METHOD TO PRODUCE SINTERED COMPOSITE MATERIAL ON THE BASE OF TITANIUM DIBORIDE Russian patent published in 1995 - IPC

Abstract RU 2034928 C1

FIELD: powder metallurgy. SUBSTANCE: sintered composite material is made by mechanical activation in planetary mill followed by thermal treatment at 1200 to 1300 C within 30 to 60 min. EFFECT: decreasing temperature by 70 to 100 C and time period of high temperature treatment (sintering), increasing plasticity and resistance to wear, presintered compactability, achieving σизг characteristic equal to 1250 to 1350 MPa, and 87 - 90 Rockweel hardness. 1 tbl
