Trosnikova, P. I. Loboda, O. P. Karasevska, O. I. Bilyi // Powder Metallurgy and Metal Ceramics. – 2014. – Vol. 52, Nos. 11-12. – Pp. 674–279.https://ela.kpi.ua/handle/123456789/41612Translated from Poroshkovaya Metallurgiya, Vol. 52, No. 11–12 (494), pp. 80–87, Nov.-Dec. 2013By optical and scanning electron microscopy and quantitative X-ray diffraction and X-ray analysis revealed that the increase in the rate of cooling during crystallization from the melt leads to a reduction in the size of the phase components of the alloy of 20 wt.% WC-80 wt.% W2C, increased compressive stress in the matrix phase W2C and stretching inclusions in the WC, which leads to an increase in the hardness of 1.5 times and 2-4 times the strength of relit, that is used on an industrial scale for the strengthening of machine parts and mechanisms operating in abrasive wear and high contact loads.en© 2014, Springer Science + Business Media New Yorktungsten carbidecooling ratestresseshardnessgrain-boundary strengthening mechanismкарбіди вольфрамушвидкість охолодженнямакронапруженнятвердістьмеханізм зернограничного зміцненняArticlePp. 674-679https://doi.org/10.1007/s11106-014-9576-4621.762
