Alloy aluminom na-arụ ọrụ dị elu: Al-Sc Alloy

Al-Sc alloy bụ ụdị alloy aluminum na-arụ ọrụ dị elu. Enwere ụzọ dị iche iche iji melite arụmọrụ nke alloy aluminum, n'ime nke micro-alloying ike na ike siri ike bụ mpaghara mpaghara nke nchọpụta alloy alloy dị elu na-arụ ọrụ na afọ 20 na-adịbeghị anya.

Ebe na-agbaze nke scandium bụ 1541 ℃, na nke aluminom bụ 660 ℃, yabụ a ga-agbakwunye scandium na alloy aluminum n'ụdị nnukwu alloy, nke bụ isi akụrụngwa maka ịkwadebe alloy aluminum nwere scandium. Enwere ụzọ dị iche iche iji kwadebe alloys nna ukwu, dị ka usoro doping, scandium fluoride, usoro mbelata okpomọkụ nke scandium oxide metal, usoro nnu a wụrụ awụ na ihe ndị ọzọ. "

Usoro doping bụ ịgbakwunye metal scandium na alloy aluminom, nke dị oke ọnụ, na-ere ọkụ na usoro ịgbaze na ọnụ ahịa dị elu nke nnukwu alloy.

A na-eji hydrogen fluoride na-egbu egbu mee ihe na nkwadebe nke scandium fluoride site na usoro mbelata metal thermal nke scandium fluoride, nke nwere akụrụngwa mgbagwoju anya na nnukwu mbelata okpomọkụ metal.

Ọnụego mgbake nke scandium site na mbelata thermal metal nke scandium oxide bụ naanị 80%;

Ngwaọrụ electrolysis nke nnu a wụrụ awụ dị mgbagwoju anya na ọnụego ngbanwe adịghị elu.

Mgbe atụnyere na nhọrọ, ọ ka mma ịkwadebe Al-Sc master alloy site na iji ScCl a wụrụ awụ nnu Al-Mg thermal Mbelata usoro.

Na-eji:

Ịgbakwunye trace scandium na aluminom alloy nwere ike ịkwalite nnụcha ọka na ịbawanye okpomọkụ recrystallization site na 250℃~280℃. Ọ bụ onye na-anụcha ọka siri ike yana ihe mgbochi recrystallization dị irè maka alloy aluminum, nke nwere mmetụta doro anya na th.e Ọdịdị na Njirimara nke alloy na ukwuu mma ya ike, hardness, weldability na corrosion iguzogide.

Scandium nwere mmetụta dị mma na-agbasawanye ike na aluminom, ma na-edobe usoro kwụsiri ike na-abụghị nke recrystallized na-arụ ọrụ na-ekpo ọkụ ma ọ bụ na-ekpo ọkụ. Ụfọdụ alloys bụ oyi akpọrepu Ibé akwụkwọ na nnukwu nrụrụ, nke ka na-ejigide a Ọdịdị ọbụna mgbe annealing. Mgbochi nke scandium na recrystallization nwere ike iwepụ ihe owuwu recrystallization na mpaghara okpomọkụ emetụtara weld, enwere ike ibufe usoro nke subgrain nke matriks ozugbo na usoro nkedo nke weld, nke na-eme ka nkwonkwo welded nke aluminum alloy nwere scandium nwere. ike dị elu na nguzogide corrosion.

Mmetụta nke scandium na nguzogide corrosion nke aluminom alloy bụkwa n'ihi nhazi ọka na mgbochi nke usoro recrystallization.

Mgbakwunye nke scandium nwekwara ike ime ka aluminum alloy nwee ezigbo superplasticity, na elongation nke aluminum alloy na 0.5% scandium nwere ike iru 1100% mgbe superplastic ọgwụgwọ.

Ya mere, a na-atụ anya na Al-Sc alloy ga-abụ ọgbọ ọhụrụ nke ihe nrụpụta dị arọ maka ikuku, ụgbọ elu na ụlọ ọrụ ụgbọ mmiri, nke a na-ejikarị eme ihe maka ịgbado ọkụ akụkụ akụkụ nke ikuku, ụgbọ elu na ụgbọ mmiri, aluminom alloy ọkpọkọ maka alkaline corrosive ọkara gburugburu, tankị mmanụ ụgbọ oloko, akụkụ nhazi isi nke ụgbọ oloko na-agba ọsọ, wdg
