Ukuhlalutya i-Inconel 718 Powder yoShicilelo lwe-3D

(Uhlalutya i-Inconel 718 Powder yoShicilelo lwe-3D)

Ngokwemveli, i-Inconel 718 iveliswe ngokunyibilika kwevacuum induction. Nangona kunjalo, iye yanda kakhulu kwintsimi yokuvelisa ezongezelelweyo. Isetyenziswa kwizicelo zobunjineli ezahlukeneyo, kubandakanya iinjini ze-aero kunye nezixhobo zerokhethi ezinolwelo. Amandla ayo abalaseleyo okudinwa kunye nokumelana nokubola kwenza ukuba ilungele ezi zicelo.

Ukuze uhlalutye imilo, i-morphology kunye ne-physico-chemical properties of four states of Inconel 718 powder, i-FESEM isetyenziswe. Imakroskopu ye-Optical nayo yasetyenziswa ukujonga ubume bangaphakathi kunye neziphene. Imifanekiso icutshungulwe nge-ImageJ 1.53a software kunye ne-SEM / BSE ukubala ukusabalalisa ubungakanani be-particle.

Iziphumo zibonise ukuba ubunzima beengqungquthela zepowder abuzange buhluke kakhulu phakathi kweepowder states. Ubulukhuni obuqhelekileyo bamaqhekeza buphakathi koluhlu lwe-240-250 HV. Eli xabiso liphawu lwe-Inconel 718 efakiweyo kwaye ayibalulekanga ngokwezibalo.

Iziphumo zibonisa ukuba ubuninzi obuqhelekileyo bepowder yi-60%. Ubuninzi bobuninzi bulinganiswa ngeegremu kwi-cubic meter nganye. Ubuninzi obubonakalayo bulinganiswa ngokwemigangatho ye-ASTM B212. Ubuninzi be-tapped bubalwa ngokwahlula ubunzima bepowder kwindebe ngomthamo wayo.

Uvavanyo lwe-rheological lubandakanya uvavanyo lokucheba, uvavanyo lokuhamba okuguquguqukayo, uvavanyo lokuzinza, kunye novavanyo lokukhuhlana eludongeni. Iziphumo zibonisa ukuba i-Inconel powder eyintombi inokuhamba kakuhle. Kucetyiswa ukuba uphucule ngakumbi umgubo wokuhamba kakuhle.

Iziphumo zikwabonisa ukuba ukuqina kunye namandla okuqina komgubo kulungile. Ezi zakhiwo zibonisa ukuba i-Inconel powder yangoku iyamkeleka kwi-3D yokushicilela. Amandla esivuno somgubo ayancipha xa ephantsi kobushushu obuphezulu.
