Vanadium inoumba VAL11 refractory compound mualuminium alloy, iyo inobata basa mukunatsa zviyo mukunyunguduka nekukanda, asi mhedzisiro yacho idiki pane iyo yetitanium uye zirconium. Vanadium zvakare ine mhedzisiro yekunatsa iyo recrystallization chimiro uye kuwedzera tembiricha yekristaro.
Iyo yakasimba solubility yecalcium mualuminium alloy yakadzikira zvakanyanya, uye inoumba CaAl4 musanganiswa nealuminium. Calcium zvakare chinhu chepamusoro-soro chealuminium alloy. Aluminium alloy ine inenge 5% calcium uye 5% manganese ine superplasticity. Calcium uye silicon inoumba CaSi, iyo isinganyunguriki mualuminium. Sezvo huwandu hwemhinduro yakasimba yesilicon yakaderedzwa, iyo conductivity yeindasitiri yakachena aluminium inogona kuvandudzwa zvishoma. Calcium inogona kuvandudza kucheka kwealuminium alloy. CaSi2 haigone kusimbisa kurapwa kwekupisa kwealuminium alloy. Trace calcium inobatsira kubvisa hydrogen mualuminium yakanyungudutswa.
Lead, tin, uye bismuth elements isimbi inonyungudika yakaderera. Vane zvishoma yakasimba solubility mualuminium, iyo inoderedza zvishoma simba realloy, asi inogona kuvandudza kushanda kwekucheka. Bismuth inowedzera panguva yekusimba, iyo inobatsira pakudya. Kuwedzera bismuth kune yakakwira magnesium alloys inogona kudzivirira "sodium brittleness".
Antimony inonyanya kushandiswa sechigadziriso mune yakakandwa aruminiyamu alloys, uye haiwanzo kushandiswa muakagadzirwa aluminium alloys. Inongotsiva bismuth muAl-Mg yakagadzira aruminiyamu alloys kudzivirira sodium embrittlement. Kana iyo antimony element yawedzerwa kune mamwe maAl-Zn-Mg-Cu alloys, kuita kwekutsikirira kupisa uye kutonhora kudzvanya kunogona kuvandudzwa.
Beryllium inogona kuvandudza chimiro che oxide firimu muakagadzirwa aruminiyamu alloy uye kuderedza kupisa kurasikirwa uye inclusions panguva yekukanda. Beryllium chinhu chine chepfu chinogona kukonzera allergic poisoning. Naizvozvo, aruminiyamu alloys anosangana nechikafu uye zvinwiwa haagone kuve neberyllium. Izvo zviri mukati me beryllium mune welding zvinhu zvinowanzodzorwa pazasi 8μg/ml. Iyo aruminiyamu alloy inoshandiswa seye welding base inofanirawo kudzora zviri mukati me beryllium.
Sodium inenge isina kunyungudika mualuminium, iyo yakawanda yakasimba solubility isingasviki 0.0025%, uye nzvimbo yekunyunguduka yesodium yakaderera (97.8 ° C). Kana sodium iripo mualloy, inoshambadzirwa pamusoro pemadendrites kana miganhu yezviyo panguva yekusimba. Munguva yekupisa kwekupisa, sodium pamuganhu wezviyo inoumba mvura adsorption layer, uye kana brittle cracking ikaitika, NaAlSi compound inoumbwa, hapana sodium yemahara iripo, uye "sodium brittleness" haiitike. Kana iyo magnesium inodarika 2%, magnesium inotora silicon uye precipitate yemahara sodium, zvichikonzera "sodium embrittlement". Nokudaro, high-magnesium aluminium alloys haibvumirwi kushandisa sodium munyu fluxes. Nzira yekudzivirira "sodium embrittlement" ndiyo nzira yeklorini, iyo inoita sodium fomu NaCl uye inoibudisa mu slag, uye inowedzera bismuth kuti iite Na2Bi uye kupinda musimbi matrix; kuwedzera antimony kuumba Na3Sb kana kuwedzera isingawanzo pasi kunogona kuitawo basa rimwechete.
