ʻO ka Beryllium bronze kahi mea hana maʻamau i hoʻoikaika ʻia i ka ua.ʻO ke kaʻina hana wela maʻamau o ke keleawe beryllium ikaika kiʻekiʻe ka mālama ʻana i ka mahana ma 760 ~ 830 ℃ no ka manawa kūpono (ma ka liʻiliʻi he 60 mau minuke no ka pā 25mm mānoanoa), i hoʻoheheʻe ʻia ka beryllium atomic solute i loko o ka matrix keleawe e hana i ka mahele α o ka lattice cubic alo.Haʻina paʻa supersaturated.Ma hope mai, mālama ʻia ka mahana ma 320-340 °C no 2-3 mau hola e hoʻopau i ke kaʻina hana o ka desolubilization a me ka ua e hana ai i kahi γ' (CuBe2 metastable phase).Hoʻokumu ka hui ʻana o kēia māhele me ka matrix i kahi kahua koʻikoʻi e hoʻoikaika i ka matrix.ʻO ke kaʻina hana wela maʻamau o ke keleawe beryllium conductivity kiʻekiʻe e mālama i kahi manawa ma kahi kiʻekiʻe o 900-950 ° C e hoʻopau ai i ke kaʻina hana paʻa, a laila mālama iā ia ma 450-480 ° C no 2-4. hola e hoʻokō i ke kaʻina desolubilization a me ka ua.Ma muli o ka hoʻohui ʻia ʻana o ka cobalt a i ʻole nickel i ka huila, ʻo kāna mau mea hoʻoikaika hoʻopuehu ka hapa nui o nā pūhui intermetallic i hana ʻia e ka cobalt a i ʻole nickel a me ka beryllium.I mea e hoʻomaikaʻi hou aku ai i ka ikaika o ka alloy, ua hana pinepine ʻia kekahi pae o ka hana anu ma ka alloy ma hope o ka mālama ʻana i ka wela a ma mua o ka hoʻomaʻamaʻa ʻana i ka wela o ka wā kahiko, i mea e hoʻokō ai i ka hopena hoʻoikaika piha o ka paʻakikī o ka hana anu a me ka paʻakikī makahiki. .ʻAʻole ʻoi aku ka nui o kāna hana anu ma mua o 37%.Pono e hoʻokō ʻia ka hoʻoponopono wela e ka mea hana alloy.Ma hope o ke kuʻi ʻana o ka mea hoʻohana i nā ʻāpana i hoʻoponopono ʻia i ka wela a me ka ʻōwili anu i loko o nā ʻāpana, a laila hoʻomaʻamaʻa iā lākou iho i ka wela e loaʻa ai nā mea puna ikaika kiʻekiʻe.I nā makahiki i hala iho nei, ua hoʻomohala ʻo ʻAmelika i nā ʻāpana me ka mālama wela kahiko i hoʻopau ʻia e nā mea hana keleawe beryllium, a hiki i nā mea kūʻai ke kuʻi pololei iā lākou i mau ʻāpana no ka hoʻohana ʻana.Ma hope o ka hana ʻia ʻana o ka beryllium bronze e nā kaʻina hana like ʻole, ʻo nā leka ma ʻEulopa a me ʻAmelika no ka mokuʻāina alloy: ʻO ke ʻano o ka solution annealed state (annealed), aia ka alloy i ka ʻāina palupalu, maʻalahi e hoʻopaʻa ʻia a hana ʻia, a pono. e hana anu hou a i ʻole ka lapaʻau ʻelemakule pololei..ʻO H ke kūlana paʻakikī hana (paʻakikī).No ka laʻana, ʻo 37% o ke kēkelē hana anu he paʻakikī loa (H), 21% o ke kēkelē hana anu he semi-paʻakikī (1/2H), a ʻo 11% o ke kēkelē hana anu he 1. / 4 kūlana paʻakikī (1 / 4H), hiki i ka mea hoʻohana ke koho i ke kūlana palupalu a paʻakikī kūpono e like me ka paʻakikī o ke kuʻi ʻana i ke ʻano o ka ʻāpana.Hōʻike ʻo T i ke kūlana mālama wela (heat treatment) i ʻelemakule a hoʻoikaika ʻia.Inā ʻae ʻia ke kaʻina hana o ka hoʻoikaika piha ʻana o ka deformation a me ka ʻelemakule, ua hōʻike ʻia kona mokuʻāina e HT
