Ingcindezi ephezulu ye-alloy pope aqinisayo iqinisa ukusetshenziswa kwendlela yokuguqulwa kokuqiniswa kwensimbi. Owaziwa nangokuthi yi-strain qinisa noma usebenze kanzima. Amandla okuqukethwe kuma-macro (noma awonke) amandla okumelana noshintsho (noma ukugeleza kwengcindezi). Ubulukhuni yikhono lezinto ezibonakalayo ukumelana noshintsho lwepulasitiki olwenziwe lwasendaweni (kungaba bulukhuni, ubulukhuni bamaviki, ubulukhuni be-rockwell noma ubulukhuni be-brinell). Zombili zinobuhlobo obufanayo obuhambisanayo ezimweni eziningi. Amandla wezinto ezibonakalayo, kukhula okukhulu ekuguqukeni kwepulasitiki, kukhuphuka inani lobulukhuni. Ngakolunye uhlangothi, kuphakama ubulukhuni balokho okuqukethwe, okuqukethwe kungenzeka kube khona ngenxa yokwenyusa ubucwebe, amandla alo akuboniswa ngokuphelele kunani lenkomba yamandla aliphezulu.
Ukuze uthole isikhathi eside ukwelashwa kokushisa, kanye nokusetshenziswa kwezinto zokushisa ngaphansi kwezinga lokushisa eliphindaphindwayo le-Alloy Pipe Free Pipe okuqukethwe (njengensimbi ephansi ye-carbon low-alloy) ukuze kusetshenziswe amandla okuqina ukuze uqinise amandla. Ngakho-ke, isimo sokuqinisa defformation sikushisa kakhulu kokushisa okuphindaphindiwe kokuqukethwe okubandayo okubandayo, okubangelwa ukwehla kwamandla (okuholela ekuchithekeni okuphezulu kwekristalu, kukhuphuka ukuncibilikisa ukungcola ku-crystal, kukhuphuka kakhulu ukuthuthumela, okungukuthi i-expression ephezulu yokuthuthuka. Ngemuva kokucindezela kokugeleza kwensimbi akufanele kulingane ngaphambi kokugeleza kokugeleza kwe-defformation flow kanye nokuqina okuqinisa ukugeleza kokugeleza kokuguquguquka. Ukusetshenziswa kokuqina kokuqinisa ukuzuza ukufeza imikhiqizo yensimbi ephezulu, okujwayelekile yintambo yensimbi ebandayo yensimbi ebandayo kanye ne-carbon low-alloy duple elibandayo lensimbi ebandayo.
Ngokukhuphuka kwezinga lezenkolo, amandla abonakalayo kanye nobulukhuni obuphakeme kakhulu kanye nokuphakama, kepha ukuhlehlisa kwawo kuvame ukuthola okuphansi nangaphansi, okudinga ukuthi kunzima ukuthatha izinyathelo ezifanele zokuthuthukisa isimo. Isigaba sangaphakathi esisesigabeni se-Martensitic esiguqukayo ukupholisa kokuqina, ngokwenyama yaso ngokomzimba, futhi kungokwesikhundla sokukhubazeka, kepha lesi sikhathi hhayi ekuguqukeni kwangaphandle, kepha inqubo yenguquko ye-martensitic kusuka endaweni ye-Crystal High-density ngokwayo ikhiqizwe ngephutha.
