Effect of Carbon Addition on Tribological Properties of Fe-Al Alloys S.M. ZHU, K. SHIBATA, X.S. GUAN, and K. IWASAKI Although the physical properties, mechanical behavior, and corrosion resistance of iron aluminides (Fe3Al and FeAl) have been extensively studied in the past decades, only a few studies have been conducted aimed at understanding and improving the wear properties of these alloys.[1–4] In fact, iron aluminides possess many attributes necessary for wear resistance—high hardness, high elastic modulus, and good environmental resistance—and thus are promising as tribological materials for use in aggressive environments at

elevated temperatures. It has been shown by Hawk and Alman[2] that Fe3Al has wear resistance similar to those of a variety of steels, for example, 304 SS and 316 SS. They also found that the addition of Ti to Fe3Al has a positive influence on the tribological properties. However, our previous work has shown that the addition of Ti into iron aluminides tends to reduce their room-temperatur
