①fokotsa ho thatafala ha tšepe, ductility e ntlafetseng, e le ho etsa hore ho be bonolo ho itšeha le ho sebetsa ha deformation a batang.

②ntlafatso ea lijo-thollo, felisa ho lahlela, forging, tjheseletsa mefokolo bakoang ke mokhatlo o hlophisitsoeng, mokhatlo o hlophisitsoeng le ho hlophisoa ha tšepe homogeneous, tšepe ho ntlafatsa tshebetso kapa bakeng sa ho latela mocheso kalafo bakeng sa ho lokisetsa dinama tse nyenyane tse.

③felisa khatello ea kelello ka hare ho tšepe ho thibela deformation le ho peperana.
