718 Inconel yog dab tsi?
Inconel 718 (los yog Alloy 718) yog qhov siab -lub zog, nag lossis daus-hardenable, npib tsib xee-chromium superalloy paub txog nws qhov tshwj xeeb lub zog, corrosion kuj, thiab weldability, tshwj xeeb tshaj yog nyob rau hauv huab cua kub los ntawm cryogenic qib mus txog ib ncig ntawm 1300℃F (700 degree). Nws yog cov hlau ua haujlwm siv dav hauv aerospace ( dav hlau tshuab, foob pob hluav taws), roj & roj, thiab kev lag luam nuclear rau cov khoom tseem ceeb xws li fasteners, turbines, thiab cryogenic cia.
ASTM sib npaug ntawm Inconel 718 yog dab tsi?
ASTM cov qauv sib npaug rau Inconel 718 txawv nyob ntawm daim ntawv khoom. Sawb / phaj siv ASTM B670, thaum bar Tshuag siv ASTM B637. Ob qho qauv npog tib lub siab -lub zog npib tsib xee alloy (UNS N07718), paub txog nws qhov kev ua haujlwm siab- kub, thiab cov hlau no kuj ua raws li cov khoom siv dav hlau (AMS), xws li AMS 5596/5597.
Inconel 718 tshuaj muaj pes tsawg leeg
Kev pleev xim ntawm Inconel 718 ua raws li cov cai nruj raws li cov qauv zoo li AMS 5662 thiab AMS 5663. Qhov no ua kom nws ua tau zoo ib yam li txhua lub sijhawm.

Inconel 718 tensile zog
Inconel 718 daim hlau, cov ntawv, thiab cov coils feem ntau muaj lub zog tensile tshaj 1240 MPa (180 ksi) ntawm chav tsev kub, thiab tuav lawv lub zog txawm tias qhov kub siab (txog li 700 degree) vim lawv cov nag lossis daus hardening (hnub nyoog hardening) cov yam ntxwv. Lub zog sib txawv nyob ntawm qhov kev kho cua sov (kev daws teeb meem annealing + aging) thiab cov khoom tsim, nrog rau cov txiaj ntsig zoo xws li kwv yees li 965 MPa (140 ksi) hauv lub xeev annealed mus rau ntau dua 1379 MPa (200 ksi) tom qab ua haujlwm txias lossis kev laus kho.
Dab tsi yog qhov ceev ntawm Inconel 718?
Inconel 718 muaj qhov ntom ntom ntawm 8.19 g / cm³ (0.296 lb / in³), ua rau nws hnyav, siab -lub zog nickel alloy siv rau hauv kev thov aerospace thiab lub zog siv, nrog me ntsis txawv nyob ntawm kev ua, tab sis tsis tu ncua nyob ib ncig ntawm 8.2 g / cm³
Inconel 718 Poisson piv
Inconel 718 feem ntau muaj Poisson qhov piv ntawm 0.29 txog 0.30 ntawm chav tsev kub, txawm hais tias nws tuaj yeem sib txawv me ntsis nrog kev ua haujlwm (xws li 3D luam ntawv, qhov twg nws yuav yog 0.31-0.33) thiab txo qis me ntsis ntawm qhov kub siab dua, nrog rau qhov muaj nuj nqis zoo li 0.284 lossis 0.29 ua ib qho kev qhia txog nws cov ntaub ntawv super.
