Key Technology ya Beryllium Copper (Kutentha mankhwala)
Chithandizo cha kutentha ndi njira yofunika kwambiri pa dongosolo la alloy. Ngakhale kuti zitsulo zonse zamkuwa zimakhala zowumitsidwa ndi kuzizira, mkuwa wa beryllium ndi wapadera pokhala wouma chifukwa chosavuta kutentha kutentha. Zimaphatikizapo zinthu ziwiri zofunika kwambiri. Choyamba chimatchedwa njira yothetsera vutoli ndipo chachiwiri, mvula kapena kuuma kwa zaka.
Solution Annealing
Kwa aloyi wamba CuBe1.9 (1.8- 2%) aloyiyo imatenthedwa pakati pa 720 ° C ndi 860 ° C. Panthawiyi beryllium yomwe ili ndi "beryllium" imakhala "kusungunuka" mu matrix amkuwa (gawo la alpha). Mwa kuzimitsidwa mwachangu mpaka kutentha kwa chipinda cholimba ichi chimasungidwa. Zomwe zili panthawiyi ndizofewa kwambiri komanso zimakhala zofewa ndipo zimatha kuzizira mosavuta pojambula, kupanga kugudubuza, kapena mutu wozizira. Njira yothetsera annealing ndi gawo la njira yopangira mphero ndipo sagwiritsidwa ntchito ndi kasitomala. Kutentha, nthawi yotentha, kutentha, kukula kwa tirigu, ndi kuuma zonse ndizofunika kwambiri ndipo zimayendetsedwa mwamphamvu ndiTANKII.
Kuumitsa Zaka
Zaka kuumitsa kwambiri kumawonjezera mphamvu zakuthupi. Izi nthawi zambiri zimachitika pa kutentha kwapakati pa 260 ° C ndi 540 ° C kutengera aloyi ndi mawonekedwe omwe akufuna. Kuzungulira uku kumapangitsa kuti beryllium yosungunuka igwe ngati beryllium wolemera (gamma) gawo mu matrix komanso pamalire ambewu. Ndiko kupangidwa kwa mpweya uwu womwe umayambitsa kuwonjezeka kwakukulu kwa mphamvu zakuthupi. Mlingo wa zinthu zamakina zomwe zapezeka zimatsimikiziridwa ndi kutentha ndi nthawi yotentha. Tiyenera kuzindikira kuti mkuwa wa beryllium umakhala wopanda kutentha kwa kutentha.
