Kutentha mankhwalandi imodzi mwazinthu zofunika kwambiri popanga njira yopangira kufa, yomwe imatenga gawo lalikulu pa moyo wakufa. Malinga ndi zofunikira zenizeniukadaulo wopanga, teknoloji yopangira kutentha kwapangidwa kuti ipangitse mphamvu (kuuma) kwa nkhungu yofanana bwino ndi kuuma, kuuma kwa thupi la nkhungu ndi nkhungu yonyezimira ndi yololera komanso yunifolomu, njere ndi yabwino komanso yunifolomu, palibe makutidwe ndi okosijeni ndi decarburization, kuchepetsa nkhawa yotsalira ndi mapindikidwe, zomwe zingathe kusintha moyo ndi kukhazikika kwa nkhungu. Kugwiritsa ntchito ukadaulo watsopano wochizira kutentha kumatha kukhudza zomwe zingatheke ndikuwongolera kwambiri moyo wa nkhungu pamtengo wocheperako. Mwachitsanzo, kwa high-carbonkusuta fodya kumafa, kugwiritsa ntchito kuzimitsa kutentha pang'ono kuti mupeze lat Martensite yambiri kumatha kulimbitsa mphamvu, kuchepetsa kuwonongeka kwa nkhungu ndi kuzimitsa mng'alu, motero kumapangitsa moyo wa nkhungu kukhala wabwino. Chithandizo cha kutentha kwa vacuum chimakhala ndi zabwino zopanda oxidation, decarburization, degassing, kutentha kwa yunifolomu ndi mapindikidwe ang'onoang'ono, zomwe zimapindulitsanso kukonza moyo wakufa.

Zotsatira za mankhwala pamwamba pa kulimbikitsa pamwamba nkhungu anabala ndi kuonjezera moyo nkhungu si zodabwitsa, komanso mtengo wotsika. Wagwiritsidwa ntchito ndipo ali ndi ntchito zomwe zingagwiritsidwe ntchito pa nkhungu pamwamba pa kulimbikitsana kwa njira yopangira mankhwala ali ndi mapindikidwe (kuwombera, kupukuta, kutuluka ndi kupukuta, etc.) kulimbitsa, kulimbitsa kusinthika kwapamwamba, kulimbikitsa kuwonjezereka kwapamwamba ndi kulimbitsa ion implantation, kuyika mpweya wakuthupi ndi matekinoloje osintha pamwamba monga makina opangidwa ndi membrane, electrochemical deposition, electrochemical deposition, electrochemical deposition. Kupopera mbewu mankhwalawa matenthedwe zokutira.
