Cov ntsiab lus tseem ceeb ntawm beryllium tooj liab (Kev Kho Cua Sov)
Kev kho cua sov yog cov txheej txheem tseem ceeb tshaj plaws rau cov txheej txheem alloy. Thaum txhua lub taub hau loj heev yog qhov nyuaj los ntawm kev ua haujlwm txias, tooj liab yog qhov tshwj xeeb los ntawm kev kho kom sov yooj yim los ntawm qhov ntsuas kub yooj yim. Nws cuam tshuam nrog ob theem pib. Qhov thib ib yog hu ua kev daws annaling thiab thib ob, nag lossis daus lossis hnub nyoog tawv.
Kev daws Annealing
Rau cov neeg raug alloy lub voos sab nrauv1.9 (1.8- 2%) lub alloy yog rhaub ntawm 720 ° C thiab 860 ° C. Txij ntawm no muaj beryllium yog qhov tseem ceeb "yaj" hauv lub tooj liab matrix (alphas theem). Los ntawm sai sai quenching mus rau chav tsev kub cov qauv kev daws teeb meem tau khaws tseg. Cov khoom siv nyob rau theem no yog cov muag muag heev thiab canile thiab tuaj yeem yooj yim txias ua haujlwm los ntawm kev kos duab, kev dov, lossis cov taub hau txias. Kev daws teeb meem kev daws teeb meem yog ib feem ntawm cov txheej txheem ntawm lub zeb thiab tsis yog ib txwm siv los ntawm cov qhua tuaj noj mov. Qhov kub, lub sijhawm ntawm qhov kub thiab qhov loj me, thiab lub hardness ntau yog txhua tus heev tseem ceeb heev thiab muaj nruj nreem los ntawm tankii.
Hnub nyoog Hardening
Lub hnub nyoog harvening ntau dua ua rau cov khoom siv lub zog. Qhov tshuaj tiv thaiv no feem ntau nqa tawm ntawm qhov kub ntawm 260 ° C thiab 540 ° C nyob ntawm cov yam ntxwv ntawm cov yam ntxwv. Lub voj voog no ua rau muaj kev ua kom yaj ua ntej ua ntej los ua cov khoom noj khoom haus beryllass nplua nuj (gamas) theem hauv cov kab sib luag. Nws yog qhov tsim ntawm cov prepipate no uas ua rau muaj cov khoom muaj zog loj. Cov qib ntawm cov khoom siv neeg siv cov khoom siv tau txiav txim siab los ntawm qhov kub thiab sijhawm kub thiab sijhawm. Nws yuav tsum tau lees paub tias BerylLlium tooj liab tsis muaj chav sov kev laus laus.
