Cob alt yog ib qho tseem ceeb alloying caij hauv maraging steel thiab ua haujlwm ntau yam. Cob alt yog siv los txo cov solubility txwv ntawm molybdenum thiab yog li nce qhov ntim feem ntawm Mo-nplua nuj precipitates (xws li Ni 3 Mo, Fe 2Mo.).
Yuav ua li cas yog lub ntsiab alloying hauv maraging steel?
Cob alt yog ib qho tseem ceeb alloying caij hauv maraging steel thiab ua haujlwm ntau yam. Cob alt yog siv los txo cov solubility txwv ntawm molybdenum thiab yog li nce qhov ntim feem ntawm Mo-nplua nuj precipitates (xws li Ni 3 Mo, Fe 2Mo.).
Yog maraging steel stainless?
Maraging stainless hlau (MSS) yogchav kawm ntawm lub zog siab stainless hlau nrog kev ua tau zoo tshaj plaws suav nrog lub zog siab, superior corrosion kuj thiab zoo weldability, thiab lwm yam. [1, 2], 3, 4, 5].
Dab tsi yog cov khoom ntawm maraging steel?
Khoom ntawm maraging steels
- High yield zog thiab qhov kawg tensile zog.
- High toughness.
- High ductility.
- High impact strength.
- High nkees zog.
- Kev ua haujlwm.
- High resistance to crack propagation.
- weldability.
Dab tsi yog qhov hardness ntawm maraging steel?
Maraging alloys yog qhov tseem ceeb tsis muaj cov pa roj carbon, qhov chaw tiv thaiv tsis tas yuav tsum tau thaum lub sij hawm annealing lossis aging. Cov khoom yog muab nyob rau hauv cov tshuaj annealed mob nrog ib tug hardness ntawm 30/35 Rc.

Nyob hauv lub lauj kaub hu lub lauj kaub dub lub ntsiab lus?
Cov lus no, uas tsim cov khoom siv hauv chav ua noj kom ua rau lub ntsiab lus ntawm kev siab phem, txhais tau tias "raug thuam ib tus neeg rau qhov txhaum koj kuj muaj" Per WiseGeek, cov kab lus rov qab mus rau thaum ntxov 1600s, thaum feem ntau lub lauj kaub thiab lub lauj kaub tau tsim los ntawm cov hlau cam, cov khoom uas tau txais cov pa luam yeeb dub thaum cua sov … lub ntsiab lus ntawm lub lauj kaub hu ua lub hwj dub yog dab tsi?
Qhov twg ntawm cov ntsiab lus alloying hauv qab no yog deoxidizers?
Muaj zog oxide-forming ntsiab, txhuas, silicon, thiab manganeseyog cov deoxidizers feem ntau siv hauv cov hlau tsim . Deoxidizer siv rau dab tsi? A deoxidizer yog ib qho chaw siv hauv cov tshuaj tiv thaiv kom tshem tawm cov pa oxygenCov khoom no muaj ib lossis ntau lub ntsiab lus uas yog scavengers rau oxygen txo qhov muaj cov pa yaj hauv cov hlau molten.
Nyob rau hauv cov ntsiab lus dav dav yog dab tsi yog lub hom phiaj ntawm lub txee?
A counterstain, xws li cov dej tsis muaj zog soluble safranin, yog ntxiv rau cov qauv, staining nws liab. Txij li thaum cov safranin yog sib dua li siv lead ua violet, nws tsis cuam tshuam cov xim ntshav hauv Gram zoo hlwb . Lub hom phiaj ntawm lub txee yog dab tsi?
Nyob rau hauv cov ntsiab lus ntawm iot yog dab tsi lub ntsiab lus ntawm ubiquitous?
