A High Performance Aluminium Alloy: Al-Sc Alloy

Al-Sc alloy imhando yepamusoro-inoshanda aruminiyamu alloy. Pane nzira dzakawanda dzekuvandudza kushanda kwealuminium alloy, pakati peiyo micro-alloying kusimbisa uye kuomesera ndiyo nzvimbo yemuganhu wepamusoro-kushanda kwealuminium alloy tsvakurudzo mumakore makumi maviri achangopfuura.

Iyo yekunyunguduka kwe scandium i1541 ℃, uye iyo yealuminium i660 ℃, saka scandium inofanirwa kuwedzerwa kune aruminiyamu alloy muchimiro che master alloy, inova ndiyo kiyi mbishi yekugadzira aluminium alloy ine scandium. Pane nzira dzinoverengeka dzekugadzirira master alloys, senge nzira yedoping, scandium fluoride, scandium oxide simbi yekudzikisa kupisa nzira, yakanyungudutswa munyu electrolysis nzira uye zvichingodaro. “

Iyo doping nzira ndeyekuwedzera zvakananga simbi scandium kune aruminiyamu alloy, inodhura, kupisa kurasikirwa mukunyungudutsa uye kudhura kwakanyanya kwe master alloy.

Toxic hydrogen fluoride inoshandiswa mukugadzirira scandium fluoride nesimbi yekudzikisira nzira ye scandium fluoride, ine michina yakaoma uye yakakwira simbi yekudzikisa kupisa tembiricha.

Iyo yekudzoreredza mwero we scandium nesimbi yekupisa kuderedzwa kwe scandium oxide ndeye 80% chete;

Iyo yakanyungudutswa yemunyu electrolysis mudziyo wakaoma uye mwero wekutendeuka hauna kukwirira.

Mushure mekuenzanisa uye kusarudzwa, zvakanyanya kukodzera kugadzirira Al-Sc master alloy nekushandisa ScCl yakanyungudutswa munyu Al-Mg yekuderedza kupisa nzira.

Zvishandiso:

Kuwedzera trace scandium kune aruminiyamu alloy kunogona kusimudzira kukwenenzvera zviyo uye kuwedzera tembiricha yekristaro ne250.℃~280℃. Iyo ine simba yekunatsa zviyo uye inoshanda recrystallization inhibitor yealuminium alloy, ine simba riri pachena pae dhizaini uye zvimiro zvealloy uye inovandudza zvakanyanya simba rayo, kuoma, weldability uye corrosion resistance.

Scandium ine yakanaka yekuparadzira inosimbisa mhedzisiro paaluminium, uye inochengetedza yakagadzikana isina-yakagadziriswa chimiro mukushanda kunopisa kana kurapwa kweanoresa. Mamwe ma alloys anotonhora akakungurutswa mashizha ane deformation yakakura, iyo inoramba ichichengetedza chimiro ichi kunyangwe mushure mekuvhara. Iyo inhibition ye scandium pa recrystallization inogona kubvisa iyo recrystallization chimiro munzvimbo yekupisa yakakanganiswa ye weld, Iyo subgrain chimiro che matrix inogona kuendeswa zvakananga kune se-yakakandwa chimiro che weld, iyo inoita kuti yakashongedzerwa yekubatanidza yealuminium alloy ine scandium ine. kusimba kwepamusoro uye kusagadzikana kwekuora.

Mhedzisiro ye scandium pane corrosion resistance yealuminium alloy inokonzerwawo nekunatswa kwezviyo uye kuvharirwa kwekuita recrystallization.

Kuwedzerwa kwe scandium kunogonawo kuita kuti aluminium alloy ive yakanaka superplasticity, uye kurebesa kwealuminium alloy ne 0.5% scandium inogona kusvika 1100% mushure mekurapwa kwesuperplastic.

Naizvozvo, Al-Sc alloy inotarisirwa kuve chizvarwa chitsva chezvakareruka zvimiro zveaerospace, zvendege uye maindasitiri ezvikepe, ayo anonyanya kushandiswa welding mitoro yezvimiro zveaerospace, ndege uye ngarava, aluminium alloy mapaipi e alkaline corrosive medium nharaunda, matangi emafuta echitima, akakosha zvimiro zvezvitima zvinomhanya, nezvimwe

Tarisiro yekushandisa:

Sc-ine aruminiyamu alloy ine tarisiro yakakura yekushandisa mumadhipatimendi epamusoro-soro akadai sengarava, indasitiri yezvemuchadenga, roketi uye missile, simba renyukireya, etc. Nekuwedzera trace scandium, inotarisira kukudziridza mutsara wechizvarwa chitsva chepamusoro-kushanda. aruminiyamu alloy zvinhu zvichibva pane iripo aruminiyamu alloy, yakadai seye-ultra-high simba uye yakakwirira kusimba kwealuminium alloy, yakakwirira-simba-resistant aluminium alloy, yakakwirira-simba neutron irradiation resistant aluminium alloy uye zvichingodaro.Izvi zviwanikwa zvichange zvine zvinoyevedza zvikuru. tarisiro yekushandisa mune aerospace, simba renyukireya uye maindasitiri ekuvaka zvikepe nekuda kwehunhu hwawo hwakanakisa hwakakwana, uye anogona zvakare kushandiswa mumotokari dzakareruka nezvitima zvinomhanya. Naizvozvo, scandium-ine aruminiyamu alloy yave imwe inoyevedza uye yakanyanya kukwikwidza yakakwirira-inoshanda aruminiyamu alloy structural material mushure meAlLi alloy.China yakapfuma mune scandium zviwanikwa uye ine imwe nheyo ye scandium tsvakurudzo nekugadzirwa kwemaindasitiri, iyo ichiri mutengesi mukuru we scandium oxide. Izvo zvakakosha zvekugadzira zvigadzirwa zvealuminium alloy zvemhando yepamusoro uye yekudzivirira nyika muChina, uye inogona kupa AlSc kutamba kwakazara kune zvakanakira zviwanikwa zve scandium muChina uye kusimudzira kusimudzira indasitiri ye scandium nehupfumi hwenyika muChina. .
