ʻO ka hopena maikaʻi o ka honua kakaʻikahi ma nā mea metala non-ferrous i ʻike loa ʻia i nā alloy magnesium.ʻAʻole wale ka hoʻopili ʻana i nā mea hoʻohenehene Mg-RE, akā loaʻa ka hopena maopopo loa i ka Mg-Al, Mg-Zn a me nā ʻōnaehana alloy ʻē aʻe.ʻO kāna hana nui penei:
1. E hoʻomaʻemaʻe i ka palaoa
Hiki ke hoʻomaʻemaʻe i nā hua o ka magnesium a me ka magnesium alloys kūpono o nā ʻāina laha ʻole.ʻO ka mea mua e hoʻomaʻemaʻe i nā grainofs o ka hoʻonohonoho hoʻolei ʻana.ʻO ke ʻano o ka hoʻonohonoho hoʻolei ʻana i nā mea ʻenehana honua e hoʻomaʻemaʻe i ka magnesium alloy ʻaʻole ia ka hana o ka nuclei heterogeneous.ʻO ke ʻano o ka hoʻomaʻemaʻe ʻana i ka palaoa maikaʻi o ka magnesium a me ka magnesium alloy grain sinofs o nā mea honua laha ʻole ka piʻi ʻana o ka overcooling ma ka ʻoki ʻoki o ka crystallization.ʻO ka lua o ka pale ʻana i ka recrystallization a me ka ulu ʻana o ka palaoa i ke kaʻina hana wela a me ka hana annealing.
2. Hehee ka hoomaemae
ʻOi aku ka pilina o nā mea ʻeleʻele ʻeleʻele me ka ʻili ma mua o ka magnesium a me ka oxygen, no laila hiki ke waiho ʻia me ka Rare Earth oxides e hui pū me Mgo a me nā oxides ʻē aʻe i ka heheʻe a laila wehe i ka oxidizing.Hoʻopili me ka hydrogen a me ka mahu wai i loko o ka heheʻe, e hana ana a i ʻole nā mea hoʻoheheʻe honua i hiki i ka manaʻo o ka deoxygenation.Hiki ke hoʻohui pū i ka wai hoʻoheheʻe a hōʻemi i ka shrivellability o ka hoʻolei ʻana, holomua fineness.
3. Holomua lumi wela huila ikaika
ʻO ka hapa nui o nā mea honua i loko o ka magnesium ka nui o ka solubility paʻa, a me ka hāʻule ʻana o ka mahana he hoʻololi koʻikoʻi i ke degere o ka solubility, no laila, ʻoi aku ka nui o nā mea honua i hoʻohui ʻia me ka paʻa-soluble reinforcement, he mea hoʻoikaika ʻelemakule maikaʻi. ʻo ka magnesium alloy, kekahi mau mea hoʻohui honua laha ʻole a me ka hoʻoikaika dispersive.
4. Ke kūpaʻa wela o nā hana mechanical alloy holomua
ʻO nā mea o ka honua laʻa nā mea hoʻohui maikaʻi loa o ke kūpaʻa wela o ka magnesium alloy, hiki ke hoʻomaikaʻi maikaʻi i ka ikaika wela kiʻekiʻe o ka Mg alloy a me ke kiʻekiʻe kiʻekiʻe o ka creep resistance, ʻo nā kumu he nui: liʻiliʻi ka coefficient stenome honua i ka magnesium, hiki ke lohi. i lalo i ke kaʻina hana recrystallization a me ka holomua recrystallization wela, hoʻohui i ka elemakule hopena a me ka desoluble phase thermal paʻa, ʻO ka honua laha ʻole me ka helu heheʻe kiʻekiʻe i snouts i ka palena aniani, pale i ka misalignment o ka neʻe, a holomua ke kiʻekiʻe wela creep kū'ē.
5. Ke kū'ē kū'ē i nā mea hao hao
Ma muli o ka hoʻomaʻemaʻe ʻana o ka hoʻoheheʻe ʻana, ua hoʻemi ʻia nā hopena ʻino o ka hao haumia, a me nā mea ʻē aʻe, a laila hoʻomaikaʻi ʻia ke kūpaʻa corrosion.
