Utkin, Registration Date 17-03-2006 Organization I.N.Frantsevich Institute for Probmens of Materials Sciences Ukrainian Academy of Science popup.description2 Boride Mo2NiB2 alloyed with Cr is perspec- tive to create hard alloys. Samples of (20,5-28)Mo - (39,5-32)Ni - 10Cr - 30B (at. %) were sintered at 1260°С. It was observed high-disperse homogeneous structure formed of tetragonal (Mo,Ni,Cr)3B2 and <Ni> phase. M3B2 microhardness is ~ 20 ГПа, of <Ni> - 4-5 ГПа. Rockwell hardness is 81-84 HRA (comparable to WC-Co alloys), and density is 7,6-7,8 г/см3 (~2 times less).
