1. Tsawg Txheej Txheem Thaum Quenching
Quenching (sai sai los ntawm Ausenitizing Kub) tsis tsim cov khoom tseem ceeb (cov theem nyuaj nyob rau hauv high - alloy class). Hloov chaw, nws feem ntau cov ntawv nplua ferrite thiab hlaws, zoo ib yam li ib txwm tab sis muaj lub zog siab dua tab sis kom nrawm dua.
Lub zog nce yog tsawg kawg (tensile lub zog nce qib los ntawm ≤5% piv rau qhov normalization) thiab tsis muaj txiaj ntsig zoo rau cov ntawv thov.
2. Tempering tom qab quenching: marginal txhim kho
Tshem tawm cov kev ntxhov siab me me los ntawm quenching, kev txhim kho me ntsis nruj (charpy cuam tshuam lub zog nce los ntawm 5-10%).
Tej zaum yuav txo qhov nyuaj me ntsis tau txais los ntawm quenching, tab sis txij li quenching nws tus kheej tsis loj heev steel, lub nyhuv tag nrho yog negligible.
3. Tseem Ceeb Digbacks
Txo corrosion tsis kam: Kev kho kom sov li txawv txawv (piv txwv li, overheating thaum quenching) tuaj yeem cuam tshuam rau kev sib faib ntawm CU, thiab NI, puas qhov kev tsim tawm ntawm Oxide zaj duab xis tseem ceeb rau huab cua ua yeeb yam.
Nce brittleness pheej hmoo: Quenching nrawm dua tuaj yeem ua rau muaj kev ntxhov siab ua kom sov, ua rau microcacks hauv cov nplooj tuab, tshwj xeeb yog npau taws tsis txaus.
Kev Lag Luam Tsis Muaj Peev Xwm: Quenching thiab tempering yuav tsum muaj lub zog ntau dua thiab cov txheej txheem stricter uas tau muaj nuj nqi siv rau kev siv hluav taws xob (cov txheej txheem kev sib xyaw ua ke).
4. Qhov Kev Xaiv Kom Zoo: Li Qub
Refe nplej zom thiab homogenizes microstructure, ntsuas lub zog thiab tawv.
Khaws cia cov kev faib tawm ntawm cov khoom sib txuam ntawm cov ntsiab lus ntawm cov ntsiab lus, ua kom tiav qhov tsim nyog tsim ntawm kev tiv thaiv Patina.
Puas muaj nqi ntau dua -}} Zoo thiab txhim khu kev qha rau cov ntawv thov kev tsim qauv.
