ʻO ka ʻenehana nui o Beryllium Copper(Hoʻomaʻamaʻa wela)
ʻO ka hoʻomaʻamaʻa wela ka hana nui loa no kēia ʻōnaehana alloy. ʻOiai ua paʻakikī nā ʻāpana keleawe a pau e ka hana anu, ʻokoʻa ka beryllium copper i ka paʻakikī ʻana e ka mālama wela haʻahaʻa haʻahaʻa. Loaʻa i ʻelua mau ʻanuʻu kumu. Kapa ʻia ka mua he solution annealing a ʻo ka lua, ka ua a i ʻole ka paʻakikī makahiki.
Hoʻopiʻi Annealing
No ka huila maʻamau CuBe1.9 (1.8- 2%) ua hoʻomehana ʻia ka huila ma waena o 720°C a me 860°C. I kēia manawa ua "hoʻoheheʻe ʻia" ka beryllium i loko o ka matrix keleawe (alpha phase). Ma ke kinai wikiwiki ʻana i ka wela lumi e mālama ʻia kēia ʻano hoʻonā paʻa. ʻO ka mea ma kēia pae he palupalu a ductile a hiki ke hana maʻamau ma ke kaha kiʻi ʻana, hoʻowili ʻana, a i ʻole ke poʻo anu. ʻO ka hana annealing solution kahi ʻāpana o ke kaʻina hana ma ka wili a ʻaʻole i hoʻohana maʻamau ʻia e ka mea kūʻai. ʻO ka mahana, ka manawa i ka mahana, ka nui o ka ʻai, ka nui o ka palaoa, a me ka paʻakikī, he mau ʻāpana koʻikoʻi loa ia a mālama ʻia e TANKII.
Makahiki Paakiki
ʻO ka paʻakikī makahiki e hoʻonui nui i ka ikaika o ka mea. Hana ʻia kēia pane ma nā mahana ma waena o 260°C a me 540°C ma muli o ka alloy a me nā ʻano i makemake ʻia.
