Kungani 304 Ipayipi Lensimbi Engagqwali Liyizibuthe Uma Lisetshenziswa
Empilweni, sivame ukusebenzisa i-magnetism yamashubhu ukuze sahlulele ukuthi insimbi engagqwali yinhle noma yimbi, kodwa empeleni, le ndlela ayihambisani neze nesayensi. Isibonelo, ama-alloys ethu eshubhu e-zinc avamile nama-alloys eshubhu yethusi angakwazi ukulingisa ukubukeka nombala wensimbi engagqwali, futhi awawona kazibuthe, okulula ukwenziwa iphutha ngensimbi engagqwali. Ngisho nensimbi ye-304 esiyisebenzisa kakhulu okwamanje, ngemva kokusebenza okubandayo, Kuzophinde kube namazinga ahlukene we-pipe magnetism, ngakho-ke asikwazi ukwahlulela ukuthi insimbi engagqwali yinhle noma yimbi ngokuthi kukhona yini ipayipi kazibuthe. Khona-ke kungani 304 Ipayipi Lensimbi Engagqwali ikazibuthe.
Ngokuvamile, ipayipi yezimboni insimbi engagqwali ashiselwe zingahlukaniswa zibe izinhlobo ezimbili ngokusho isakhiwo salo ekamelweni lokushisa. Elinye ipayipi lensimbi engagqwali ye-austenitic, efana nepayipi elingu-304321, ipayipi elingu-316, ipayipi elingu-310, njll., kanti elinye ipayipi le-pipe martensite noma ipayipi lensimbi engagqwali ye-ferritic, njengepayipi elingu-430420, ipayipi le-410, njll. I-tubeless kazibuthe noma nge uma kazibuthe.
Sivame ukusho ukuthi i-304 insimbi engagqwali iyinsimbi engagqwali ye-non-magnetic tubular, okusho ukuthi inkomba yayo kazibuthe ingaphansi kwenani elithile. Okusho ukuthi, insimbi engagqwali ngokuvamile inezinga elithile le-tube magnetism. Insimbi engagqwali ye-austenitic eyaphakanyiswa ngaphambili ayiwona uzibuthe noma kazibuthe ebuthakathaka, kuyilapho insimbi engagqwali ye-ferritic ne-martensitic inezindawo zikazibuthe, okubangelwa ukuhlukaniswa kokwakheka noma amashubhu okwelapha ukushisa okungafanele ngesikhathi sokuncibilikiswa, Lokhu kubangela inani elincane le-martensite noma isakhiwo se-ferrite ku-austenitic 304 yensimbi engenasici, ukuze kuvele insimbi engagqwali 304. Ishubhu yensimbi engagqwali. Ngaphezu kwalokho, ngemuva kokucubungula okubandayo, ukwakheka kwe-304 yensimbi engagqwali nayo izoguqulwa ibe yi-martensite. Nge-deformation enkulu yokucubungula amashubhu abandayo, amashubhu okuguqula i-martensite ngaphezulu, amandla kazibuthe azoba namandla.
Ngakho-ke, izici kazibuthe zezinto zokwakha zinqunywa ngokujwayelekile kokuhlelwa kwamangqamuzana amashubhu kanye ne-isotropy ye-electronic spin, engathathwa njengezinto ezibonakalayo zezinto zokwakha, kuyilapho ukumelana nokugqwala kwezinto kunqunywa ukwakheka kwamakhemikhali wezinto zokwakha, okuyizinto zamakhemikhali zezinto zokwakha namashubhu, futhi akuhlangene nokuthi izinto zikazibuthe noma cha.
