Ukuhlaziywa kwemishini yokuzijabulisa kwe-crack kusizakala ukwazisa isizathu esibalulekile sokuqhekeka, okuyinto eyisisekelo senhloso yokuhlonza. Ingabonakala kusuka ekuhlaziyweni kwamacala amaningi okuqhekeka kanye nokuhlolwa okuphindaphindiwe okuthi indlela kanye nezimpawu zokwenziwa kwensimbi ye-alloy akunangqondo, okunokulimala okusemqoka kokuqhekeka.

Kuyo yonke inqubo yokuguqulwa, ukusabeka ukuzivocavoca endizeni eshelelayo, futhi lapho ihlangana nokuvinjwa komgwaqo, iyobumba futhi ibambe ukucindezelwa okwenele komhlaba, noma i-cavital kanye nemifantu emincane ngenxa inkambiso yentuthuko yemifantu yezomnotho macro. Le miphumela ebalulekile ekushiseni kwe-defformation iphansi (ephansi kunomshini wokushisa wokuqina), noma izinga lokukhubazeka likhulu kakhulu, izinga lokukhubazeka lishesha kakhulu. Lolu hlobo lokuqhekeka luvame ukuvame ukwehluleka noma ukwehlisa okwenziwe ngokwethulayo kanye nokwehla kwezingalo, kepha ngoba ama-molecule aphezulu okushisa anezinga langaphandle, asheshise ukulungiswa kokulungiswa, ukuze inqubo yokwehla isivele idale ama-micro I-Crack kulula ukuyilungisa, ekushiseni kwe-defformation efanelekile, izinga lokukhubazeka liyisimo esisheshayo, asikwazi ukuthuthukisa umkhuba wokuqhekeka kwama-macroeconomic.

Ukuze izinto zokwakha nezindlela ze-asymmetrical kanye nezakhiwo, ukuqhekeka ngokuvamile kwenzeka emingceleni yokusanhlamvu namanye amakhasi esigaba. Lokhu kungenxa yokuthi i-deformation evuzayo iyenziwa ngokuvamile ukuzungeza amazinga okushisa alinganayo ezinto zensimbi. Ukuguqulwa komngcele wokusanhlamvu kukhulu kakhulu, ngakho-ke umngcele wokusanhlamvu wezinto zensimbi ububi bemikhakha ye-metallurgical, isigaba sesibili nezinto ezingezona zensimbi zigxiliwe endaweni. Emazingeni okushisa aphezulu, amakhemikhali aphansi we-solubity point emingceleni yokusanhlamvu yezinto ezithile ezingavuthiwe akhiqiza ukuncibilika, okuqinile

Ukunciphisa ukuphuma kwepulasitiki kwezinto eziluhlaza; Ekushiseni okuphezulu, ezinye izinto (isibabule, ithusi, njll.) Ezintweni ezizungezile zisetshenziswa emngceleni wokusanhlamvu kuya ngaphakathi nangaphandle kwezinto zensimbi, okuholela ekubonakaleni komngcele wesibili kanye nokuncipha komngcele wokusanhlamvu . Kokunye, izinto ezijwayelekile zensimbi zinobudlelwano obumpofu ngezigaba ezithile ngenxa yokwehluka kwezindawo ezingokomzimba nangamakhemikhali zezigaba ezimbili.

Izinto ezisetshenziswayo ezivame ukusetshenziswa ejele ngokuvamile azivumelani ngokulinganayo. Ngakho-ke, ukuqhekeka kothethelelwa kwamahhala kwenzeka futhi kuthuthukiswa emngceleni wokusanhlamvu noma umngcele wesigaba ngesikhathi sokushisa okuphezulu.
