Nyob rau hauv ib tug alloy, nyob ntawd yog cov atom ntawm qhov sib txawv. Qhov me me los yog loj dua atoms yuam kev cov txheej ntawm atoms hauv cov hlau ntshiab. Qhov no txhais tau hais tias yuav tsum muaj zog ntau dua rau cov khaubncaws sab nraud povtseg dhau ib leeg. Cov alloy yog nyuaj dua thiab muaj zog dua tshaj tus ntshiab hlau.

Raws li, yog vim li cas alloys nyuaj dua cov hlau ntshiab GCSE?

Cov hlau nplaum muaj cov atom ntawm qhov sib txawv. Qhov no ua rau nws nyuaj rau cov khaubncaws sab nraud povtseg, yog li ntawd alloys yog nyuaj dua tus hlau ntshiab . Nws yog qhov nyuaj dua rau cov khaubncaws sab nraud povtseg ntawm cov atom kom swb rau ib leeg alloys . Tooj, kub thiab txhuas yog mos heev rau ntau siv.

Tsis tas li ntawd, qhov txawv ntawm cov hlau ntshiab thiab cov hlau alloy yog dab tsi? Los ntawm txhais, cov hlau ntshiab muaj ib lub ntsiab. Cov hlau nplaum muaj ob lossis ntau lub ntsiab lus lossis alloys melted thiab blended ua ke, yog li lawv cov tshuaj formulas muaj ntau tshaj ib lub caij. Piv txwv li, lub ntshiab hlau hlau tsuas muaj hlau atoms.

Tsis tas li ntawd, vim li cas alloys nyuaj dua li cov hlau ntshiab?

A hlau ntshiab muaj zoo tib yam atoms teem nyob rau hauv tsis tu ncua txheej. Cov khaubncaws sab nraud povtseg ntawm ib leeg yooj yim. Cov hlau nplaum yog nyuaj dua thiab muaj zog dua vim qhov sib txawv ntawm cov atoms sib xyaw hlau ua rau cov atomic txheej tsis tu ncua, yog li lawv tsis tuaj yeem swb yooj yim.

Vim li cas cov hlau ntshiab yog mos thiab malleable?

Hlau tau piav raws li tuaj yeem (tuaj yeem raug ntaus rau hauv nplooj ntawv) thiab ductile (tuaj yeem rub tawm mus rau hauv cov xov hlau). Qhov no yog vim muaj peev xwm ntawm cov atoms los dov ib leeg rau hauv txoj haujlwm tshiab yam tsis tau rhuav tshem cov hlau nplaum.
