A first-principles-calculation exploration of ternary borides as potential alternatives to WC-Co

The thermodynamic and mechanical properties of Earth-abundant metal ternary boride Mo2(Fe,Mn)B2 solid solutions for impact- and wear-resistant alloys

“…The averaged H V values (Fig. 16(c)) show small differences with respect to the method (CE or VCA) used for the solid solutions models, and the calculated values are in good agreement with the results of the performed experimental measurements for the key alloys ( x = 0 and x = 0.25), experimental data from, 11 and also closely match the calculated data from 11,12,15 when considering mean values of H V .…”

“…A comprehensive analysis of the experimental investigations 3,4,6,7 and theoretical studies 9–12,15,16 of Mn 2 FeB 2 and similar compounds shows that current investigations mainly focus on these compounds in their pure state. However, there is a lack of data regarding the properties of their based solid solutions.…”

Reactive synthesis and phase evolution of W2FeB2 alloy powders

“…Since the W 2 FeB 2 phase might exist in forms of tetragonal or orthorhombic crystal structure, 16 so the alloy powders (1150 °C for 3 h) had been investigated by TEM in order to confirm the real crystal structure. The results in Fig.…”

Structure and properties of the films based on ternary transition metal borides: theory and experiment

“…In [18], the crystal structures, mechanical properties and Debye temperatures of 18 transition metal ternary borides M I 𝑥 M II B 𝑥 (𝑥 = 1 or 2, M I and M II are transition metals) were studied through first-principle calculations. The thermodynamic stability of the ternary borides crystal structures was estimated by the cohesive energy (𝐸 coh ) and formation enthalpy (Δ𝐻 r ).…”
