-B alloy consist of the eutectic boride, pearlite, and ferrite. Borides precipitate along the grain boundary during the formation of eutectic. After heat treatment, the phases in Fe-B alloy are composed of the boride and martensite. With increase of carbon and boron concentrations, the Rockwell hardness of Fe-B alloy becomes larger. Meanwhile, by using a pin-on-disk abrasion tester, the effects of carbon and boron concentrations on the wear behaviors including ploughing depth, roughness, and wear weight loss under different loads have been studied. The results show that the wear resistance of Fe-B alloy with higher carbon and boron concentrations is comparable with the high chromium white cast iron. [ABSTRACT FROM AUTHOR]
