Cov ntsiab lus tseem ceeb: Taw qhia ntawm cov rooj tog hlau iav. Hlau iav rooj tog yog ib qho tseem ceeb ntawm cov rooj tog zaum niaj hnub. Raws li lub npe qhia, cov rooj tog iav hlau yog rooj tog uas sib xyaw hlau thiab iav. Hlau iav rooj tog yog hlub los ntawm ntau thiab ntau tus neeg rau nws txoj kev yooj yim thiab yooj yim. Cia ua raws li tus editor ntawm "Xianghe Furniture City" hauv online khw kom paub txog kev qhia txog cov rooj tog hlau iav! Kev taw qhia txog hlau iav rooj tog.

Hlau iav rooj tog yog ib qho tseem ceeb ntawm cov rooj tog zaum niaj hnub. Raws li lub npe qhia, cov rooj tog iav hlau yog rooj tog uas sib xyaw hlau thiab iav. Hlau iav rooj tog yog hlub los ntawm ntau thiab ntau tus neeg rau nws txoj kev yooj yim thiab yooj yim. Cia ua raws li tus editor ntawm "Xianghe Furniture City" hauv online khw kom paub txog kev qhia txog cov rooj tog hlau iav! Hlau iav, tseem hu ua amorphous alloy, muaj ob qho tib si zoo ntawm cov hlau thiab iav thiab kov yeej lawv cov kev tsis zoo hauv kev siv cov ntaub ntawv rooj tog. Zoo li iav, nws yog nkig thiab tsis muaj ductility.

Lub zog ntawm cov iav hlau yog siab dua li ntawm cov hlau, lub hardness yog siab dua li ntawm high-hardness tool steel, thiab nws muaj qee yam toughness thiab rigidity. Yog li ntawd, tib neeg qhuas cov iav hlau ua "tus huab tais ntawm iav" uas yog "tsis tawg thiab tsis tawg". Thaum neeg feem coob xav txog iav, lub tswv yim ntawm iav panels sai sai rau hauv peb lub siab. Tab sis nyob rau hauv qee qhov xwm txheej, hlau kuj tuaj yeem ua rau hauv iav, piv txwv li: lub khob no tuaj yeem siv los ua cov khoom siv zoo tshaj plaws rau lub hwj chim transformers thiab golf clubs.

Port Baltimore, Johns Hopkins University tus kws tshawb fawb Todd C. Hufnagel tab tom ua haujlwm los tsim cov iav hlau uas muaj zog heev, elastic thiab sib nqus. Hufnagel xav kom nkag siab tias thaum lub iav hlau yog tsim, metallographic transformations tshwm sim thaum molten hlau txias rau cov khib nyiab. Rau cov kws tshawb fawb, iav yog cov khoom siv uas tuaj yeem ua kom txias los ntawm cov kua mus rau cov khoom tsis muaj crystallization.

Feem ntau cov hlau crystallize thaum lawv txias, nrog cov atoms teem rau hauv ib qho qauv hu ua lattice. Yog tias crystallization tsis tshwm sim thiab cov atoms nyob tsis tu ncua, cov iav hlau yog tsim. Tsis zoo li cov iav panes, cov iav xim hlau tsis yog pob tshab lossis nkig, thiab lawv cov qauv tsis tshua muaj atomic muab lawv cov khoom tshwj xeeb thiab cov khoom sib nqus.

Ordinary hlau yog yooj yim deformed los yog khoov vim tsis xws luag nyob rau hauv lawv cov lattice mus tas li poob lawv cov duab. Nyob rau hauv sib piv, nws yog xim hlau iav springs rov qab mus rau nws cov qub duab yooj yim dua tom qab deformation. Qhov tsis muaj crystallinity ua rau cov iav iav ntawm cov hlau molten hlau yog cov khoom siv hlau nplaum zoo.

Cov tsos ntawm cov iav hlau tuaj yeem taug qab rov qab mus rau xyoo 1930, thaum Kramer thawj zaug qhia txog kev npaj cov iav hlau los ntawm vapor deposition. Xyoo 1950, metallurgists tau kawm tias los ntawm kev sib xyaw ntawm qee cov hlau, xws li npib tsib xee thiab zirconium, Xyoo 1960, Klement thiab Duwez ntawm California Institute of Technology siv quenching technology los npaj Au75Si25 hlau iav. Thaum cov txheej nyias nyias ntawm cov alloys txias ntawm tus nqi ntawm ib puas degrees Celsius ib ob, lawv tsim cov iav hlau. Tab sis vim yog qhov yuav tsum tau ua kom txias ceev, lawv tsuas tuaj yeem ua rau nyias nyias, cov xov hlau lossis cov hmoov.

Tsis ntev los no, cov kws tshawb fawb tau sib xyaw cov ntsiab lus ntawm plaub mus rau tsib lub atoms ntawm ntau qhov sib txawv los tsim ntau hom iav hlau xws li strips. Hloov cov atomic loj tso cai rau nws sib tov los ua iav thiab yog li ua tawv. Ib qho ntawm kev siv cov alloys tshiab no yog siv hauv kev lag luam los ua golf taub hau.
