To illustrate this concept, various concentrations of molybdenum − (Mo) in WB4, that is, W1−xMoxB4 (x = 0.00 0.50), were systematically synthesized by arc melting from the pure elements. The as-synthesized samples were characterized using energy-dispersive X-ray spectroscopy (EDS) for elemental analysis, powder X-ray diffraction (XRD) for phase identification, Vickers microindentation for hardness testing, and thermal gravimetric analysis for determining the thermal stability limit. While the EDS analysis confirmed the elemental purity of the samples, the XRD results indicated that Mo is completely soluble in WB4 over the entire concentration range studied (0−50 at. %) without forming a second phase. When 3 at. % Mo is added to WB4, Vickers hardness values increased by about 15% from 28.1 ± 1.4 to 33.4 ± 0.9 GPa under an applied load of 4.90 N and from 43.3 ± 2.9 to 50.3 ± 3.2 GPa under an applied load of 0.49 N.

  • Performance and Wear Mechanisms of Novel Superhard Diamond and Boron Nitride Based Tools in Machining Al-Sicp Metal Matrix Composite
    Performance and wear mechanisms of novel superhard diamond and boron nitride based tools in machining Al-SiCp metal matrix composite Volodymyr Bushlyaa*, Filip Lenricka, Oleksandr Gutnichenkoa, Igor Petrushab, Oleksandr Osipovb, Stefan Kristianssonc, Jan-Eric Stahla aDivision of Production and Materials Engineering, Lund University, 221 00 Lund, Sweden bDepartment of Synthesis and Sintering of Superhard Materials, Institute for Superhard Materials, 04074 Kiev, Ukraine cAmtek Components Sweden AB, Aspenäsgatan 2, 521 51 Floby, Sweden Abstract Metal matrix composites are the desired materials in aerospace and automotive industries since they possess high specific strength. However addition of reinforcement to the matrix material brings the adverse effects of high wear rate of tool materials used in their machining. The current study addresses the issues of wear and performance of superhard tools when high speed machining cast Al-Si alloy reinforced with particulate SiC (20% vol.). A wide range of developed superhard materials was compared to the commercial PCD tools. Nano grain sized wBN-cBN, binderless cBN; B6O-cBN, nano- diamond with WC binder; diamond/MAX-phase; and diamond/SiC tool materials were employed. Tool wear tests involved dry machining at cutting speeds 200 and 400 m/min at fixed cutting length of 14 000 meters. Use of nano-diamond/WC and diamond/MAX-phase composites resulted in their rapid deterioration due to primarily adhesive pluck-out of diamond and binder phase. Diamond/SiC material exhibited slightly lower performance than the PCD, with the primary wear being the abrasive on the SiC binder phase. Machining with cBN-based tooling at lower speed lead to formation of stable build-up layer, frequently accompanied by severe seizure of tool and workpiece material.

INTRODUCTION Cubic boron nitride (cBN)-based polycrystalline superhard materials, having strength properties comparable to those of diamond composites, are superior to diamond composites in temperature and chemical stability. Over time since the synthesis of cBN micropowders became commercialized, a fairly wide range of cBN micropowder-based superhard materials has been developed. It should be stressed that when sintering the cBN micropowders, high pressures are necessarily used to prevent a reverse phase transition of the micropowders from a diamond-like to soft graphite-like structure. A successful sintering of cBN powders without activating additives can be performed at pressures of no less than 7.0 FHa. Therefore the sizes of the compacts produced in the above way cannot be large due to limited dimensions of the working volumes of high pressure apparatus capable of generating such high pressures.

  • A Novel Superhard Tungsten Nitride Predicted by Machine-Learning Accelerated Crystal Structure Searching
    A novel superhard tungsten nitride predicted by machine-learning accelerated crystal structure searching Kang Xia1, Hao Gao1, Cong Liu1, Jian Sun1, , Hui-Tian Wang1, † & Dingyu Xing1 ∗ 1National Laboratory of Solid State Microstructures, School of Physics and Collaborative Innovation Center of Advanced Microstructures, Nanjing University, Nanjing, 210093, P. R. China. Abstract Transition metal nitrides have been suggested to have both high hardness and good thermal stability with large potential application value, but so far stable superhard transition metal nitrides have not been synthesized. Here, with our newly developed machine-learning accelerated crystal structure searching method, we designed a superhard tungsten nitride, h- WN6, which can be synthesized at pressure around 65 GPa and quenchable to ambient pressure. This h-WN6 is constructed with single-bonded N6 rings and presents ionic-like 2.4+ 2.4- features, which can be formulated as W N6 . It has a band gap of 1.6 eV at 0 GPa and exhibits an abnormal gap broadening behavior under pressure. Excitingly, this h-WN6 is found to be the hardest among transition metal nitrides known so far (Vickers hardness around 57 GPa) and also has a very high melting temperature (around 1900 K). These predictions support the designing rules and may stimulate future experiments to synthesize superhard material. Kang Xia and Hao Gao contributed equally to this work. Correspondence and requests for materials should be addressed to J. S. (email: [email protected]) or H. T. W. (email: [email protected]) 1 Transition-metal nitrides (TMNs) are promising candidates for new ultra-hard materials1–5, due to their outstanding properties, such as comparable thermodynamic stability to cubic γ-Si3N4, high melting points, good chemical inertness, high incompressibility and hardness, as well as their better performance in cutting ferrous metals than diamond6.

Naturforsch. 61b, 1555 – 1560 (2006); received July 13, 2006 This work reports a new route for preparing cubic BN (c-BN) nanocrystals under moderate con- ditions. Considering the instability of BN nanoparticles, we have investigated the structural trans- formation of BN nanoparticles in benzene. The results revealed that a great deal of hexagonal BN (h-BN) nanoparticles had been converted into c-BN or wurtzitic BN (w-BN) at 280 ◦C and 50 MPa. As the temperature was increased from 280 to 300 ◦C, h-BN nanoparticles gradually disappeared, and the content of both c-BN or w-BN increased. Similarly, increase of pressure or hot-pressing time showed the same effect. These results may open up an opportunity for synthesizing other superhard nanomaterials such as diamond and cubic carbon nitride under moderate conditions. Key words: Boron Nitride Nanoparticles, Solvent Hot-pressing Route, Structural Transformation, Characterization Introduction h-BN nanoparticles could be converted into c-BN at 270 – 325 ◦C and 0.6 – 0.9 GPa [19].
