Scandiumchinhu chekuchinja uye chimwe chezvinhu zvisingawanzoitiki zvepasi. Iine zvinhu zvakanakisa senge kupfava, inoshanda makemikari zvimiro, yakakwirira conductivity uye yakaderera chaiyo giravhiti. Kana yakawedzerwa kune aruminiyamu alloys, inogona kuvandudza zvakanyanya simba, kuoma uye zvimwe zvinhu zvealloys. Irwo rudzi rutsva rwekutsvaga chinhu chekugadzirwa kwepamusoro-simba, high-heat-resistant uye high-corrosion-resistant aluminium alloys. Sezvo nzvimbo yakanyunguduka ye scandium yakakwirira kwazvo, pa 1541 ° C, nepo kunyunguduka kwealuminium inongova 660 ° C, nzvimbo dzakanyunguduka dzesimbi mbiri dzakasiyana zvakanyanya, saka scandium inofanira kuwedzerwa kune aruminiyamu alloy muchimiro chepakati alloy. Naizvozvo, thealuminium-scandium yepakati alloyndiyo kiyi mbishi zvinhu kugadziriraaluminium-scandium alloys.
Kuwedzera huwandu hwe scandium (0.15 ~ 0.5wt%) kune aruminiyamu alloys inogona kuita yakanaka alloying basa. Chekutanga, inogona kunyatsonatsa zviyo zveakakandirwa alloys uye ine simba rekunatsa zviyo zvealuminium alloys. Chechipiri, inogona kuwedzera tembiricha recrystallization ne 250 ℃ ~ 280 ℃, kubvisa chimiro chakagadziridzwa munzvimbo inopisa-yakakanganiswa ye weld, uye iyo yakadzika dhizaini yematrix inogona kuchinjika yakananga kune yakakandwa chimiro che weld kudzivirira kupisa kupisa uye kuvandudza kuneta kuputsika kuramba kwealuminium alloy. Iyo inoshanda recrystallization inhibitor yearuminiyamu alloys uye ine zvakakosha pachimiro uye zvimiro zvealloy, inovandudza zvakanyanya simba rayo, kuomarara, elastic modulus, welding performance, kupisa kupisa, corrosion resistance uye kuramba neutron radiation kukuvara. Parizvino, zvinozivikanwa kuti simba realuminium-scandium alloyinogona kusvika kupfuura 750MPa, uye elastic modulus inogona kudarika 100GPa, iyo iri 30% yakakwirira kupfuura iyo yechinyakare aruminiyamu alloys. Chechitatu, inogona kuita basa rakanaka mukupararira kwekusimbisa, kuchengetedza yakagadzikana isina-recrystallized chimiro mumamiriro ekugadzirisa kupisa kana annealing kurapwa, uye ine maitiro ekugadzirisa kwakanaka uye kutonhora uye kugadzikana kwepamusoro kwekushisa. Chechina, inogona kuita kuti aruminiyamu alloys ave yakanaka superplasticity. Mushure mekurapa kwepamusoro-soro, kurebesa kwealuminium alloys ine inenge 0.5% scandium yakawedzerwa inogona kusvika 1100%.
Zvichienderana neakanakisa ma mechanic properties ealuminium-scandium alloys ataurwa pamusoro apa, achipaza nepakati pebhodhoro rechinyakare aruminiyamu alloy simba, uye achiri kuchengetedza kunaka processability, zvigadzirwa zvakagadzirwa nearuminiyamu-scandium alloys matsva zvishoma nezvishoma zvakatanga kuoneka mumisika yenyika dzakasimukira dzakadai seEurope neUnited States. Aluminium-scandium alloys imhando yemhando yepamusoro-soro yealuminium alloy ine simba repamusoro, kusimba kwepamusoro, uye kureruka. Ndivo akanakira zvinhu kuti ndege structural zvikamu, bhasikoro mafuremu, gorofu makirabhu, etc. Ivo zvakare chizvarwa chitsva lightweight uye mukuru-kuita aruminiyamu aruminiyamu structural zvinhu nokuda kwekucheka-kumucheto minda yenyika kudzivirira uye zvehondo indasitiri zvakadai ngarava, avhiyesheni, Aerospace, simba renyukireya, uye zvombo. Iwo anonyanya kushandiswa kukwenenzvera zvinotakura zvinhu zvemuchadenga, zvendege, uye ngarava, pamwe nealuminium alloy mapaipi e alkaline corrosive media nharaunda, matangi emafuta echitima, uye makiyi ezvikamu zvezvitima zvinomhanya. Iwo anoshandiswa zvakanyanya mumhepo, zvekufambisa, indasitiri yenyukireya, zvemagetsi, midziyo yekurongedza, uye mamwe minda.
Parizvino, kune marudzi anopfuura chiuru emhando dzealuminium alloy zvinhu munyika, izvo zvakabatsira zvikuru mukufambira mberi kwevanhu. Nekuvandudzwa kwesainzi uye tekinoroji uye nekuvandudzwa kwemararamiro, nyika yangu iri kuda kukurumidza kugadzira maaruminiyamu matsva anoshanda epamusoro. Kuvandudzwa kwemari yakaderera scandium-aluminium epakati alloys kunogona kuisa hwaro hwakasimba hwekuvandudzwa kwezvinhu izvi zvemhando yepamusoro, kusimudzira zvikuru kusimukira kweindasitiri yearuminiyamu yenyika yangu neindasitiri yescandium, uye kukurudzira kubatanidzwa kweindasitiri yenyika yangu nearuminiyamu indasitiri yepasi rose. Nokudaro, chirongwa chekugadzirira chealuminium-scandium (yepakati) alloy inokosha zvikuru uye inofanirwa, uye inzira yakakosha yekugadzirwa kwealuminium alloy zvinhu mune ramangwana.
Isu tine hunyanzvi mukupa Aluminium Scandium Alloy ine yemhando yepamusoro kugamuchirwataura nesukuwana mutengo
