CAKED SOLID ALLOY ON THE BASIS OF REFRACTORY METAL CARBONITRIDE Russian patent published in 1995 - IPC

FIELD: powder metallurgy. SUBSTANCE: alloy has, wt.-% Ni 1.2-13.6; Co 4.5-24.8; Mo 0.005-3.2; W 0.01-14.7; complex carbonitride of the formula W_xMo_yTi_zTa_kC_δN_ε 2.3-30.8, and titanium carbonitride the rest at x=0.28-0.91; y= 0.005-0.46; z=0.005-0.077; k=0.008-0.255; d 0.34-0.995; e 0.005-0.66; x + y + z 1.0. Alloy shows the following mechanical properties: s 1600-2320 MPa, hardness is 89.0-92.8 HRA, a 0.25-0.78 kg/сm². Wear-resistance K is increased by 1.3-6.8 times. EFFECT: increased working stability of cutting tool made of proposed alloy. 1 tbl
