Kev npaj ntawm Tempered iav

Tempered iav yog tau los ntawm kev txiav cov iav annealed zoo tib yam rau hauv qhov yuav tsum tau ua, cua sov rau ib ncig ntawm 700 degrees nyob ze ntawm lub softening point, thiab ces sai thiab uniformly txias nws (feem ntau yog 5-6 hli iav yog rhuab rau li 240 vib nas this thiab txias rau li ntawm 150 vib nas this ntawm qhov kub ntawm 700 degrees. lub thickness ntawm iav). Tom qab tempering, uniform compressive kev nyuaj siab yog tsim nyob rau saum npoo ntawm lub khob, thaum tensile kev nyuaj siab yog tsim nyob rau hauv, uas pab txoj kev khoov thiab cuam tshuam lub zog ntawm lub iav. Nws lub zog yog li plaub npaug siab dua li ntawm cov iav annealed zoo tib yam. Tempered iav uas tau tempered thiab ua tiav tsis tuaj yeem txiav ntxiv, hauv av, lossis puas, txwv tsis pub nws yuav raug crushed rau tej daim vim tsis ua hauj lwm ntawm kev sib npaug compressive kev nyuaj siab.
