Ib tug tswv alloy yog lub hauv paus hlau zoo li txhuas, cov hlau, npib tsib xee, lossis tooj liab sib xyaw nrog ib lossis ob lub ntsiab lus. Nws yog tsim kom siv tau cov ntaub ntawv raw los ntawm kev lag luam hlau, thiab yog vim li cas peb thiaj li hu ua cov khoom lag luam alloy lossis raws li cov khoom lag luam tiav. Cov tswv alloys tau tsim tawm hauv ntau yam duab xws li ingot, waffle daim hlau, pas nrig hauv coils thiab lwm yam.
1. Dab tsi yog tus tswv alloys?
Tus tswv alloy yog ib cov khoom siv alloy siv rau kev ua kom haum nrog cov khoom sib xyaw ua ke los ntawm kev ua kom meej, yog li tus tswv alloy tseem yog hu ua casting tus tswv coing. Qhov laj thawj yog vim li cas tus tswv alloy yog hu ua "tus tswv alloy" yog tias nws muaj cov khoom siv tshuaj tiv thaiv cov noob caj noob ces ntau yam li cov khoom siv carbon monoxide), txawm tias muaj cov khoom siv carbide (xws li tau txais cov khoom lag luam carbon monoxide) Cov khoom siv uas twb muaj lawm siv cov ntaub ntawv siv kub siab, dual-theem tus tswv alloys, thiab cov pa roj hlau siv ntau yam.
2. Cov ntawv thov alloys
Muaj ntau ntau ntawm cov laj thawj rau kev ntxiv tus tswv alloys kom yaj. Ib qho ntawv thov loj muaj pes tsawg leeg, piv txwv li hloov cov khoom sib xyaw ntawm cov kua hlau kom paub cov tshuaj tshwj xeeb. Lwm daim ntawv thov tseem ceeb yog cov qauv tswj - muaj feem cuam tshuam rau microstructure ntawm cov hlau hauv lub Casting thiab cov txheej txheem solidification yog li hloov nws cov khoom. Cov khoom zoo li no suav nrog lub zog tshuab zog, ductility, conductivity, suminability, lossis nto tsos. Suav rau nws daim ntawv thov, tus tswv alloy feem ntau yog tau hais tias yog "tawv", "cov khoom siv sib txuas" lossis "hloov kho".
