Effect of η-phase and FeAl composition on the mechanical properties of WC–FeAl composites

Correlations between Structural and Hardness of Fe-50%Al Coating Prepared by Mechanical Alloying

“…Risanti et al show that intermetallic phase is brittle at the room temperature [21]. Study on WC-FeAl composite by Furushima et al revealed that the Vickers hardness is influenced by the generation of the h-phase [22]. The hardness value of Fe-50%Al coating in this study is smaller than the FeAl intermetallic (470 Hv) as presented by Ozaki and Kutsuna [23].…”

Design of alternative binders for hard materials

“…For Fe15Cr10Al-Ti(C,N) system, contact angle test was carried out 50 °C higher than for the first composition, as simulated and DTA (sintered bulk) liquid-formation temperatures were higher for this composition. As it can be appreciated in Figure 11, the metal sample did not reach its melting point, probably due to oxidation that this particular alloy composition may be experiencing [36], and a contact angle could not be measured.…”

High-temperature wettability in hard materials: Comparison of systems with different binder/carbide phases and evaluation of C addition

“…As explained in the cited publication and compiled in Table 2, the test was carried out up to 1650 • C, as simulated and DTA (sintered bulk) liquid-formation temperatures were higher for this composition [34]. Nevertheless, the metal sample did not reach its melting point, probably due to oxidation that this particular alloy composition may experience [16]. There was not any droplet formation; hence, a contact angle could not be measured.…”

“…Furthermore, its inclusion as a binder element in WC-based materials has resulted in enhanced mechanical properties [13]. The addition of alloying elements, such as Cr, Ni or Al, has also demonstrated to improve oxidation [14][15][16][17] and corrosion [13,15,[18][19][20][21][22][23][24][25][26][27][28][29] resistance of these materials, among other properties. Concerning the substitution of the ceramic phase, titanium carbonitride -Ti(C,N) -cermets, have arisen as very promising options, on the basis of providing advantages like high wear resistance or chemical stability [30].…”
