Aluminum Alloy mai Girma: Al-Sc Alloy

Al-Sc alloy wani nau'i ne na kayan aikin aluminum mai girma. Akwai da dama hanyoyin da za a inganta yi na aluminum gami, daga cikin abin da micro-alloying ƙarfafawa da kuma toughening shi ne iyakar filin high-yi aluminum gami bincike a cikin 'yan 20 shekaru.

The narkewa batu na scandium ne 1541 ℃, da na aluminum ne 660 ℃, don haka scandium dole ne a kara zuwa aluminum gami a cikin nau'i na master gami, wanda shi ne key albarkatun kasa shirya aluminum gami dauke da scandium. Akwai hanyoyi da yawa don shirya manyan allurai, kamar hanyar doping, scandium fluoride, hanyar rage yawan zafin jiki na scandium oxide, hanyar lantarki narkakken gishiri da sauransu. "

Hanyar doping ita ce kai tsaye ƙara ƙarfe scandium zuwa ga al'ada na aluminum, wanda yake da tsada, kona hasara a cikin aikin narkewa da kuma tsadar kayan masarufi.

Ana amfani da hydrogen fluoride mai guba a cikin shirye-shiryen scandium fluoride ta hanyar rage rage zafin ƙarfe na scandium fluoride, wanda ke da kayan aiki masu rikitarwa da zafin rage zafin ƙarfe na ƙarfe.

Matsakaicin farfadowa na scandium ta hanyar rage zafin ƙarfe na scandium oxide shine kawai 80%;

Narkar da narkar da gishiri electrolysis na'urar yana da rikitarwa kuma yawan juzu'i bai yi yawa ba.

Bayan kwatanta da zaɓi, ya fi dacewa don shirya Al-Sc master alloy ta amfani da hanyar rage zafi na ScCl narkar da gishiri Al-Mg.

Amfani:

Ƙara alama scandium zuwa aluminum gami zai iya inganta tace hatsi da kuma ƙara recrystallization zafin jiki da 250℃~280℃. Yana da mai sarrafa hatsi mai ƙarfi da ingantacciyar mai hana recrystallization don alloy na aluminum, wanda ke da tasirin gaske akan th.e tsarin da kaddarorin da gami da ƙwarai inganta ƙarfinsa, taurin, weldability da lalata juriya.

Scandium yana da tasiri mai kyau na ƙarfafa tarwatsawa akan aluminum, kuma yana kiyaye tsayayyen tsarin da ba a sake shi ba a cikin aiki mai zafi ko jin zafi. Wasu allunan zanen gado ne na birgima mai sanyi tare da nakasu mai girma, waɗanda har yanzu suna kula da wannan tsarin ko da bayan annashuwa. A hanawa na scandium a kan recrystallization iya kawar da recrystallization tsarin a cikin zafi shafi yankin Weld, The subgrain tsarin na matrix za a iya kai tsaye canjawa wuri zuwa matsayin-simintin gyare-gyare na weld, wanda ya sa da welded hadin gwiwa na aluminum gami dauke da scandium. babban ƙarfi da juriya na lalata.

Tasirin scandium akan juriya na lalata aluminum gami kuma shine saboda gyaran ƙwayar hatsi da hana tsarin recrystallization.

Bugu da ƙari na scandium kuma zai iya sa aluminium alloy ya sami kyakkyawan superplasticity, da haɓakar allo na aluminum tare da 0.5% scandium na iya kaiwa 1100% bayan maganin superplastic.

Saboda haka, Al-Sc gami da ake sa ran zama wani sabon ƙarni na nauyi tsarin kayan for Aerospace, jirgin sama da kuma jirgin ruwa masana'antu, wanda aka yafi amfani da waldi load tsarin sassa na Aerospace, jirgin sama da jirgin, aluminum gami bututu ga alkaline m matsakaici yanayi. Tankunan mai na jirgin kasa, mahimman sassan tsarin jiragen kasa masu sauri, da sauransu

Hasashen aikace-aikace:

Sc-dauke da aluminum gami yana da fadi da aikace-aikace bege a high-tech sassan kamar jirgin ruwa, Aerospace masana'antu, roka da makami mai linzami, nukiliya makamashi, da dai sauransu Ta ƙara alama scandium, yana da bege don ci gaba da jerin sabon-tsara high-yi aiki. Aluminum gami da kayan aikin da aka yi amfani da su a kan abin da ke cikin aluminum gami, irin su ultra-high ƙarfi da high tauri aluminum gami, high-ƙarfi lalata-resistant aluminum gami, high-ƙarfi neutron sakawa iska mai guba aluminum gami da sauransu.These alloys za su sami mai matukar kyau m.
