Kulondolamaziko a nkhunguimasungabe austenite pang'ono yotsalira ndipo imatha kumasula kupsinjika ngati pakufunika, komwe kumakhala ngati chitetezo. Chifukwa chotsalira cha austenite ndi chofewa komanso cholimba, chimatha kuyamwa pang'ono mphamvu yakukulirakulira kwa martensite ndikuchepetsa kupsinjika kwakusintha; kuchichotsa pambuyo mankhwala ozizira Kuikamaziko a nkhungum'madzi otentha kutenthetsa akhoza kuthetsa 40% -60% ya kuzizira mankhwala nkhawa. Pambuyo kutenthetsa kutentha kwa firiji, ziyenera kuchepetsedwa mu nthawi kuti mupitirize kuthetsa kupsinjika kwa mankhwala ozizira, kupewa mapangidwe a ming'alu ya mankhwala ozizira, kupeza katundu wokhazikika wa minofu, ndikuonetsetsa kuti nkhungu zoyambira zimasungidwa ndikugwiritsidwa ntchito. Palibe kupotoza kumachitika.
