Raws li qhov sib txawv matrix, high-temperature alloys muab faib ua: hlau-raws li high-temperature alloys, nickel-based high-temperature alloys thiab cobalt-based high-temperature alloys. Ntawm lawv, nickel-based high-temperature alloys raug xa mus rau cov nickel-based alloys.
Cov yam ntxwv tseem ceeb ntawm cov nickel-raws li kub-kub alloys muaj xws li lub zog siab thiab zoo oxidation tsis kam thiab roj corrosion kuj nyob rau hauv thaj tsam ntawm 650 ~ 1000 degree. Hom alloy no tuaj yeem ua rau kub thiab txias deformed, nrog rau kev khiav hauj lwm kub ntau ntawm -253 degree mus rau 1320 degree, thiab muaj cov khoom siv zoo thiab cov khoom muaj zog thiab toughness.
Raws li lub ntsiab alloying ntsiab thiab microstructures nyob rau hauv cov hlau, npib tsib xee-raws li high-temperature alloys feem ntau yuav muab faib mus rau hauv cov khoom siv ntxiv dag zog rau hom thiab nag lossis daus reinforcing hom. Cov khoom siv ntxiv dag zog rau cov alloys txhim kho kev ua tau zoo los ntawm kev ntxiv cov ntsiab lus xws li chromium thiab tungsten, thaum nag lossis daus ntxiv dag zog rau cov khoom siv los ntawm kev tsim cov nag lossis daus.
