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 kobudala obuphakathi, i-Inconel 718 inokudityaniswa kwiimeko ezifakwe i-anneal kunye nezo zigugileyo ngaphandle komngcipheko omkhulu. I-alloy ibonakalisa 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-salty 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 isebenze ngobushushu obuphantsi kusetyenziswa iindlela eziqhelekileyo. Ukusebenza ngobushushu obuphantsi kwandisa kakhulu amandla ngelixa kugcinwa ukuguquguquka okwaneleyo. Ingxubevange iyakwazi ukucutshungulwa kusetyenziswa i-carbide okanye izixhobo ze-ceramic ezineeparameter ezifanelekileyo.

Q: Ngaba i-Inconel 718 ifuna unyango lobushushu?

A: Ewe. I-Inconel 718 ifumana amandla ayo angaqhelekanga ngonyango lobushushu oluqinisa imvula. Inkqubo eqhelekileyo kukucoca 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.
