Dab tsi yog qhov kub siab aluminium alloys?
Kub kub aluminium alloy
Cov tsoos kub-kub aluminium alloys xws li A4032 lossis A2618 yog siv rau hauv kev ua haujlwm siab pistons, aerospace airframes thiab lwm yam khoom. Tshaj 300 degree, cov alloys poob lub zog tseem ceeb. Txhawm rau kov yeej qhov kev txwv no, cov tshiab aluminium alloys tsim los ntawm kev ua hmoov nplej tau tsim. Ib txhia ntawm cov high-temperature aluminium alloys yuav hloov titanium los yog txawm hlau.
Cov alloys muaj kev ruaj ntseg zoo heev, txawm tias tom qab ntau pua teev ntawm qhov kev pabcuam kub, thiab zoo dua li cov pa hluav taws xob kub kub xws li A4032 thiab A2618.
Feem ntau cov tshiab high-temperature aluminium alloys xav tau kev ua haujlwm tshiab, xws li kev ua cov hmoov nplej siab heev. Tsis tas li ntawd, cov txheej txheem xws li nyem casting kuj tseem siv los tsim cov khoom siv hluav taws xob ntxiv cov hlau matrix.
Lub hom phiaj ntawm cov txheej txheem tshiab no yog kom ua tiav cov microstructure zoo dua thiab muaj zog dua. Cov txheej txheem solidification sai tso cai rau ntau dua solubility ntawm cov alloying ntsiab vim lub siab txias npaum li cas.
