“…To further study the structure of MnB and the significance of the presence of O, an X-ray photoelectron spectroscopy (XPS) analysis was performed on MnB. As shown in Figure S3, the Mn 2p spectrum of Mn 2 AlB 2 showed different valence states of Mn (Mn metal, Mn 2+ , Mn 3+ , Mn 4+ ), which is consistent with previous studies. , In the spectrum of MnB, an increased presence of Mn 3+ was noted, confirming the existence of MnB. The B 1s spectrum of MnB and Mn 2 AlB 2 further verified the existence of the Mn–B bond (Figure S4).…”

“…important to also understand the wear and friction properties of other MAB-phases such as Mn 2 AlB 2 and their dependence on tribological parameters such as load, speed, and the nature of the sliding partner. [61] Kota et al synthesized dense, singlephase polycrystalline Mn 2 AlB 2 by reactive hot-pressing of manganese, alumina, and boron powder mixtures under vacuum to investigate their thermal, mechanical, and electronic properties. [7] With a Vickers hardness of 8.7 GPa, Mn 2 AlB 2 was identified as relatively soft for a transition metal boride.…”

“…The friction and wear behavior of Mn 2 AlB 2 under dry sliding in ambient conditions was studied dependent on the counter‐body (WC, Al 2 O 3 , Si 3 N 4 , and 100Cr6 bearing steel) using ball‐on‐disc tribometry. [ 61 ] The COF and WR of Mn 2 AlB 2 for ceramic counter‐bodies were shown to increase proportionally with the hardness of the counterpart ( Figure ). It was also demonstrated that adhesive wear and third‐body abrasion led to tribo‐oxidation as the dominant deterioration mechanisms.…”

Early transition metal borides (MAB‐phases) are extensively investigated due to their excellent mechanical and tribological properties. These characteristics of ternary transition metal borides have created a promising pathway to achieve strong materials with unique properties. These layered materials combine both metallic and ceramic attributes and possess intriguing properties such as excellent mechanical, chemical, and thermal stability. Most of the MAB‐phases were discovered before the 1990s, but recent discoveries of their derivatives, such as i‐MAB phases, and MBenes, have boosted their “renaissance.” Altogether, this perspective summarizes the existing state‐of‐the‐art regarding the tribological performance of the most promising MAB‐phases and further discusses their success story in potential applications. Since the story of their derivative phases regarding mechanical/tribological applications has just begun, going beyond MAB‐phases is highly promising to explore novel high‐strength materials.

“…The MAB phases can be described by the general formula of (MB) 2z A x (MB 2 ) y (z = 1, 2; x = 1, 2; y = 0, 1, 2) [4,5]. They are thermally stable [6,7] electrically conductive [8][9][10], oxidation-resistant materials [11,12], and wear-resistant against steel and Inconel [13][14][15]. Moreover, they showed crack-healing behavior [16], magnetocaloric properties [17,18], and damage tolerance [19].…”

Fe 2 AlB 2 is one of many ternary transition metal borides called MAB phases, which attracted interest owing to its magnetocaloric effect and magnetic properties. Herein, the molten salt shielded synthesis (MS 3 ) of Fe 2 AlB 2 powder is studied using potassium bromide "KBr" in an open-air atmosphere. The synthesis process of the MAB phase, from Fe, Al, and B elemental powders, was studied with and without Sn additive in the temperature range of 900-1200°C. The obtained powders were analyzed using XRD, TDA, GTA and SEM analysis. The corresponding results revealed a successful synthesis of nearly-pure Fe 2 AlB 2 phase at 1000°C for only one hour of holding time, beyond which FeB impurities form. These results show the e ciency of KBr (with Sn as a synthesis aid 'additive') in increasing the reactivity of this MAB phase in terms of the lowest synthesis temperature and time reported to date.
