Ukupholisa kweukuthethelelwakubhekiswa ukupholisa kusuka ekushiseni kokugcina kokushisa kokushisa kwegumbi ngemuvaukuthethelela. Uma indlela yokupholisa ingakhethwa kahle,ukuthethelelwaKwangathi kungavulwa ngenxa yokuqhekeka noma amabala amhlophe, futhi ukukhiqiza kungathinteka ngokunweba umjikelezo wokukhiqiza. Ngakho-ke,ukuthethelelaukupholisa nakho kuyisixhumanisi esibalulekile ngaphakathiukuthethelelaukukhiqiza. Ukuthethelela ukucindezelwa kwangaphakathi kwinqubo yokupholisa: I-billet izokhiqiza ingcindezi yangaphakathi kwinqubo yokushisa, kanyeukuthethelelaKuzobuye kubangele ukucindezela kwangaphakathi kwinqubo yokupholisa. Ngobaukuthethelelwazisesimweni sokunwebeka ngokushisa okuphansi esikhathini sokupholisa kamuva, ingozi yokupholisa ukucindezela kwangaphakathi kwangaphezu kwaleyo yokushisa ukucindezela kwangaphakathi. Ngokwezimbangela ezahlukahlukene zokuxineka kwangaphakathi ngesikhathi sokupholisa, kukhona ukucindezelwa kwezinga lokushisa, ukucindezelwa kwezicubu kanye nokuxineka kwezicubu.

1. Ukushisa okushisa okusesigabeni sokuqala seukuthethelelaUkupholisa, indawo epholile ebusweni ngokushesha, ivolumu enkulu yevolumu; Ukupholisa komongo kuhamba kancane kanti ivolumu liyancipha. Njengoba i-shrinkage ebusweni ivinjelwe yinhliziyo, ukucindezela kwezinga lokushisa kukhiqizwa ngaphakathi kwecala, ingaphezulu yingcindezi ebusayo, futhi inhliziyo icindezelwe. UmaukuthethelelaIzinto ezibonakalayo ziyinsimbi emnene ngokumelana okuncane kanye nokonakala okulula, ngokuphola okuqhubekayo, ukucindezela okuthe xaxa okwenziwe ebusweni ekuqaleni kokuphola kancane kancane. Esigabeni sakamuva sokupholisa, izinga lokushisa elingaphezulu liphansi kakhulu, futhi ivolumu shrinkage lima, ngenkathi ivolumu yevolumu eliyisisekelo livinjelwe ungqimba olungaphezulu. Ngenxa yalokhu, ushintsho lwezimo zokushisa lokushisa, ungqimba olungaphezulu luba ngcindezi olucindezelayo, futhi umnyombo uba ngcindezi. Uma i-hard yensimbi yokwazisa izinto zokumelana nokuzenzisa okukhulu, ekuqaleni kobuso obupholile bokucindezela okuthe xaxa ngeke bukwazi ukuphumula ekucindezelekeni kwengcindezi, futhi kungadala ukunciphisa ukucindezelwa kwezimpawu, futhi kungabingelwa ukucindezelwa okuthe xaxa, inhliziyo isesekucindezelwe okuthe xaxa. Ngakho-ke, ukuthethelelwa kwensimbi emnene kungahle kubonakale ukuqhekeka kwangaphakathi lapho kuphola, futhi ukuthethelelwa kwensimbi enzima kulula ukukhiqiza ukuqhekeka kwangaphandle lapho kupholisa.

2. Ukucindezela kwenhlanganoukuthethelelwaEnqubweni yokupholisa, njengokuguqulwa kwesigaba, ngaphezu kokudala ukucindezelwa kwezingathwa, kuzothuthukisa ukucindezela kwenhlangano, nakho kungenxa yokushintshwa kwenguquko yenhlangano ngaphambi nangemva kwesikhathi sokuguqulwa kwesigaba, kanye nomphumela wesigaba sokuguqulwa esigabeni setafula. Njengokuthingela ekwenzeni inqubo epholile yokuguqulwa kweMferensi, ngokushisa kokuthethwa kwehlisiwe, ingaphezulu lokuguqulwa kweMferensi, ngenxa yethamo elithile leMfembu likhulu kunengcindezi elicindezelayo, inhliziyo inengcindezi ecindezelekile. Kepha ngalesi sikhathi, izinga lokushisa eliyisisekelo liphezulu, endaweni enhle ye-Auucenite yasePustic, ngokuguquguquka kwepulasitiki yendawo, ukucindezelwa okungenhla kuvuselelwa ngokushesha. Lapho-ke ukucekelwa phansi kupholile, ukuguqulwa kweMartensitic kwenzeka enhliziyweni, khona-ke ingcindezi yenhlangano, inhliziyo iyingcindezi ecindezelayo, ungqimba olungaphezulu lungcindezi. Ukucindezela kuyakhuphuka kuze kube yilapho ukuguqulwa kweMfethuni sekuqediwe. Njengoba ivolumu ethile yazo zonke izigaba ensimbi inkulu kunaleyo ye-Aucen, ingcindezi yemvelo ekhiqizwa ezinye izinguquko ezengeziwe ngesikhathi sokupholisa kokupholisa futhi inomthetho ongenhla.
Ingcindezi engu-3.ResidaalukuthethelelwaEnqubweni yokwakha, ngenxa yokuguqulwa okungalingani kokucindezelwa kwangaphakathi okubangelwa ukuqina komsebenzi, okunjengokuphela kungaba ngcono kabusha okuthambisa ukuthambisa ukuqeda, ngemuvaukuthethelelauzoba yingcindezi eyinsalela. Ukusatshalaliswa kwengcindezi eyinsalela ekuthetheleleni ngaphakathi kweqembu lesimemezelo ngokuya ngokungcola okungalingani eqenjini le-Declaration. Kungaba ukucindezela okuthe xaxa ebusweni nasekucindezelekeni okucindezelayo enkabeni, noma okuphambene nalokho. Kuyabonakala ukuthi kunezinhlobo ezintathu zezingcindezi zangaphakathi ezishiwo ngenhla kwinqubo yokupholisa ngemuvaukuthethelela, futhi ukucindezelwa kwangaphakathi okuphelele kukhulu kakhulu yilezi ezintathu. Lapho inani lokucindezela eliphakeme lidlula umkhawulo wamandla, lizodala ukuqhekeka ezingxenyeni ezihambisanayo zeukuthethelela, ukuqhekeka okupholile kuvame ukwenzeka lapho izinga lokushisa liphansi futhi i-plasticity imbi :. Njengokuphakama kwengcindezi yangaphakathi akuzange kubangele ukulimala, kuzogcinwa ukuphela kokupholisa, kwaziwa ngokuthi ukucindezelwa okusele kokuthethelela.
