Piav alloy hardness Cov atoms yog teem rau hauv txheej. … Cov atoms me los yog loj dua ua rau cov txheej ntawm atoms nyob rau hauv cov hlau ntshiab. Qhov no txhais tau hais tias yuav tsum muaj lub zog ntau dua rau cov khaubncaws sab nraud povtseg rau ib leeg. Cov hlau yog nyuaj dua thiab muaj zog dua cov hlau ntshiab.
Vim li cas alloys nyuaj dua cov hlau ntshiab GCSE?
Alloys muaj cov atom ntawm qhov sib txawv. Qhov ntau thiab tsawg sib txawv no cuam tshuam qhov kev npaj ntawm atoms. Qhov no ua rau nws nyuaj rau cov khaubncaws sab nraud povtseg, yog li alloys nyuaj dua li cov hlau ntshiab. … Lawv muab sib xyaw nrog lwm cov hlau los ua rau lawv nyuaj rau kev siv txhua hnub.
Puas alloys ib txwm muaj zog dua cov hlau ntshiab?
Puas yog cov hlau nplaum muaj zog dua li cov hlau ntshiab? Ib tug ntshiab hlau muaj tib atoms teem nyob rau hauv tsis tu ncua txheej. … Alloys nyuaj thiab muaj zog vim tias qhov sib txawv ntawm cov atoms ntawm cov hlau sib xyaw ua rau cov atomic txheej tsis tu ncua, yog li lawv tsis tuaj yeem swb yooj yim.
Dab tsi yog qhov tsis zoo ntawm cov alloys?
Qhov qhov tsis zoo ntawm cov log tsheb yog lawv durability. Thaum muaj kev cuam tshuam los ntawm txoj kev, cov log hlau yuav zoo li khoov thiab tawg yooj yim dua li cov log hnyav dua. Lub ntsej muag zoo nkauj ntawm cov log hlau kuj tseem raug hem vim lawv yooj yim dua rau kev puas tsuaj rau tshuaj pleev ib ce.
Dab tsi yog hlau ntshiab?

Vim li cas hlau tsis tsim nyog raws li cov tub ntxhais ntawm cov hlau nplaum?
Yog cov hlau siv los ua cov tub ntxhais ntawm cov hlau nplaum, cov hlau tsis plam tag nrho nws cov hlau nplaum thaum tam sim no nres thiab nws dhau los ua cov hlau nplaum ruaj khov. Yog li cov hlau tsis siv los ua lub hauv paus ntawm electromagnet.
Vim li cas reducers yog cov haujlwm ntshiab?
Yog, ntshiab reducers yog txiav txim siab, txhais tau hais tias yog tias lawv tau txais tib lub tswv yim, lawv yuav ib txwm tsim cov txiaj ntsig zoo ib yam. Cov cuab yeej no pab nrog cov xwm txheej zoo li kev sim ntsuas, vim tias koj paub tias qhov kev xeem dhau ib zaug, nws yuav dhau mus tas li.
Vim li cas cov alloys siv hauv cov khoom siv hluav taws xob cua sov?
Raws li peb paub alloys muaj siab resistivity thiab siab melting point piv rau cov hlau ntshiab. Yog li cov hlau tsis tuaj yeem yooj yim hlawv lossis oxidize ntawm qhov kub siab dua. Tam sim no raws li peb xav kom kub siab dua hauv cov khoom siv cua sov yog li peb siv cov alloys hauv cov khoom siv cua sov.
Puas yog cov dav hlau dav hlau siv roj ntau dua?
Kev ua kom muaj zog Turboprops muaj qhov ceev tshaj plaws hauv qab 460 mais ib teev (740 km / h). Qhov no tsawg dua cov dav hlau uas siv los ntawm cov dav hlau loj niaj hnub no, txawm li cas los xij dav hlau kiv cua muaj txiaj ntsig ntau dua.
Vim li cas cov tsheb ciav hlau hluav taws xob nrawm dua li diesel?
Fais fab nroj tsuag muaj peev xwm ntau dua li ib tus neeg siv locomotive, yog li hluav taws xob locomotives tuaj yeem muaj lub zog tso zis ntau dua li cov cav tov diesel thiab lawv tuaj yeem tsim hluav taws xob ntau dua lub sijhawm luv zog. rau acceleration ceev.
