③ Isi metotia fa'avasegaga

E tusa ai ma le vevela deformation, forging e mafai ona vaevaeina i le vevela vevela (faʻagaioiga vevela e maualuga atu nai lo le recrystallization vevela o le uʻamea pili), mafanafana mafanafana (i lalo ifo o le recrystallization vevela), ma malulu forging (i le potu vevela).
