He tino maha ngā whakamahinga o te parahi beryllium hei whakapakeke i te wairewa. I muri i te otinga totoka me te maimoatanga tawhito, ka taea te kaha ki te 1250-1500MPa (1250-1500kg). Ko ōna āhuatanga maimoatanga wera: he pai te kirihou i muri i te maimoatanga otinga totoka, ā, ka taea te whakapēhia mā te mahi matao. Heoi, i muri i te maimoatanga tawhito, he tino pai te rohe pīngore, ā, ka pai ake hoki tōna pakeke me tōna kaha.
(1) Te rongoā i te parahi beryllium ki te otinga totoka
Ko te tikanga, ko te pāmahana whakamahana mō te tukatuka otinga kei waenga i te 780-820℃. Mō ngā rauemi e whakamahia ana hei wāhanga rapa, ka whakamahia te 760-780℃, hei ārai i te pānga o ngā kirikiri matotoru ki te kaha. Me tino whakahaere te ōritetanga o te pāmahana o te oumu maimoatanga otinga i roto i te ±5°C. Ko te wā pupuri ka taea te tatau ko te 1 hāora/25mm. Ina tukuna te parahi beryllium ki te maimoatanga whakamahana otinga totoka i te hau, i te hau whakahāngai rānei, ka hangaia he kiriata waikura ki runga i te mata. Ahakoa he iti noa te pānga ki ngā āhuatanga miihini i muri i te whakapakaritanga o te tawhito, ka pā ki te roa o te mahi o te pokepoke taputapu i te wā e mahi matao ana. Hei karo i te waikura, me whakamahana ki roto i te oumu korehau, i te pirau haukini rānei, i te hau kore mahi, i te hau whakaiti (pēnei i te hauwai, te hau hauhā, me ētahi atu) kia whiwhi ai i te pānga maimoatanga wera kanapa. Hei tāpiri, me aro ki te whakapoto i te wā whakawhiti (i te wā tinei) i te mea ka taea, ki te kore ka pāngia ngā āhuatanga miihini i muri i te koroheketanga. Kaua e neke atu i te 3 hēkona ngā rauemi angiangi, ā, kaua e neke atu i te 5 hēkona ngā wāhanga whānui. Ko te tikanga, ka whakamahia te wai hei whakamahana (kāore e hiahiatia he whakamahana). Heoi anō, ka taea hoki te whakamahi i te hinu mō ngā wāhanga he uaua te āhua hei karo i te rerekētanga.
(2) Te rongoā koroheketanga o te parahi beryllium
Ko te pāmahana pakeketanga o te parahi beryllium e pā ana ki te ihirangi Be. Ko ngā koranu katoa kei roto i te iti iho i te 2.1% Be me pakeke. Mō ngā koranu he nui ake te Be i te 1.7%, ko te pāmahana pakeketanga tino pai ko te 300-330°C, ā, ko te wā pupuri ko te 1-3 hāora (i runga i te āhua me te matotoru o te wāhanga). Mō ngā koranu hiko tino kaha te kawe hiko me te Be iti iho i te 0.5%, nā te pikinga o te ira rewa, ko te pāmahana pakeketanga tino pai ko te 450-480°C, ā, ko te wā pupuri ko te 1-3 hāora. I ngā tau tata nei, kua whakawhanakehia hoki te pakeketanga wāhanga-rua me te wāhanga-maha, arā, ko te pakeketanga wā poto i te pāmahana teitei, kātahi ka pakeketanga wā roa i te pāmahana iti. Ko te painga o tēnei ko te whakapai ake i te mahi engari ka whakaitihia te whakarerekētanga. Hei whakapai ake i te tika o te āhua o te parahi beryllium i muri i te pakeketanga, ka taea te whakamahi i ngā taputapu mō te pakeketanga, ā, i ētahi wā ka taea te whakamahi i ngā wāhanga e rua o te maimoatanga pakeketanga.
(3) Te rongoā whakaiti ahotea o te parahi beryllium
Ko te pāmahana whakamahana o te parahi beryllium he 150-200℃, ā, ko te wā pupuri he 1-1.5 hāora. Ka taea te whakamahi hei whakakore i te ahotea toenga i puta mai i te tapahi whakarewa, te whakatikatika, te hanga matao, me ētahi atu, me te whakau i te āhua me te tika o ngā waahanga i te wā e whakamahia ana mo te wa roa.
