Mmetụta nke ihe adịghị ọcha na aluminom Alloy

Vanadium na-etolite valvụ refractory VAl11 na aluminom alloy, nke na-ekere òkè n'ịnụcha ọka na usoro ịgbaze na nkedo, mana mmetụta dị ntakịrị karịa nke titanium na zirconium. Vanadium nwekwara mmetụta nke imezigharị nhazigharị recrystallization na ịbawanye okpomọkụ recrystallization.

 

Ihe siri ike nke calcium na aluminom alloy dị oke ala, ọ na-emepụta ihe CaAl4 na aluminom. Calcium bụkwa ihe dị elu nke aluminom alloy. Aluminom alloy nwere ihe dị ka 5% calcium na 5% manganese nwere superplasticity. Calcium na silicon na-etolite CaSi, nke na-adịghị edozi na aluminom. Ebe ọ bụ na ọnụ ọgụgụ nke ngwọta siri ike nke silicon na-ebelata, conductivity nke ụlọ ọrụ mmepụta ihe dị ọcha aluminum nwere ike ime ka ọ dịkwuo mma. Calcium nwere ike imeziwanye mbelata arụmọrụ nke aluminom alloy. CaSi2 enweghị ike iwusi ọgwụgwọ okpomọkụ nke aluminom alloy ike. Chọpụta calcium bara uru iji wepụ hydrogen na aluminum gbazere.

 

Lead, tin, na bismuth ọcha bụ ọla na-agbaze obere. Ha nwere obere solubility siri ike na aluminom, nke na-ebelata ike nke alloy, mana ọ nwere ike imeziwanye arụmọrụ ịkpụ. Bismuth na-agbasawanye n'oge siri ike, nke bara uru maka nri. Ịgbakwunye bismuth na nnukwu magnesium alloys nwere ike igbochi "sodium brittleness".

 

A na-ejikarị Antimony eme ihe dị ka ihe ngbanwe na ihe nkedo aluminom alloys, a na-ejikarị ya eme ihe na alloys aluminom arụpụtara. Naanị dochie bismuth na Al-Mg arụpụtara aluminom alloys iji gbochie mgbaka sodium. Mgbe agbakwunyere ihe antimony na ụfọdụ Al-Zn-Mg-Cu alloys, arụmọrụ nke ịpị ọkụ na ịpị oyi nwere ike imeziwanye.

 

Beryllium nwere ike melite nhazi ihe nkiri oxide na aluminom arụpụtara ma belata mfu ọkụ na ntinye n'oge nkedo. Beryllium bụ ihe na-egbu egbu nke nwere ike ịkpata nsị nfụkasị ahụ. Ya mere, aluminom alloys nke na-abanye na kọntaktị nri na ihe ọṅụṅụ enweghị ike ịnwe beryllium. A na-achịkwa ọdịnaya nke beryllium na ihe ịgbado ọkụ n'okpuru 8μg / ml. Aluminom alloy eji dị ka ntọala ịgbado ọkụ kwesịkwara ịchịkwa ọdịnaya nke beryllium.

 

Sodium fọrọ nke nta ka ọ bụrụ ihe a na-adịghị ahụkebe na aluminom, ike kachasị ike bụ ihe na-erughị 0.0025%, ebe mgbaze nke sodium dị ala (97.8 ° C). Mgbe sodium dị na alloy, a na-agbanye ya n'elu dendrites ma ọ bụ oke ọka n'oge ike. N'oge nhazi okpomọkụ, sodium na oke ọka na-etolite akwa adsorption nke mmiri mmiri, na mgbe mgbawa na-egbuke egbuke na-eme, a na-emepụta ogige NaAlSi, ọ dịghị sodium n'efu dị, na "sodium brittleness" adịghị eme. Mgbe ọdịnaya magnesium karịrị 2%, magnesium ga-ewere silicon wee mee ka sodium efu pụta, na-ebute "sodium embrittlement". Ya mere, aluminom alloys magnesium dị elu anaghị ekwe ka ọ jiri nnu nnu sodium mee ihe. Usoro iji gbochie "sodium embrittlement" bụ usoro chlorination, nke na-eme ka sodium ghọọ NaCl ma na-agbanye ya n'ime slag, na-agbakwụnye bismuth na-eme ka ọ bụrụ Na2Bi wee banye na metal matrix; na-agbakwunye antimony iji mepụta Na3Sb ma ọ bụ ịgbakwunye ụwa na-adịghị ahụkebe nwekwara ike ịrụ otu ọrụ ahụ.
