ʻO ke kuleana a me ka mana o nā mea like ʻole i ka alumini alumini ma nā waiwai o ka alumini

E like me kou ike.kā mākouʻoki tile alumini/ʻaʻahu alumini/alakaʻi alumini kiʻi / alumini hoʻokalakupua kiʻi i hana ʻia me 6063 alumini alumini.ʻo ka mea alumini ka mea nui.a ʻo ke koena e like me lalo.

A i kēia lā e wehewehe mākou i ke kuleana a me ka mana o nā mea like ʻole i nā alumini alumini i nā waiwai o nā mea alumini.

 

mea keleawe

Ke 548 ka hapa nui o ka alumini keleawe o ka alumini keleawe, ʻo ka nui o ka solubility o ke keleawe i ka alumini he 5.65%, a ke hāʻule ka mahana i 302, ʻo ka solubility o ke keleawe he 0.45%.He mea koʻikoʻi ke keleawe a loaʻa kekahi hopena hoʻoikaika paʻa.Eia kekahi, ʻo CuAl2 i hoʻokahe ʻia e ka ʻelemakule he hopena hoʻoikaika ʻelemakule.ʻO ka mea keleawe i loko o nā alumini alumini he 2.5% a hiki i ka 5%, a ʻoi aku ka maikaʻi o ka hoʻoikaika ʻana inā ʻo ka ʻike keleawe he 4% a 6.8%, no laila aia ka ʻike keleawe o ka hapa nui o nā alumini alumini paʻakikī i kēia pae.

ʻĀpana silikoni

Ke loaʻa ka ʻāpana waiwai o ka alumini o ka ʻōnaehana Al-Si i ka mahana eutectic o 577 °C, ʻo ka nui o ka solubility o ke silika i loko o ka hopena paʻa he 1.65%.ʻOiai e emi ana ka solubility me ka emi ʻana o ka mahana, ʻaʻole hiki ke mālama ʻia kēia mau alloys.Loaʻa i nā Al-Si alloys ka maikaʻi o ka castability a me ke kūpaʻa corrosion.

Inā hoʻohui ʻia ka magnesium a me ke silika i ka alumini i ka manawa like e hana ai i ka alumini-magnesium-silicon alloy, ʻo ka pae hoʻoikaika ʻo MgSi.He 1.73:1 ka lakio nui o ka magnesium a me ke silika.I ka hoʻolālā ʻana i ka haku mele Al-Mg-Si, pono e hoʻonohonoho ʻia ka ʻike o ka magnesium a me ke silika e like me kēia ratio ma ka substrate.ʻO kekahi mau Al-Mg-Si alloys, i mea e hoʻomaikaʻi ai i ka ikaika, e hoʻohui i ka nui kūpono o ke keleawe, a ma ka manawa like e hoʻohui i kahi nui kūpono o ka chromium e hoʻopau i ka hopena maikaʻi ʻole o ke keleawe ma ka pale ʻana i ka corrosion.

Al-Mg2Si alloy alloy equilibrium phase diagram ʻO ka nui loa o ka solubility o Mg2Si i ka alumini ma ka ʻāpana waiwai alumini he 1.85%, a he liʻiliʻi ka deceleration me ka emi ʻana o ka mahana.

I loko o nā alumini alumini deformed, ʻo ka hoʻohui ʻana o ke silika i ka alumini wale nō i kaupalena ʻia i nā mea welding, a ʻo ka hoʻohui ʻana o ke silicon i ka alumini he hopena hoʻoikaika.

ʻElemu Magnesium

ʻO ka ʻāpana waiwai o ka aluminika o ke kiʻikuhi equilibrium o ka Al-Mg alloy system, ʻoiai ke ʻano o ka solubility curve e hōʻike ana i ka emi ʻana o ka solubility o ka magnesium i ka alumini me ka emi ʻana o ka mahana, akā i ka hapa nui o nā alumini alumini deformed ʻoihana, ʻo ka ʻike o ka magnesium. emi iho ma lalo o 6%.He haʻahaʻa hoʻi ka ʻike silika.ʻAʻole hiki ke hoʻoikaika ʻia kēia ʻano o ka alloy e ka mālama ʻana i ka wela, akā loaʻa iā ia ka weldability maikaʻi, ke kūpaʻa corrosion maikaʻi, a me ka ikaika waena.

