    Ubuchwepheshe obuyinhloko be-Berryllium Copper (Ukwelashwa kokushisa)

    Ukwelashwa kokushisa kuyinqubo ebaluleke kakhulu yalolu hlelo lwe-alloy. Nakuba wonke ama-alloys ethusi enziwa lukhuni ngokusebenza okubandayo, ithusi le-beryllium lihlukile ekubeni lukhuni ngokwelashwa okushisayo okuphansi kwezinga lokushisa. Kuhilela izinyathelo ezimbili eziyisisekelo. Eyokuqala ibizwa ngokuthi i-annealing yesixazululo kanti eyesibili, imvula noma ukuqina kweminyaka.

    Isixazululo Anealing

    Okwengxubevange ejwayelekile CuBe1.9 (1.8- 2%) ingxubevange ifudunyezwa phakathi kuka-720°C no-860°C. Kuleli qophelo i-beryllium equkethwe empeleni "incibilika" ku-matrix yethusi (isigaba se-alpha). Ngokucisha ngokushesha ekamelweni lokushisa lesi sakhiwo sesisombululo esiqinile siyagcinwa. Izinto ezikulesi sigaba zithambile kakhulu futhi ziyi-ductile futhi zingabanda kalula ngokudweba, ukwenza ukugoqa, noma isihloko esibandayo. Umsebenzi wokukhipha isixazululo uyingxenye yenqubo emshinini wokugaya futhi ngokuvamile awusetshenziswa ikhasimende. Izinga lokushisa, isikhathi ezingeni lokushisa, izinga lokucisha, usayizi wokusanhlamvu, nobulukhuni konke kuyimingcele ebaluleke kakhulu futhi kulawulwa ngokuqinile yi-TANKII.

    Ukuqina kweminyaka

    Ukuqina kweminyaka kuthuthukisa kakhulu amandla wento. Lokhu kusabela ngokuvamile kwenziwa emazingeni okushisa aphakathi kuka-260°C no-540°C kuye ngengxubevange nezici ezifiswayo. Lo mjikelezo ubangela i-beryllium encibilikisiwe ukuthi ihle njengesigaba esicebile se-beryllium (i-gamma) ku-matrix kanye nasemingceleni yokusanhlamvu. Ukwakheka kwalesi mvula esidala ukwanda okukhulu kwamandla ezinto ezibonakalayo. Izinga lezakhiwo zemishini ezifinyelelwe linqunywa izinga lokushisa kanye nesikhathi ekushiseni. Kufanele kuqashelwe ukuthi ithusi le-beryllium alinazo izici zokuguga zegumbi lokushisa.
