Ntxiv rau kev ua kom ntseeg tau tias muaj cov tshuaj lom neeg thiab cov khoom siv kho tshuab, kev ntsuam xyuas hydrostatic raug ua ib qho los ntawm ib qho, thiab kev ntsuam xyuas flaring thiab flattening raug ua. . Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, qhov loj me ntawm cov noob, thiab txheej decarburization ntawm cov yeeb nkab hlau tiav.
