Inconel Alloys: Ib Daim Ntawv Qhia Tag Nrho

Cov cim lag luam Inconel tau sau npe hauv 1932 los ntawm International Nickel Company ntawm Delaware thiab New York hauv Asmeskas Inconel® alloys ua lub luag haujlwm tseem ceeb hauv kev tsim lub tshuab Whittle Jet thaum ntxov 1940s, ua tsaug rau kev tshawb fawb los ntawm Henry Wiggin & Co hauv Hereford, England. Cov cim lag luam Inconel tom qab tau txais hauv 1998 los ntawm Special Metals Corporation, ntxiv rau kev nce qib ntawm cov hlau tseem ceeb.

Inconel alloys xa mus rau tsev neeg ntawm austenitic alloys ntawm npib tsib xee thiab chrome, cov no yog cov cim kev lag luam siab -lub zog superalloys nrog tshwj xeeb corrosion kuj thiab cov khoom ua haujlwm kub. Inconel yog npib tsib xee / chromium, hlau / hlau superalloy nrog ntxiv ntawm lwm yam xws li molybdenum, cobalt, tantalum, titanium, thiab tooj liab. Inconel feem ntau yog thawj qhov kev xaiv rau kev thov hauv geothermal, nuclear, aerospace, shipbuilding, thiab chemical processing, qhov twg cov khoom raug kub, siab los yog mechanical loads.

Inconel® alloys yog oxidation thiab corrosion resistant. Thaum qhov kub thiab txias, Inconel® tsim cov txheej txheem passivation ruaj khov uas tiv thaiv qhov chaw los ntawm kev tawm tsam ntxiv. Inconel® khaws lub zog ntawm qhov kub thiab txias, txaus nyiam rau siab - cov ntawv thov kub qhov twg txhuas thiab hlau yuav ua rau nkag mus. Inconel lub siab - qhov kub thiab txias yog tsim los ntawm cov khoom siv ntxiv dag zog ** los yog nag lossis daus hardening ***, nyob ntawm cov hlau.

* Ib qho superalloy yog ib qho hlau uas muaj peev xwm ua haujlwm ntawm ib feem ntawm nws qhov melting point. Cov yam ntxwv tseem ceeb ntawm superalloy muaj xws li txhua yam muaj zog, corrosion thiab oxidation tsis kam, thermal creep deformation kuj thiab nto stability.

** Solid Solution Strengthening yog ib txoj hauv kev uas cuam tshuam cov kuab tshuaj mus rau hauv cov kuab tshuaj los ua ib qho kev daws teeb meem, uas cuam tshuam kev txav mus los hauv cov hlau, yog li ua kom muaj zog.

*** Precipitation Hardening (tseem hu ua lub hnub nyoog hardening lossis particle hardening) yog cov txheej txheem kev kho cua sov uas tsis tshua muaj cov khoom me me kis tau zoo sib xws hauv cov khoom qub kom nws lub zog thiab hardness.
