Uhlobo lwe-auntenitic alunazibuthe noma ubuthakathaka kazibuthe noma obuthakathaka, futhi i-martensite noma i-ferrite yi-magnetic.
Ama-scaffold ajwayele ukusetshenziswa njengamashidi we-tube wokuhlobisa iningi lezinto zokwenziwa ze-auntenitic 304, ezingezona ezingezona izibuthe noma zobuthakathaka. Kodwa-ke, ngenxa yokushintshashintsha kwezakhi zamakhemikhali noma izimo ezihlukile zokucubungula ezibangelwa ukunyibilika, kungenzeka futhi izakhiwo, kepha lokhu ngeke kubhekwe njengesizathu sokungafanele noma singafaneleki?
Ngenxa yokwahlukaniswa kwengxenye noma ukwelashwa okungafanele kokushisa ngesikhathi sokunyibilika, inani elincane lesakhiwo se-martensite noma se-ferrite ku-aucenite 304 Scaffold zizobangelwa. Ngale ndlela, kuzoba nobuthakathaka obubuthakathaka kuma-scaffolds angama-304.
Futhi, ngemuva kokuthi ama-scaffoldings angama-304 asebenza kubanda, isakhiwo sizoguqulwa sibe ngumfemuni. Lapho likhudlwana izinga lokukhubazeka okubandayo okubandayo, ukuguqulwa okwengeziwe kwe-Martenses kanye ne-Magnetic Properties yensimbi. Njenge-batch yemichilo yensimbi, Φ76 Kukhiqizwa amashubhu ngaphandle kokungeniswa kwamandla kazibuthe, kanye Φ 9.5 Kukhiqizwa amashubhu. Ngoba i-defformation ebhulayo ikhulu, ukungeniswa kwamandla kazibuthe kusobala kakhulu, futhi ukuguquguquka kwe-tube yesikwele kukhulu kunalokho kweshubhu eliyindilinga, ikakhulukazi ingxenye enkulu futhi ukhula lusobala kakhulu.
Ukuqeda izakhiwo zamazibuthe zamashidi angama-304 ensimbi ezibangelwa yizizathu ezingenhla, isakhiwo se-Auucenite singabuyiselwa futhi sizinziswe ngokwelashwa okushisa okuphezulu, ngaleyo ndlela kuqede izakhiwo ezibucayi. Ikakhulu, ubusika obungubuthendeli obubangelwa yizizathu ezingenhla abukho ezingeni elifanayo nokuzibuthe kwezinye izinto, njengensimbi ka-430 ne-carbon, okusho ukuthi uzibuthe amashidi angu-304 wensimbi uhlala ekhombisa ukhula olubuthakathaka njalo.
Lokhu kusitshela ukuthi uma i-scaffold ibuthakathaka kazibuthe noma hhayi uMagthetic, kufanele yahlulelwe njengento engama-304 noma 316; Uma kufana nensimbi yekhabhoni, kukhombisa ubude obunamandla, ngoba lekwahlulelwa njengezinto ezingaba ngu-304.
