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 ScCl narkar da gishiri Al-Mg thermal rage hanyar.

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 gami da aluminum, wanda ke da tasirin gaske akan th.e tsarin da kaddarorin na 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 tsarin na weld, wanda ya sa welded hadin gwiwa na aluminum gami dauke da scandium da high ƙarfi da lalata juriya.

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 alloy ana sa ran ya zama 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 sararin samaniya, jirgin sama da jirgin, aluminum gami bututu ga alkaline m matsakaici yanayi, Railway man tankuna, key tsarin sassa na high-gudun jirgin kasa da dai sauransu

Hasashen aikace-aikace:
