Iingenelo eziphambili ze-Inconel 718
Indlela Yokuqinisa Umvula– I-Inconel 718 ifumana amandla ayo kwimvula ye-γ″ (Ni₃Nb) kunye ne-γ′ (Ni₃(Al,Ti)) ngexesha lonyango lobushushu lokwaluphala. Isigaba se-γ″ yindlela ephambili yokuqinisa, apho iqhekeza levolumu lifikelela malunga ne-12-20%. Ngokungafaniyo nezinye ii-alloys ezininzi zokuqinisa imvula, i-Inconel 718 inempendulo yokuguga ecothayo, inika ithuba elikhulu lokucubungula kunye nokudityaniswa okugqwesileyo.
Amandla Angaqhelekanga Obushushu Obuphezulu– I-Inconel 718 igcina amandla aphezulu okuxinana, ukudinwa, kunye nokuqhekeka kwe-creep ukuya kuthi ga kwi-700°C (1300°F). Kwi-650°C, amandla ayo okuvelisa adlula lawo onke amanye ama-superalloys asetyenziweyo. I-alloy ibonisa ukumelana okuhle kwe-creep kuluhlu lwe-650-700°C, nto leyo eyenza ukuba ibe yeyona nto ikhethwayo kwinkonzo yexesha elide yobushushu obuphezulu.
Ukudityaniswa kakuhle– I-Inconel 718 ithathwa kakhulu njengeyona superalloy inyibilikiswayo esekelwe kwi-nickel. Ngokungafaniyo nee-alloy ezininzi zokuqinisa imvula ezisengozini yokuqhekeka kobunzima, i-Inconel 718 inokudityaniswa kwiimeko ezifakwe i-anneal kunye nezo zigugileyo ngaphandle komngcipheko omkhulu. I-alloy ibonisa ukumelana okuhle kakhulu nokuqhekeka okubangelwa yi-weld kwaye inokudityaniswa kusetyenziswa i-TIG, i-MIG, i-electron beam, kunye neenkqubo ze-laser welding. Amalungu ahlanganisiweyo adla ngokufikelela kumandla esinyithi asondeleyo kumzali ngonyango olulula lokuguga emva kokudityaniswa.
Ubungakanani bobushushu obubanzi– I-alloy igcina iipropati ezizinzileyo ukusuka kumaqondo obushushu angabonakaliyo (-253°C) ukuya kuthi ga kwi-700°C. Kumaqondo obushushu angabonakaliyo, amandla kunye nokuqina kuyanda ngaphandle kokutshintsha kwe-ductile ukuya kwi-brittle, okwenza ukuba ifaneleke kwiinkqubo ze-hydrogen engamanzi kunye ne-oxygen engamanzi. Olu luhlu olubanzi lokusebenza alufumaneki phakathi kwee-superalloys.
Ukumelana kakuhle nokugqwala– Ngomxholo we-chromium oyi-17-21%, i-Inconel 718 inika ukumelana okuhle kakhulu ne-oxidation, i-pitting, kunye ne-stress corrosion cracking kwiindawo ezahlukeneyo. I-alloy isebenza kakuhle emanzini olwandle, kwi-salt spray, kwi-acidic media, nakwii-atmospheres ze-oxidizing ezishushu kakhulu. Umxholo wayo ophantsi we-cobalt (≤1.0%) wenza ukuba ifaneleke ukusetyenziswa kwenyukliya apho ukusebenza kwe-radiation kuyingxaki.
Ukwenziwa kakuhle kakhulu– I-Inconel 718 ingasebenza ngobushushu obuphezulu kwi-900-1150°C kwaye iyasebenza ngobushushu obuphantsi kusetyenziswa iindlela eziqhelekileyo. Ukusebenza ngobushushu obuphantsi kwandisa kakhulu amandla ngelixa kugcinwa ukuguquguquka okwaneleyo. I-alloy iyakwazi ukucutshungulwa kusetyenziswa i-carbide okanye izixhobo ze-ceramic ezineeparameter ezifanelekileyo.

A: I-Womic Steel ibonelela nge-Inconel 718 ngepayipi engenamthungo, ipayipi edibeneyo, ibha yentsimbi, ipleyiti yentsimbi, ikhoyili yentsimbi, umcu, iiflanges, izixhobo, izixhobo zokufakelwa, ucingo, izipringi, izibophelelo, kunye neevalvu. Iinkcukacha ezipheleleyo zemveliso kunye noluhlu lobungakanani zidweliswe kwicandelo lokufumaneka kwemveliso.
Q: Ngaba i-Inconel 718 ifuna unyango lobushushu?
A: Ewe. I-Inconel 718 ifumana amandla ayo angaqhelekanga ngonyango lobushushu oluqinisa imvula. Inkqubo eqhelekileyo kukuncedisa isisombululo (927-1010°C) kulandele ukuguga kabini (718°C iiyure ezisi-8, i-furnace iphole ukuya kuma-620°C, ibambe iiyure ezisi-8-10).
Q: Ingaba i-Inconel 718 inamandla emagnethi?
A: Hayi. I-Inconel 718 ayisebenzisi magnethi kuzo zonke iimeko, nto leyo eyenza ukuba ifaneleke ukusetyenziswa apho kufuneka kuthintelwe ukuphazamiseka kwemagnethi.
Q: Ingakanani intsebenzo yokudinwa ye-Inconel 718?
A: I-Inconel 718 ibonakalisa ukumelana nokudinwa okumangalisayo kumaqondo obushushu aphezulu. Umda wayo wokudinwa okuphezulu (HCF) kwi-650°C udlula i-400 MPa, nto leyo eyenza ukuba ifaneleke ukusetyenziswa phantsi komthwalo ojikelezayo kunye nokudinwa kobushushu.
