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.
