Inkcazelo emfutshane:

Emva kokuhamba nge-forging, isakhiwo sesinyithi kunye nepropati yayo yomatshini inokuphuculwa. Ikristale enkulu yoqobo kunye neprismatic crystal grain iba yincinci kwaye incinci ngokulinganayo, emva koko ilungelelaniswe kwakhona ukwenza i-a-liquation, i-looseness, i-bubble yomoya kunye ne-slag efakiweyo icinezelwe kwaye isakhiwo sayo sisondele kwaye siqinile esiphucula iplastiki kunye nepropathi yomatshini yesinyithi. Kodwa ipropathi yomatshini yeqhekeza lokuphosa libi kunelinye iqhekeza lezinto ezifanayo. Ngaphandle koko, ukubumba kunokuqinisekisa ukuqhubeka kolwakhiwo lwefayibha yesinyithi kunye nokugcina ulwakhiwo lwefayibha kunye nemilo yangaphandle iyafana, ukuhanjiswa kwesinyithi kugqibelele kwaye kuqinisekise ixesha elide lobomi kunye nepropathi elungileyo yoomatshini. Ubuchwephesha bokusebenzisa ukubumba okuchanekileyo. ucinezelo olubandayo, ucinezelo olufudumeleyo alunakuthelekiswa nanto ekwenzeni iqhekeza lokubumba.
