Hangarau Matua o te Parahi Beryllium (Te maimoatanga wera)
Ko te maimoatanga wera te tukanga tino nui mō tēnei pūnaha koranu. Ahakoa ka taea te whakapakeke i ngā koranu parahi katoa mā te mahi matao, he ahurei te parahi beryllium nā te mea ka taea te whakapakeke mā te maimoatanga wera pāmahana iti noa. E rua ngā mahi matua. Ko te tuatahi ka kiia ko te whakamahana otinga, ā, ko te tuarua, ko te whakapakeketanga o te ua, te pakeketanga rānei.
Te Whakamahana Otinga
Mō te koranu CuBe1.9 noa (1.8-2%), ka whakamahanahia te koranu i waenga i te 720°C me te 860°C. I tēnei wā, ka "rewa" te beryllium kei roto i te hanganga parahi (wāhanga alpha). Mā te tinei tere ki te pāmahana rūma ka mau tonu tēnei hanganga wairewa totoka. He tino ngohengohe, he ngāwari hoki te rauemi i tēnei wā, ā, ka taea te mahi matao mā te tuhi, te hanga hurihuri, te pane matao rānei. Ko te mahi whakamahana wairewa he wāhanga o te tukanga i te mira, ā, kāore i te whakamahia e te kiritaki i te nuinga o te wā. Ko te pāmahana, te wā i te pāmahana, te tere tinei, te rahi o te witi, me te pakeke he tawhā tino nui katoa, ā, e whakahaeretia ana e TANKII.
Te Whakapakari i te Tau
Mā te whakapakeketanga tawhito ka tino whakanui ake i te kaha o te rauemi. Ko te tikanga ka mahia tēnei tauhohenga i ngā pāmahana i waenga i te 260°C me te 540°C i runga i te koranu me ngā āhuatanga e hiahiatia ana. Mā tēnei huringa ka puta te beryllium rewa hei wāhanga momona i te beryllium (gamma) i roto i te matrix me ngā rohe kōhatu. Ko te hanganga o tēnei matū e hua ai te pikinga nui o te kaha o te rauemi. Ko te taumata o ngā āhuatanga miihini kua tutukihia ka whakatauhia e te pāmahana me te wā i te pāmahana. Me mōhio kāore he āhuatanga koroheketanga pāmahana rūma o te parahi beryllium.
