Feem ntau cov check hlau: yuav ua li cas nws

Los ntawm thaum yau, peb paub hais tias cov feem ntau check hlau - nws yog hlau. Tag nrho cov hlau peb nyob qib qub nws.

Txiv neej hlau, hlau poj niam, steel cim. Hais cov nqe lus, peb txhais li cas zoo kawg lub dag lub zog, lub zog, hardness.

Rau ib ntev lub sij hawm nyob rau hauv qhov siv thiab ua ntaj los sis phom thiab puag cov ntaub ntawv uas yog hlau. Tab sis steel - tsis hlau. Hais dua, nws tsis yog heev ntshiab hlau. Qhov no hlau compound nrog carbon, nyob rau tam sim no thiab lwm cov hlau additives. Thov additives steel alloyed, i.e. hloov nws cov khoom. Tom qab ntawd, nws tiav. Steelmaking - yog ib tug science.

Feem ntau cov check hlau tau raws li qhov kev taw qhia rau hauv uas tsim nyog steel ligatures. Qhov no tej zaum yuav chromium, uas hniav hlau hardness thiab tshav kub tsis kam, npib tsib xee, steel siab ruaj thiab elastic, etc.

Rau ib txhia cov khoom lub steel pib tshem txhuas. Raws li lub sij hawm mus rau, cov kev ceev zog. Kuv yuav tsis sawv ntsug thiab txhuas. Kuv yuav tsum tau tig mus rau titanium.

Yog, vim hais tias cov titanium - lub feem ntau check hlau. Yuav kom impart siab zog yam ntxwv ntawm steel nws pib ntxiv titanium.

Nws twb qhib nyob rau hauv lub XVIII caug xyoo. Vim lub fragility ntawm nws siv yog tsis yooj yim sua. Thaum lub sij hawm, tus tau txais ntshiab titanium, engineers thiab designers yog xav nws cov high tej lub dag lub zog, uas tsis muaj kev ceev, ua hauj corrosion thiab siab kub. Nws lub dag lub zog tshaj lub dag lub zog ntawm cov hlau ib ob peb lub sij hawm.

Engineers pib mus ntxiv titanium rau cov hlau. Cov tshwm sim yog lub feem ntau check hlau, uas pom daim ntawv thov nyob rau hauv ultra kub ib puag ncig. Nyob rau ntawm lub sij hawm lawv tsis muaj lwm yam alloy.

Yog hais tias peb xav txog tej yam ib tug dav hlau, uas yoov peb lub sij hawm sai tshaj li cov kev ceev ntawm lub suab yuav tuaj raws li ib tug sov so hlau sheathing. Sheet hlau daim tawv nqaij ntawm lub aircraft nyob rau hauv xws tej yam kev mob yog rhuab mus + 3000C.

Niaj hnub no, titanium yog siv indefinitely nyob rau hauv tag nrho cov cheeb tsam ntawm kev ntau lawm. Qhov no tshuaj, chaw ua dav hlua, raug ships.

Kom meej meej peb yuav hais tias titanium yuav tau tsiv mus nyob rau lub nyob ze yav tom ntej.

Zaum ntawm lub tebchaws United States, nyob rau hauv lub chaw soj nstuam ntawm lub University of Texas nyob rau hauv Austin, qhib hom kev ntau lawm ntawm lub thinnest thiab feem ntau check cov ntaub ntawv uas nyob rau hauv lub ntiaj teb no. Peb hu ua nws - graphene.

Xav txog tej yam kev carbon phaj nrog ib tug tuab sib npaug zos rau cov thickness ntawm ib tug atom. Tab sis xws li ib tug phaj yog muaj zog pob zeb diamond thiab ib puas lub sij hawm zoo hau hluav taws xob tam sim no tshaj li lub computer chips ntawm silicon.

Graphene - cov ntaub ntawv uas rau khoom. Nws yuav sai sai no tawm hauv lub lab thiab yuav los rightfully muab nws qhov chaw ntawm cov feem ntau check cov ntaub ntawv uas ntawm lub ntug.

Txawm tsis yooj yim sua xav txog tej yam uas ib tug ob peb grams ntawm graphene yuav txaus mus them rau cov teb rau qhov kev ua si ntawm football. Ntawm no yog ib tug hlau. Kav ntawm no cov ntaub ntawv uas yuav pw ntawm tes tsis muaj kev siv ntawm hoisting mechanisms.

Graphene, zoo li ib tug pob zeb diamond - nws yog dawb huv carbon. Nws yooj yog amazing. Tej ntaub ntawv uas yog yooj yim khoov duav, txig tsim thiab zoo dov li.

Rau nws twb pib mus rau saib ze ze manufacturers uas kov cov ntxaij vab tshaus, solar hlwb, lub zog cia li, xovtooj ntawm tes, thiab, thaum kawg, lub superhighways ntawm computer chips.
