Kev taw qhia ntawm lub txaj chaw tsim khoom ntawm hlau iav rooj tog

Cov ntsiab lus ntawm hlau iav rooj tog yog qhia. Hlau iav rooj tog yog ib qho tseem ceeb ntawm cov rooj tog zaum niaj hnub, raws li lub npe implies, hlau iav rooj tog yog kev sib txuas ntawm hlau thiab iav rooj tog, hlau iav rooj tog nrog nws cov ntsiab lus thiab yooj yim nta yog nrov nrog ntau thiab ntau tus neeg. Ua raws li 'xianghe rooj tog nroog' online khw hauv qab me me ua ke los kawm 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 implies, hlau iav rooj tog yog kev sib txuas ntawm hlau thiab iav rooj tog, hlau iav rooj tog nrog nws cov ntsiab lus thiab yooj yim nta yog nrov nrog ntau thiab ntau tus neeg. Ua raws li 'xianghe rooj tog nroog' online khw hauv qab me me ua ke los kawm txog kev qhia txog cov rooj tog hlau iav! Cov iav hlau kuj tseem hu ua amorphous alloy, hauv cov ntaub ntawv siv rooj tog, nws muaj qhov zoo ntawm cov hlau thiab iav, thiab kov yeej lawv qhov tsis zoo. Xws li iav yog tawg yooj yim, tsis muaj malleability. Lub zog muaj zog siab dua li cov hlau, hardness ntawm cov iav hlau ntau dua li cov cuab yeej nyuaj steel, thiab muaj qee qhov toughness thiab rigidity, yog li, cov neeg qhuas cov iav hlau li 'tsis txhob khob tsis tawg,' tus huab tais ntawm ' iav'. Thaum neeg feem coob xav txog iav, iav sai sai dhia lub tswv yim ntawm peb lub siab. Tab sis nyob rau hauv qee qhov xwm txheej, cov iav hlau tuaj yeem ua rau nws, piv txwv li: hom iav no tuaj yeem siv los ua cov khoom siv zoo tshaj plaws ntawm lub hwj chim transformer thiab golf clubs. Johns Hopkins (chaw nres nkoj ntawm Baltimore, 约翰霍普金斯大学) Ib tug kws tshawb fawb ntawm University of Todd C. Hufnagel tab tom ua haujlwm ntawm kev tsim cov super, elastic thiab sib nqus cov yam ntxwv ntawm cov iav hlau. Hufnagel xav paub, thaum lub iav hlau tsim, tshwm sim thaum melting hlau txias rau hauv cov khoom metallographic transformation. Rau cov kws tshawb fawb, iav tuaj yeem ua kom txias los ntawm cov kua rau cov khoom thiab tsis muaj cov ntaub ntawv crystalline. Feem ntau ntawm cov hlau txias crystallization, cov kev cai ntawm atoms teem nyob rau hauv ib daim ntawv hu ua siv lead ua lattice. Yog hais tias koj tsis tshwm sim crystallization thiab atomic kev npaj yog tsis xwm yeem, tseem ua hlau iav. Tsis nyiam iav, hlau, iav tsis pob tshab lossis tsis nkig, lawv cov qauv atomic tsawg heev kom lawv muaj cov khoom tshwj xeeb thiab cov khoom sib nqus. Ordinary hlau vim lawv cov lattice tsis xws luag thiab yooj yim rau bending deformation los yog ua rau mus tas li poob ntawm daim ntawv. Nyob rau hauv sib piv, hlau iav tom qab deformation muaj feem yuav thaws rov qab mus rau nws tus qub zoo li qub. Tsis muaj cov khoom siv lead ua tsis zoo ua rau cov khoom qub molten hlau hlau iav siv cov khoom sib nqus zoo. Lub xub ntiag ntawm cov iav hlau tuaj yeem taug qab rov qab mus rau xyoo pua s, Kramer thawj zaug tshaj tawm cov roj tso tawm ntawm cov iav hlau, metallurgists hauv xyoo, kawm los ntawm kev sib xyaw nrog qee cov hlau - - Los qhia cov muaju, xws li npib tsib xee thiab zirconium, Klement ntawm California lub koom haum thev naus laus zis, thiab Duwez AuSi hlau iav yog npaj los ntawm quenching technology. Thaum ib txheej nyias ntawm alloy nyob rau hauv ib puas degrees rau ib tug thib ob tus nqi ntawm txias, lawv tsim metallic iav. Tab sis vim tias xav tau kom txias sai, lawv tsuas tuaj yeem ua rau hauv cov hlua nyias, hlau lossis hmoov. Tsis ntev los no, cov kws tshawb fawb los ntawm kev sib xyaw cov ntsiab lus ntawm lub atom, plaub lossis tsib qhov sib txawv los tsim xws li ntau yam hlau iav sawb. Hloov atomic loj ua rau nws sib tov los ua ib lub khob kom nruj dua. Hauv kev lag luam yog ib lub hom phiaj ntawm cov hlau tshiab no siv los ua lub taub hau golf
