I-Inconel® 718 yingxubevange yenickel-chromium eyenza imvula ibe lukhuni.amandla aphezulu kunye ne-ductility elungileyo ukuya kuthi ga kwi-1300 ° F (704 ° C).le Alloy equlethe izixa ezibalulekileyo zentsimbi, i-columbium, kunye ne-molybdenum, kunye nezixa ezingaphantsi ze-aluminiyam kunye ne-titanium.I-Nickel 718 nayo ine-weldability efanelekileyo, ukwakheka, kunye neempawu ezigqwesileyo ze-cryogenic xa kuthelekiswa namanye ama-alloys e-nickel.I-sluggish precipitation yenza lukhuni impendulo yalo mxube ivumela ukuba idityaniswe ngokulula ngaphandle kokuqina okanye ukuqhekeka.Ingxubevange 718 ayinamagnetic.Igcina ukuxhathisa okulungileyo kokubola kunye nokumelana ne-oxidation kwaye isetyenziselwa iindawo ezifuna ukuxhathisa okuphezulu kwi-creep kunye noxinzelelo lwe-stress rupture ukuya kwi-1300 ° F (704 ° C) kunye nokumelana ne-oxidation ukuya kwi-1800 ° F (982 ° C).

I-Inconel 718 yi-Austenitic structure, imvula eyenza lukhuni ivelisa "γ" iyenze yasebenza kakuhle ngoomatshini.Umda wemvula we-G uvelise i-"δ" yenze ukuba ibe yeyona plastikhi igqwesileyo kunyango lobushushu.ngokumelana kakhulu noxinzelelo lokuqhekeka kwe-corrosion kunye nokukwazi ukugoba kubushushu obuphezulu okanye kubume bobushushu obuphantsi, ngakumbi i-inoxidability kwiqondo lobushushu eliphezulu.
1.ukusebenza
2.Amandla okuqina aphezulu, amandla okunyamezela, amandla okurhubuluza kunye namandla okugqabhuka kwi-700℃.
3.I-inoxidability ephezulu kwi-1000℃.
I-4.I-Steady yokusebenza komatshini kwiqondo lokushisa eliphantsi.
Amandla obushushu obunyusiweyo, ukumelana nokugqwesa okugqwesileyo kunye nokusebenza kakuhle kwiipropathi ezingama-700℃ kwenze ukuba kusetyenziswe kuluhlu olubanzi lweemeko eziyimfuneko eziphezulu.Amanqanaba e-Inconel akulungele ukusetyenziswa ekuveliseni amacandelo aqeshwe kwiindawo ezinzima ezifana ne-turbocharger rotors & seals, iishafti zemoto zempompo yombane engaphantsi kwamanzi, iijenereyitha zomphunga, iityhubhu zokutshintsha ubushushu, isandi sompu esicinezela isandi sokuqhushumba kunye nemipu yomatshini. , iirekhoda zebhokisi ezimnyama kwiinqwelomoya njl.
