Cov txheej txheem ua haujlwm kub kub yog plasticically deformed saum lawv qhov ntsuas kub recrystallization. Ua siab tshaj qhov kub ntawm recrystallization tso cai rau cov khoom siv recrystallize thaum deformation. … Ntau yam kev ua haujlwm, suav nrog dov, forging, extrusion, thiab kos duab, tuaj yeem ua tiav nrog cov hlau kub.
Qhov twg ntawm cov txheej txheem kub hauv qab no ua haujlwm?
Daim ntawv thov ntawm cov hlau kub ua haujlwm suav nrog kub dov, forging, extrusion thiab kub kos duab. Cov khoom siv carbon steel thiab stainless hlau yog dov los ua daim hlau nyias thiab extruded los tsim cov duab uas xav tau. Kev ua haujlwm kub yog siv los hloov cov hlau thiab hlau tsis muaj kev puas tsuaj thiab siv zog ntau dhau.
Kev ua haujlwm kub thiab txias ua haujlwm yog dab tsi?
Yas deformation uas yog ua nyob rau hauv ib cheeb tsam kub thiab nyob rau ib lub sij hawm luv luv xws li cov strain hardening yog tsis relieved yog hu ua txias ua hauj lwm. … Kub ua hauj lwm yog hais txog cov txheej txheem uas hlau deformed saum lawv recrystallization kubthiab strain hardening tsis tshwm sim.
Puas yog khoov cov txheej txheem ua haujlwm kub?
Cov txheej txheem zoo li no tau sib piv nrog cov txheej txheem ua haujlwm kub xws li kub dov, forging, vuam, thiab lwm yam. Cov txheej txheem txias txias feem ntau muab faib ua plaub pawg loj: nyem, khoov, kos duab, thiab shearing. Lawv feem ntau muaj qhov zoo ntawm kev ua kom yooj yim dua li kev ua haujlwm kub.
txheej txheem ua haujlwm txias yog dab tsi?
Cojkev ua haujlwm yog txheej txheem ntawm cov hlau ntxiv los ntawm cov yas deformation. Qhov no yog ua tau los ntawm kev txav mus los uas tau tsim nyob rau hauv cov khoom siv lead ua qauv. Qhov no yog cov txheej txheem uas feem ntau siv rau hauv cov hlau uas tsis yog nkig uas muaj cov ntsiab lus melting zoo kawg nkaus.