ʻIke ʻia ka hoʻoikaika ʻana o ka magnesium i ka alumini.No kēlā me kēia 1% hoʻonui i ka magnesium, e hoʻonui ʻia ka ikaika tensile ma kahi o 34MPa.Inā hoʻohui ʻia ka manganese ma lalo o 1%, hiki ke hoʻohui i ka hopena hoʻoikaika.No laila, ma hope o ka hoʻohui ʻana i ka manganese, hiki ke hoʻemi ʻia ka ʻike magnesium, a i ka manawa like, hiki ke hoʻemi ʻia ke ʻano wela wela.Eia kekahi, hiki i ka manganese ke hana i ka Mg5Al8 pūhui e hoʻoheheʻe like, a hoʻomaikaʻi i ka pale ʻana i ka corrosion a me ka hana kuʻi.

Manganese

ʻO 1.82% ka hikiwawe kiʻekiʻe loa o ka manganese i ka hoʻonā paʻa inā he 658 ka mahana eutectic i loko o ke kiʻikuhi equilibrium o ka ʻōnaehana Al-Mn.Ke piʻi mau nei ka ikaika o ka alloy me ka piʻi ʻana o ka solubility, a hiki i ka elongation ke kiʻekiʻe loa ke loaʻa ka manganese i 0.8%.Al-Mn Al-Mn Al-Mn Al-Mn Alloys non-old hardenable alloys, 'o ia ho'i, 'a'ole hiki ke ho'oikaika 'ia e ka hana wela.

Hiki i ka manganese ke pale i ke kaʻina hana recrystallization o ka alumini alumini, hoʻonui i ka mahana recrystallization, a hiki ke hoʻomaʻemaʻe nui i nā ʻōpala recrystallization.ʻO ka hoʻomaʻemaʻeʻana o nā'ōpala i hoʻopili houʻia ma muli o ke keʻakeʻa i ka uluʻana o nā'ōpala i hoʻopiliʻia ma o nā'āpana'āpana MnAl6 i hoʻopuehuʻia.ʻO kekahi hana a MnAl6 ka hoʻoheheʻe ʻana i ka hao haumia e hana (Fe, Mn) Al6, e hōʻemi ana i nā hopena ʻino o ka hao.

He mea koʻikoʻi ka manganese o nā alumini alumini, hiki ke hoʻohui wale ʻia e hana i nā Al-Mn binary alloys, a ʻoi aku ka nui o ka hui pū ʻana me nā mea hoʻohui ʻē aʻe, no laila ka hapa nui o nā alumini alumini i loko o ka manganese.

ʻElemu Zinc

ʻO ka solubility o ka zinc i loko o ka alumini he 31.6% inā he 275 ka hapa nui o ka alumini o ka Al-Zn alloy system equilibrium phase diagram, a hāʻule kona solubility i 5.6% i ka 125.

Ke hoʻohui ʻia ka zinc i ka alumini wale nō, ʻo ka hoʻomaikaʻi ʻana i ka ikaika o ka alumini alumini ma lalo o nā kūlana deformation he palena loa, a aia nō hoʻi ke ʻano o ka hoʻoikaika ʻana i ka corrosion cracking, e kaupalena ana i kāna noi.

Hoʻohui ʻia ʻo Zinc a me ka magnesium i ka alumini i ka manawa like e hana i kahi pae hoʻoikaika Mg/Zn2, he hopena hoʻoikaika nui i ka alloy.Ke piʻi aʻe ka Mg / Zn2 mai 0.5% a hiki i 12%, hiki ke hoʻonui nui ʻia ka ikaika tensile a me ka ikaika hua.ʻOi aku ka ʻike o ka magnesium ma mua o ka mea e pono ai no ka hoʻokumu ʻana i ka pae Mg/Zn2.I loko o nā alumini alumini paʻakikī, ke hoʻomalu ʻia ka ratio o ka zinc a me ka magnesium ma kahi o 2.7, ʻo ke koʻikoʻi ʻoi aku ka nui o ka pale ʻana i ka corrosion cracking.

Inā hoʻohui ʻia ke keleawe iā Al-Zn-Mg e hana i ka alloy Al-Zn-Mg-Cu, ʻo ka hopena hoʻoikaika matrix ka mea nui loa ma waena o nā alumini alumini, a he mea koʻikoʻi hoʻi ia i nā mea alumini alumini i ka aerospace, ʻoihana mokulele, a me ka uila. ʻoihana mana.
