Whakaritenga Whakamatau
Hei taapiri atu ki te whakarite i te hanganga matū me nga taonga miihini, ka mahia nga whakamatautau hydrostatic takitahi, ka mahia nga whakamatautau mura me te papatahi. . I tua atu, kei reira etahi whakaritenga mo te microstructure, te rahi o te witi, me te paparanga decarburization o te paipa maitai oti.
