“…Fortunately, the additional alloying of Fe-Al with Cr boosts the formation of the Al oxide scale on the surface up to such a level that the Al content in bulk can be kept within the acceptable limits regarding to the required mechanical properties of the alloy. This phenomenon, called the third element effect, is still considered a phenomenon without generally accepted explanation (Badini & Laurella, 2001;Götlind et al, 2007;Niu, Wang, Gao, Zhang, & Gesmundo, 2008;Stott, Wood, & Stringer, 1995;Z. G. Zhang, Gesmundo, Hou, & Niu, 2006).…”

“…However, the Al 2 O 3 film is easy to peel off during the thermal cycling process, which reduces the oxidation resistance of the alloy [2][3][4]. Fe-Cr-B alloy has better quenching hardenability, quenching hardness and wear resistance compared with conventional high chromium white cast iron [5,6], but it has poor oxidation resistance at high temperatures.…”

The effect of tempering on the microstructure, mechanical properties and wear resistance of cast Fe-10wt.%Cr-1.5wt.%B-2wt.%Al (referred to as Fe-Cr-B-Al) alloy after quenching at 1100• C has been investigated in the present study. The results show that microstructure of tempered Fe-Cr-B-Al alloy consists of tempered martensite, massive ferrite and discontinuous eutectic borocarbide. With the increasing tempering temperature, the retained austenite is gradually transformed into martensite. When the tempering temperature is higher than 450• C, the content of ferrite in the matrix increases gradually, however, the content of martensite decreases gradually. There was no significant change in the morphology of borocarbide. With the tempering time (4-12 h) and tempering cycle increasing, the content of ferrite in the matrix increases gradually. When the tempering temperature is lower than 450• C, the hardness of Fe-Cr-B-Al alloy has no obvious change. With the increasing temperature, the hardness gradually decreases. The hardness of Fe-Cr-B-Al alloy almost reaches the highest value after once tempering and decreases slightly after tempering for two or three cycles. With the extension of tempering time, it is beneficial to the precipitation of carbide, and the hardness of Fe-Cr-B-Al alloy increases gradually. When the tempering time is too long, the hardness begins to decrease. Fe-Cr-B-Al alloy has excellent wear resistance while quenching at 1100• C and tempering at 450 • C; the main wear mechanism is cutting wear and ploughing effect.

“…1) Hence, the high cost and the low hardness of Ni or Co and the low corrosion resistance of the (W,Ti)C-Ni or (W,T)C-Co cermet have generated interest in recent years to find alternative binder phases. 2,3) It has been reported that aluminides show a higher oxidation resistance, a higher hardness and a cheaper materials compared to Ni or Co. 4) The improvement of mechanical properties and stability of cemented carbides could be achieved through microstructural changes such as grain size refinement. 5,6) Nanocrystalline materials have received much attention as advanced engineering materials with improved physical and mechanical properties.…”
