GH1140 alloy

GH1140 siab kub alloy yog ib qho khoom siv ntxiv dag zog rau hlau-nickel raws li kub kub alloy. Ntxiv nrog rau qhov muaj ntau ntawm chromium, nws kuj tseem siv me me ntawm tungsten, molybdenum, aluminium thiab titanium kom ntxiv dag zog rau cov khoom siv. Cov alloy muaj nruab nrab thermal zog, siab plasticity, zoo thermal qaug zog, lub koom haum stability thiab vuam txheej txheem kev ua tau zoo. Nws yog qhov tsim nyog rau kev tsim cov phaj txheej txheem thiab lwm qhov chaw kub ntawm cov tshuab dav hlau thiab cov roj turbine combustion chambers nrog kev ua haujlwm kub hauv qab 850 degree. Ntau yam khoom deformed xws li daim hlau, pas nrig, raj, xaim, strips thiab forgings tuaj yeem muab tau.

GH1140 tshuaj muaj pes tsawg leeg raws li GB/T 14992-2005 tus qauv:

1. Cov txheej txheem kub txheej txheem:
(1) Lub qhov cub kub thaum lub sij hawm forging yog tsawg dua los yog sib npaug li 700 degree, qhov cua kub yog 1160 degree ± 20 degree, thiab lub davhlau ya nyob twg kub tsis tsawg tshaj li 900 degree.
(2) Cov cua kub kub ntawm cov slab kub dov yog 1160 degree ± 20 degree, dov kub yog 1180 ~ 950 degree, thiab qhov kub zoo dua yog tswj nyob rau hauv thaj tsam ntawm 950 ~ 1000 degree thaum nkag mus rau qhov kawg dhau.
(3) Cov cua kub kub ntawm lub phaj kub dov yog 1120 degree, dov kub yog 1120 ~ 850 degree, thiab tag nrho cov deformation ntawm cov kub dov phaj yog ntau dua 50%.
(4) Qhov txias dov phaj dov txo yog 30% ~ 40%, thiab lub tiaj tus deformation ntawm cov phaj tiav yuav tsum tsis pub tshaj 3%.
2. Kev ua haujlwm txias txias:

Lub xeev ntawm lub phaj muaj cov yas zoo, thiab cov txheej txheem tsim yog nqa tawm ntawm chav tsev kub. Thaum tsim cov khoom los ntawm ntau txoj kev tsim, nruab nrab thiab kev kho cua sov yog ua tom qab txhua qhov txias txias. Qhov saum npoo ntawm ib feem yog coated nrog nitro kua roj vanish ua ntej sib sau.

GH1140 alloy yog nickel-based high-temperature alloy nrog cov tshuaj zoo heev. Ua ntej, nws muaj kev tiv thaiv corrosion zoo thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev nyob rau hauv qhov kub thiab txias, siab siab thiab corrosive ib puag ncig. Qhov thib ob, GH1140 alloy muaj lub zog siab thiab hardness, thiab tuaj yeem tiv taus cov khoom hnyav thiab cuam tshuam ntawm qhov kub thiab txias. Tsis tas li ntawd, nws kuj muaj qhov kub thiab txias oxidation thiab kub corrosion kuj, thiab muaj peev xwm tswj tau kev ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub thiab txias. Lub thermal expansion coefficient ntawm GH1140 alloy yog ze rau ntawm cov hlau, uas tuaj yeem txo qhov kev ntxhov siab thiab deformation los ntawm thermal expansion. Tsis tas li ntawd, cov thermal conductivity ntawm GH1140 alloy yog qhov tsawg, uas tuaj yeem tiv thaiv cov cua sov kom zoo, tso cai rau nws kom muaj qhov kub thiab txias hauv qhov kub thiab txias. Feem ntau, cov khoom siv tshuaj lom neeg ntawm GH1140 alloy ua rau nws zoo tagnrho cov khoom siv hluav taws xob kub kub, uas yog siv dav hauv aerospace, lub zog thiab tshuaj lom neeg kev lag luam.
