Cov ntaub ntawv hlau, raws li chav kawm ntawm cov ntaub ntawv nrog cov khoom siv hlau, xws li siv hlau, xws li siv hlau ua kom dav, suav nrog kev tsim kho rau kev tsim khoom siv ntau yam. Lawv tau siv dav hauv ntau thaj teb, los ntawm kev tsim kho rau kev tsim tshuab, txhua qhov tseem ceeb ntawm cov ntaub ntawv hlau.
I. Kev Sib Tw Ntawm Cov Ntaub Ntawv Hlau
Raws li lawv tus cwj pwm thiab siv, cov ntaub ntawv hlau feem ntau muab faib ua cov khoom siv hluav taws xob uas tsis muaj hlau thiab cov khoom siv hlau tshwj xeeb. Cov hlau ferrous, feem ntau yog raws li cov hlau, suav nrog cov hlau muaj kev muaj lag luam, cov hlau thiab ntau hom hlau hlau, stainless hlau thiab li ntawd. Cov hlau uas tsis muaj hlau, ntawm qhov tod tes, xa mus rau txhua cov hlau thiab cov alloys tsuas yog hlau, xws li cov hlau teeb, cov hlau hnyav thiab hlau. Cov ntaub ntawv tshwj xeeb hlau yog cov khoom siv hlau ntau, xws li cov ntaub ntawv hlau amorphous, cov khoom siv hlau tshwj xeeb thiab hlau sib xyaw.
Thib ob, kev ua haujlwm ntawm cov ntaub ntawv hlau
Kev ua yeeb yam ntawm cov ntaub ntawv hlau feem ntau muab faib ua ob pawg ntawm cov txheej txheem kev ua tau zoo thiab kev ua tau zoo. Cov txheej txheem kev ua tau zoo yog kev txhawj xeeb txog kev ua haujlwm ntawm cov ntaub ntawv hlau hauv kev tsim khoom, xws li kev ua haujlwm cam khwb, Weldability kev ua haujlwm. Kev siv kev ua tau zoo yog hais txog qhov tseeb ntawm kev siv, cov ntaub ntawv hlau qhia, nws yog qhov tshwj xeeb, nws txiav txim siab kom tiv thaiv ntau yam kev puas tsuaj thaum muaj peev xwm tiv thaiv kev puas tsuaj.
Thib peb, qaug zog tsis muaj zog ntawm cov ntaub ntawv hlau
Qaug zog ntawm cov khoom siv hlau yog qhov teeb meem ntau thiab txaus ntshai hauv engineering. Ntau qhov chaw hauv lub luag haujlwm ntawm lwm lub nra, txawm tias qib kev ntxhov siab yog qis dua ntawm cov khoom siv, tom qab lub sijhawm ntev kuj tseem tshwm sim tam sim ntawd Bracture. Cov yam ntxwv ntawm kev ua kom muaj zog sib cais yog suav nrog kev siv hluav taws xob, lub sijhawm ntev ntawm kev ua, qhov kev hloov pauv ntawm pob txha, thiab tus brittleness ntawm qhov chaw lov. Qoj kev tshwm sim tuaj yeem faib rau ntau hom xws li kev ua kom mob siab ntau dua, nkees nkees, ua kom qaug zog, kev nkees nkees thiab kev nkees nkees.
Hauv cov ntsiab lus, xim hlau cov ntaub ntawv, raws li ib qho tseem ceeb ntawm kev tsim kev lag luam thiab lub neej txhua hnub, muaj ntau yam khoom thiab kev faib tawm thiab siv dav. To taub cov ntaub ntawv hlau, tshwj xeeb tshaj yog lawv qhov tsis txaus siab, yog qhov tseem ceeb kom ntseeg tau kev nyab xeeb thiab txhim kho txoj haujlwm lub neej.
