Lub siab ua tau zoo aluminium alloy: al-sc coloy

Al-Sc Alloy yog hom kev ua tau zoo aluminium alloy. Muaj ntau txoj hauv kev los txhim kho kev ua tau zoo ntawm txhuas ib coloy, ntawm cov khoom siv hluav taws xob micro-alloy yog cov pem hauv ntej kev ua tau zoo aluminium

Lub suab nrov ntawm scandium yog 1541 ℃, thiab ntawm txhuas yog 660, yog li ntawd scandium cov khoom siv rau kev npaj cov khoom tseem ceeb rau kev npaj cov khoom siv tseem ceeb rau kev npaj aluminium alloy muaj scandium ancoy muaj scandium. Muaj ntau txoj hauv kev los npaj cov qauv ua kom zoo, scandium fluoride, molten ntsev electrolysis thiab lwm yam. "

Doping txoj kev yog kom ncaj qha ntxiv hlau scandium rau aluminium alloy, uas kim, hlawv poob rau hauv cov txheej txheem smelting thiab tus nqi siab ntawm tus tswv alloy

Kev ua kom cov tshuaj fluoride hydrogen fluoride yog siv nyob rau hauv kev npaj ntawm scandium thiav tshuaj fluoride los ntawm cov khoom fluoride

Tus nqi rov qab ntawm scandium los ntawm hlau thermal txo ntawm scandium oxide tsuas yog 80%;

Molten ntsev electrolysis yog cov nyom thiab cov nqi hloov siab los yog tsis siab.

Tom qab sib piv thiab xaiv, nws yog qhov tsim nyog dua los npaj al-sc tswv alloy los ntawm kev siv SCCL Molten ntsev al-Mg thermal txo cov txheej txheem.

Siv:

Ntxiv Trace Scandium rau txhuas alloy tuaj yeem txhawb nqa cov khoom siv roj fab thiab nce recrystallization kub txog 250℃Tom qab 280℃Cov. Nws yog lub haib grain constiner thiab zoo recrystallization inhileorization rau aluminium alloy, uas muaj qhov cuam tshuam pom ntawm thTus qauv thiab cov khoom ntawm cov alloy thiab heev txhim kho nws lub zog, hardness, weldability thiab corrosion tsis kam.

Scandium muaj qhov zoo tshem tawm cov kev siv zog ua rau txhuas, thiab tswj hwm qhov ruaj khov tsis-recrystallized cov qauv hauv kev ua haujlwm kub lossis kev kho mob. Qee cov alloys tau txias cov ntawv qhia nrog kev deformation zoo, uas tseem tswj cov qauv no txawm tias tom qab annealing. Qhov inhibition ntawm kev hloov kho ntawm cov qauv recrystallization nyob rau hauv matrix muaj cov qauv cua sov muaj lub zog loj thiab corrosion tsis kam.

Cov nyhuv ntawm scandium ntawm corrosion tsis kam ntawm aluminium alloy kuj yog vim muaj cov qoob loo nplej thiab inhibition ntawm cov txheej txheem recrystallization.

Qhov sib ntxiv ntawm scandium tuaj yeem ua kom cov aluminium alloy muaj zoo superplasticity, thiab elongation ntawm txhuas alloy nrog 0.5% scandium alloy nrog 0.00% tom qab kho superplastic kev kho mob.

Yog li no, al-sc alloy yuav tsum tau ua ib tiam neeg tshiab ntawm lub teeb roj av, kev lag luam roj av, cov cuab yeej tseem ceeb ntawm cov tsheb ciav hlau loj, cov tsheb nqaj hlau loj, thiab lwm yam

Daim ntawv thov kev cia:

SC-muaj aluminoy alloy muaj cov chaw tsim nyog xws li lub nkoj aluminium, muaj kev cia siab los ntawm ultra-siab, high zog aluminium alloy, high-lub zog neutriariation Resistant aluminium alloy thiab yog li ntawm oneoys alloys yuav muaj ib qho kev lag luam txaus nyiam heev hauv aerospace vim tias lawv cov tsheb ciav hlau zoo, thiab tuaj yeem siv rau hauv cov tsheb ciav hlau thiab tsheb ciav hlau ceev. Yog li ntawd, scandium-muaj aluminoy alloy tau dhau los ua lwm qhov kev sib tw thiab muaj qee cov khoom siv scandium cov khoom siv thiab muaj kev lag luam tseem ceeb tshaj plaws, cov khoom lag luam loj. Nws yog ntawm ePOCH-ua qhov tseem ceeb los tsim cov ntaub ntawv txhuas alsoy rau cov kev lag luam scandages hauv Suav teb thiab txhawb nqa kev lag luam scandium thiab txhawb nqa kev lag luam hauv tebchaws hauv Suav teb.
