Momwe mungaletsere mapindikidwe a forgings pa kutentha mankhwala

Ena forgings amafuna kutentha mankhwala pambuyo kutentha ndi forging. Pa kutentha mankhwala, tcherani khutu kuchepetsa njira ndi chiwerengero cha magawo masungidwe. Chimodzi ndicho kupachika molunjika momwe mungathere. Malowa ali pakati pa gawo limodzi mwa magawo atatu ndi gawo limodzi mwa magawo atatu a utali wonse, ndipo wachinayi akugona pansi pa zida zachitsulo zosagwira kutentha. Kuyika kolakwika ndi chimodzi mwa zifukwa za deformation.

Kachiwiri, mtundu wa kuziziritsa ndi kuzimitsa sing’anga mu kutentha kutentha, ntchito kuzirala, palibe kusankha kapena ntchito molakwika zonse zikugwirizana ndi kuumitsa deformation. Kusintha kwa ntchito kuzirala kungasinthidwe ndi kusintha mamasukidwe akayendedwe, kutentha, madzi pamwamba kuthamanga kwa sing’anga, ntchito zina, oyambitsa, etc. The apamwamba mamasukidwe akayendedwe a quenching mafuta ndi apamwamba kutentha, ang’onoang’ono mapindikidwe elliptical. Mu mpumulo, deformation ndi yaying’ono.

Komanso, kulabadira kutentha kusintha mphamvu quenching pa kutentha mankhwala. The quenching kutentha ndi mafuta utakhazikika kutentha pang’ono kuposa Ms mfundo, ndiye mwamsanga ndi anakhalabe mu mlengalenga kupanga lonse kutentha kwa mbali yunifolomu, ndiyeno mafuta-utakhazikika kupanga martensitic kusintha yunifolomu. Kusakhazikika kwa deformation kumakula kwambiri.
