Quenching cools lub sab nrauv ntawm iav ntau sai dua qhov chaw. Raws li qhov nruab nrab ntawm lub khob txias, nws sim rub rov qab los ntawm qhov chaw sab nrauv. Raws li qhov tshwm sim, qhov chaw tseem nyob hauv qhov nro, thiab cov chaw sab nrauv nkag mus rau hauv compression, uas muab cov iav tempered nws lub zog.
Vim li cas tempered iav muaj zog dua?
Tempered iav yog li plaub npaug zog dua li cov iav annealed. … Raws li qhov tshwm sim ntawm qhov kev ntxhov siab ntau ntxiv, thaum tawg lub iav tawg rau hauv me me sib npaug chunks as opposed to sharp jagged shards. Compressive deg stresses muab tempered iav muaj zog.
Vim li cas cov iav tempered muaj zog dua li iav ib txwm?
Tempered iav yog li plaub npaug zog dua li cov chav kawm ib txwmthiab paub txog nws txoj kev nyab xeeb. Thiab, tsis zoo li cov iav niaj hnub, tempered iav tawg ua rau me me, tsis muaj teeb meem. Qhov no yog ua tau vim hais tias thaum lub sij hawm annealing cov iav yog txias cia, uas ua rau lub iav muaj zog ntau.
Puas yog iav tempered muaj zog tshaj?
Tempered muaj zog dua . Tempered iav muaj qhov tsawg kawg nkaus ntawm qhov compression ntawm 10,000 phaus-ib-square-inch (psi) thiab qhov tsawg kawg nkaus ntug compression ntawm 9, 700 psi, raws li ASTM C1048. Qhov ntawd ua rau nws muaj zog dua li plaub npaug ntawm cov iav annealed.
Vim li cas tempered iav tawg yooj yim?
Kev tawg ntawm cov iav tempered feem ntau yog tshwm sim los ntawmchipped lossis nicked npoo thaum lub sijhawm teeb tsa, kev ntxhov siab tshwm sim los ntawm kev khi rau hauv lub thav duab, sab hauv tsis xws luag xws li npib tsib xee sulfide inclusions, thermal stresses nyob rau hauv lub khob, thiab tsis txaus thickness tiv thaiv siab cua loads.
