Kev Paub Txog Alloys
Dec 25, 2021
Cov ntsiab lus ntawm alloy: Lub npe hu ua alloy yog hais txog cov khoom siv hlau tsim los ntawm kev sib xyaw ntawm ob lossis ntau dua cov hlau. Kev ua tau zoo ntawm ntau yam khoom siv hlau fused zoo dua li cov khoom siv hlau ntshiab. Yog li ntawd, txawm hais tias nws yog nyob rau hauv peb lub neej los yog nyob rau hauv kev ua hauj lwm, cov ntaub ntawv hlau belongs rau alloy khoom.
Cov qauv ntawm cov alloys: intermetallic alloys, sib tov alloys, khoom tov alloys.
Ob: Mixed alloys. Thaum cov kua alloy solidifies, cov khoom ntawm cov alloy yog crystallized nyias, xws li solder, bismuth-cadmium alloy, thiab lwm yam.
Alloy khoom:
Ib qho: Lub hardness feem ntau yog ntau dua li ntawm cov hlau hauv nws cov muaj pes tsawg leeg.
Qhov thib ob: Lub melting point ntawm cov alloys feem ntau yog qis dua qhov melting point ntawm ib qho ntawm cov khoom siv hlau hauv lawv cov khoom.
Peb: muaj zog corrosion kuj.
Common alloys: medical lead, low temperature solder, low temperature zinc alloy, lead-tin alloy, tin alloy, manganese steel, stainless steel, brass, bronze, cupronickel, solder, duralumin.
