Txheej txheem Annealing
Txheej txheem annealing yog kev kho cua sovment uas siv nerooj vag tus teebmeem ntawm txias ua haujlwm that yog soften and inqob the dukev ctilityof a previkojsly lojn-hardened metal.
Kev ntxhov siab
Internal residual stressesmua develop inmetal pieces hauv teb rau zoo li yam raws li txias ua haujlwm.
Distortion thiab warpage mua result if thyog residual stresses tsis remua oved. Lawvmua eliminated los ntawm kev ntxhov siab nyem annealing tshav kub khoment nyob rau hauv uas daim yog rhuab mus tus recommxaus kojmperature, tuav
