“…Concerning the ternary system, four isothermal sections, at 1450, 1290, 1175 and 1050°C from Ottavi et al [30] and from A. Antoni-Zdziobek et al [31] have been used in the optimization, as well as one vertical section, at molar ratio x B :x Ti = 2 from Ottavi et al [30] and Shurin and Panarin [32]. Moreover, experimental data of the Fe-Ti phase equilibria [7,14,15,[33][34][35][36][37][38][39][40][41][42][43][44][45][46], the mixing enthalpy of liquid Fe-Ti alloys [47][48][49], the chemical potentials of Fe and Ti in the liquid alloys [50,51], and the enthalpy of formation of Fe 2 Ti and FeTi [52,53] were used for the partial re-optimization of the Fe-Ti system.…”

“…An inconsistency between the experimental data from [30] and [31] resulting in different eutectic temperatures and compositions (given by the bending points of the dotted lines of the figure) is seen in Figure 12. The best compromise found in the process of optimization was to use preferably the L/L + TiB 2 data from [30] and the eutectic temperature by Shurin and Panarin [32].…”

Thermodynamic optimizations of the ternary Fe-B-Ti system and its binary sub-system, B-Ti are presented. The thermodynamic descriptions of the other binaries, Fe-Ti and Fe-B, are taken from the earlier studies slightly modifying the Fe-Ti system assessment. The adjustable parameters of the Fe-B-Ti and B-Ti systems are optimized in this study using the experimental thermodynamic and the phase equilibrium data from the literature. The solution phases of the system are described using the substitutional solution model and the compounds (including borides) are treated as stoichiometric phases. The results show a good correlation between the calculated and measured thermodynamic and phase equilibrium data.

“…Case hardening of alloys or intermetallic compounds is often obtained by interstitial alloying. Here, the interstitial sites of the host lattice are occupied by small atoms, such as carbon, oxygen, nitrogen, boron or even noble gases like helium or neon. − From the art of ancient blacksmithing to the modern engineering of high-performance materials, there is a long list of surface hardening techniques, ranging from simple carburization of iron swords in B.C. times to current laser sintering of ultrahard materials …”

Increasing the Wear Resistance by Interstitial Alloying with Boron via Chemical Vapor Deposition

et al. 2013

The wear resistance of a Rh(111) surface can be strongly increased by interstitial alloying with boron atoms via chemical vapor deposition of trimethylborate [B(OCH3)3] at moderate temperatures of about 800 K. The fragmentation of the precursor results in single boron atoms that are incorporated in the fcc lattice of the substrate, as displayed by X-ray photoelectron diffraction. The penetration depth of the boron atoms is in the range of at least 100 nm with the boron distribution displaying a nearly homogeneous depth profile, as examined by combined X-ray photoelectron spectroscopy and Ar ion etching experiments. Compared to the bare Rh(111) surface, the wear resistance of the boron-doped Rh surface is increased to about 400%, as probed by the scratching experiments with atomic force microscopy. The presented synthesis route provides an easy method for case hardening of micro- or nanoelectromechanical devices (MEMS and NEMS, respectively) at moderate temperatures.

“…The SMC sample was prepared using FeTi, FeB and pure iron powders melted at 1650 o C and solidified at a rate of 10 o C s À1 in a vacuum environment under a confocal laser scanning microscope. With this chemical composition, SMCs can be produced by eutectic solidification, as shown in the Fe-TiB 2 phase diagram [11]. The density of the SMC was measured by a hydrostatic weighing method [12] using distilled water and an AUY120 Shimadzu electronic balance with an accuracy of ±0.0001 g. Scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) were employed to characterize the microstructure.…”
