1. Cov khoom siv yog 800HT incoloy?

Incoloy 800ht yog ib npib tsib xee {{}} pread {}}}}}}}} kev daws teeb meem zog superalalloy. Nws nominal tshuaj muaj pes tsawg leeg (los ntawm qhov hnyav) ua rau cov qauv kev lag luam (piv txwv li, ASTM B409, ASME SB-409) thiab feem ntau suav nrog cov ntsiab lus hauv qab no:

Nickel (NI):30.0% {- 35.0% (kev sib txuam ua ke, txhim kho corrosion tsis kam thiab siab- kub ruaj khov)

Chromium (CR):19.0% {{- 23.0% (txhim kho oxidation thiab carburization tsis kam ntawm siab kub)

Hlau (FE):Tshuav nyiaj (cov hlau hauv paus, muab cov qauv kev ncaj ncees)

Cov pa roj carbon (c):0.06% - 0.10}% (ntau dua li cov qauv txheej txheem 800, boosts

Aluminium (Al):0.15% {{{- 0.60% (AIDS hauv kev sib sau cov roj oxide)

Titanium (ti):0.15% {{{- 0.60% (ua haujlwm nrog al los txhim kho oxidation tsis kam thiab ruaj khov lub almoy qauv)

Manganese (MN):Qhov siab tshaj 1.50% (txhim kho kev ductility thiab kev ua haujlwm)

Silicon (si):Qhov siab tshaj plaws 1.00% (Pab cov roj oxide txheej txheej)

Tooj liab (Cu):Qhov siab tshaj 0.75% (kab cim caij nyoog, txo qis ntawm cov chaw tseem ceeb)

Sulphur (s):Qhov siab tshaj plaws 0.015% (tswj kom tsis txhob tsis txhob brittleness)

2. Dab tsi yog cov txiaj ntsig lub zog ntawm incoloy 800ht?

Cov txiaj ntsig lub zog ntawm incoloy 800ht sib txawv me ntsis raws liKev Kho Cua Sov Lub Xeev(piv txwv li, annealed, tov - annealed) thiabsim ntsuas kub, raws li kev kub siab tuaj yeem txo cov txiaj ntsig zoo lub zog. Hauv qab no yog qhov tseem ceeb (ib astm b409 thiab ASME BPVC Ntu II Cov Qauv) rau qhov kev tshaj tawm cov lus qhia:

Chav nyob (20℃/ 68℃f):Yam tsawg kawg 275 MPa (40,000 PSI); Tus nqi raug nyob ib ncig ntawm 310 MPA (45,000 PSI).

Nce qhov kub (piv txwv):

Thaum 500℃(932 Qib F): ~ 24 MPa (34,800 psi)

Ntawm 700℃(1,292℃f): ~ 170 mpa (24,650 psi)

Thaum 900℃(1,652 Qib F): ~ 85 MPa (12,330 PSI)

Nco tseg: paib lub zog ntawm no yog hais txog qhov0.2% offset muab lub zog(Qhov kev ntxhov siab uas cov ntaub ntawv nthuav qhia kev deformation nyob rau hauv 0.2%), kev lag luam txheem rau cov ntaub ntawv hlau.

3. Dab tsi yog lub tensile lub zog ntawm incoloy 800ht?

Zoo li paib lub zog, tensile lub zog (kawg tensile muaj zog, UTS

Chav nyob (20℃/ 68℃f):Yam tsawg kawg 550 mpa (79,800 psi); Tus nqi raug nyob ib ncig ntawm 600 mpa (87,000 psi).

Nce qhov kub (piv txwv):

Ntawm 500℃(932 Qib F): ~ 480 MPa (69,600 PSI)

Ntawm 700℃(1,292℃f): ~ 340 MPa (49,300 psi)

Thaum 900℃(1,652 Qib F): ~ 150 MPA (21,750 psi)

Lub zog tensile sawv cev rau qhov kev ntxhov siab tshaj plaws uas cov khoom siv tuaj yeem tiv thaiv ua ntej pob txha ua kom qis hauv qab.

4. Dab tsi yog lub hardness ntawm incoloy 800ht?

Hardness ntawm incoloy 800ht yog feem ntau ntsuas nyob rau hauv lubAnnealed mob(Feem ntau cov khoom siv hauv xeev) siv cov nplai tsim nyog rau cov muag muag {{0} {1}- xob muaj zog alloys. Cov nuj nqis raug (Per ASTM B409) yog:

Brinell Hardness (HB):Qhov siab tshaj plaws xyoo 190 HB (kuaj nrog 10 hli inch steel pob thiab 3,000 kg load).

Rockwell Hardness (HR):

Rockwell B (HRB): Ntau tshaj plaws 90 teev (ib txwm muaj (

Rockwell C (HRC): Tsis yog ib txwm teev, raws li alloy txoj kev tawv tawv yog tsawg rau qhov tseeb HRC ntsuas (HRC tseem ceeb yuav nyob ze 0).

Hardness yuav nce me ntsis nrog kev ua haujlwm txias (piv txwv li cov ntaub pua chaw txias (uas tsis tau siv rau hauv qhov txias {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} anneal temperature} environ} environ}} anneal temperature} environ} environ} 4}}} anneal temperature} environ} environ} environ }}}}} anneal temperature} material} environ} environ} 4} environ} 4} environ} environ} 4} environ} environ} 4} environ} 4} environ}}} anneal temperatureល).
