YF06 carbide nano powder compression properties of

Compacting pressure and relative density compacts the first three weeks the book to help other: YF06 carbide nano powder compression properties of more teaching Yong 0.16810l11J1 () 182 () compacting pressure,[link widoczny dla zalogowanych], kN / clit: ~ Figure 5, two powder compacting pressure and the elastic aftereffect coefficient in the YF06 powder compacting pressure and the relationship between the relative density of compacts was: Y = 6.930 +0.822 xX (4) where, Y a pressing pressure in kN / cm; X an Compacts elastic aftereffect coefficient (%). From (3) and (4) can also be seen powder compacts of nano YF06 aftereffect coefficient of elasticity increases with the compaction pressure increased dramatically,[link widoczny dla zalogowanych], more (3) and (4) the slope can be seen, YF06 powder YT5 than normal carbide powder compacts elastic aftereffect much larger. (1) and (2) in the suppression of pressure (2 ~ 15) kN / cm to fit inside the range. Figure 6 Two powder compacts with green density elastic aftereffect increases rapidly,, YF06 density of powder compacts reached 50% after the green density is difficult to increase the pressure in the large suppression be a huge elastic aftereffect. 4 Conclusion l,[link widoczny dla zalogowanych], YF06 PEG nano-cemented carbide powder is spray granulation and bulk density increase liquidity and improve the performance of its suppression; can get 50% of the relative density of compacts. Water 2 () J5 cut 10 songs i30 ~ t0506070 compacts relative density,% Figure 6, the relative density of compacts and compacts between elastic aftereffect coefficient of 2, YF06 carbide nano powder compaction pressure than normal carbide powder Multi-suppression pressure; and with the increase of green density increases rapidly; the relative density of compacts 54% 1t. 1 -, compacting pressure is normal pressure on the suppression of carbide powder 9 times. 3,[link widoczny dla zalogowanych], YF06 elastic aftereffect of nano cemented carbide powder carbide powder than normal elastic aftereffect is also large; when the green density more than 50%, the increase in green density is difficult to suppress the increase of pressure can only increase elastic aftereffect.
