Alloys yog dab tsi?

Ib qho hlau yog ib yam khoom uas muaj cov khoom siv hlau tsim los ntawm kev sib xyaw ntawm ob lossis ntau dua hlau lossis hlau uas tsis yog hlau. Nws feem ntau yog tsim los ntawm melting, sib tov, txias, thiab solidifying. Lub hardness ntawm alloys feem ntau yog siab dua li ntawm lawv cov constituent hlau, thaum lawv melting point feem ntau yog qis dua li ntawm cov constituent hlau.
Txhais
Ib qho hlau yog ib yam khoom tsim los ntawm kev sib xyaw ua ke ntawm ob lossis ntau lub ntsiab lus hlau, lossis hlau thiab tsis yog- hlau, uas muaj tsawg kawg yog ib qho hlau.
Lub cev muaj zog
Hardness: Feem ntau cov alloys muaj ib tug hardness siab dua lawv cov hlau constituent, yog li muaj zoo hnav tsis kam thiab deformation kuj.
Melting point: Lub melting point ntawm ib qho alloy feem ntau qis dua nws cov khoom siv hlau, uas ua rau cov alloy yooj yim dua rau yaj thiab tsim thaum ua.
Cov khoom siv tshuaj
Cov khoom siv tshuaj lom neeg ntawm cov hlau feem ntau yog sib xyaw ua ke ntawm cov khoom siv hlau thiab cov hlau tsis yog hlau. Piv txwv li, magnesium aluminium alloy tsuas yog ib feem yaj ntawm txhuas hauv sodium hydroxide tov, thaum magnesium tseem tsis hloov.
Classification thiab Application
Alloys tuaj yeem muab faib ua hlau hlau alloys (xws li hlau, tooj dag) lossis hlau tsis yog- hlau alloys (xws li txhuas alloys). Kev siv dav hauv ntau yam xws li tshuab, kev tsim kho, aerospace, thiab tsheb, alloys ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom lag luam thiab txuas ntxiv kev pab cuam lub neej vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb.
