Yuav tiv thaiv iav tawg li cas

Thaum peb siv iav, peb yuav ntsib qhov teeb meem ntawm iav tawg ib ntus, thiab peb tsis paub tias vim li cas ntawm qhov tawg. Niaj hnub no, peb xam phaj ib tug kws kho mob hauv lub Hoobkas iav. Raws li nws, yog vim li cas rau lub iav tawg yog tias lub iav yog ib tug tsis zoo conductor ntawm tshav kub. Thaum lub khob tso rau sab nraum zoov thaum txias, cov phab ntsa sab nrauv yuav txo qis sai, thaum lub khob sab hauv ntawm lub khob tsis shrunk sharply, ua rau lub khob tau rhuab tsis sib xws thiab tawg.

Siv iav nyob rau lub caij ntuj no, tsuas yog ib qho uas yuav tsum tau them sai sai rau yog tias iav feem ntau ntshai ntawm thermal expansion thiab contraction, qhov kub ntawm lub iav yog qis heev (xws li tsuas yog coj tawm ntawm lub tub yees, tsuas yog coj los ntawm qhov txias sab nraud. , tsis txhob muab dej kub tam sim ntawd, thaum kuv tawg tas, thaum kuv nchuav dej tas, lub khob tawg tas, ua rau cov dej kub ntws los rau hauv kuv lub cev.

Qhov no muaj feem xyuam rau cov txheej txheem ntawm cov iav, cov khoom siv iav niaj hnub yuav tsum dhau los ntawm cov txheej txheem annealing thiab tempering, annealing yog tshem tawm cov kev ntxhov siab sab hauv hauv cov txheej txheem iav, tempering yog ua kom cov iav tawg mus rau hauv cov khoom me me. zam kev raug mob. Yog tsis muaj annealing, kev ntxhov siab nyob rau hauv lub khob tsis zoo tshem tawm, yooj yim heev rau tawg, qee zaum tsis xav tau sab nraud quab yuam, lawv yuav tawg.

Yog li ntawd, peb qhia rau koj ntxiv, thaum siv lub khob rau lub caij ntuj no, ntau dua los yog tsawg dua ncuav rau hauv dej sov me ntsis, kom lub khob kom sov sib npaug, thiab tom qab ntawd ncuav hauv dej npau npau. Txhawm rau tiv thaiv cov iav los ntawm tawg, yog li ntawd, tib neeg yuav tsum tau saib xyuas.
