Duplex simbi isina tsvina, ine mukurumbira nekubatanidzwa kwayo kwe austenitic uye ferritic hunhu, inomira sechiratidzo chekushanduka kwesimbi, ichipa mubatanidzwa wemabhenefiti uku ichidzikisa zvipingamupinyi zvemukati, kazhinji pamutengo wemakwikwi.
Kunzwisisa Duplex Stainless Simbi:
Pakati pekukosha kwe duplex simbi isina simbi ndeye mbiri-chikamu microstructure, inowanzo sanganisira musanganiswa wakaenzana we austenite uye ferrite, ichipa symbiosis yehunhu hwakanaka uku ichideredza kusasimba. Iyo metallurgical kuumbwa, kunyangwe inoenderana negiredhi chaiyo, inowanzo batanidza kabhoni, manganese, silicon, chromium, nickel, phosphorus, uye sarufa, ine sarudzo yekuwedzera senge molybdenum, nitrogen, uye mhangura inowedzera kunatsa zvinhu zvezvinhu.
Historical Context yeDuplex Stainless Steel:
Iyo genesis ye duplex stainless alloys inoteedzera kumashure edzidziso musings muma1920s, ichiguma neanobatika mabhindauko ekugadzira mukati ma1930s. Pakutanga yakaganhurirwa kugadzira kugadzirwa uye mashandisirwo akasarudzika nekuda kwekukwira kwekabhoni yemukati, kufambira mberi mukuita decarburization mukupera kwema1960 kwakazivisa nguva nyowani, kufambisa kubatanidzwa kweakaderera-kabhoni alloys ane yakagadziridzwa chromium uye nickel zvemukati, nekudaro kunatsa chiyero pakati peferrite uye austenite. Mucherechedzo weiyi shanduko yekushanduka-shanduka ndeye Duplex 2205, alloy yekupayona kubva pakati pe-1970s inoramba ichiraira kukosha nekuda kweiyo yepamusoro corrosion kuramba vis-à-vis yakajairwa austenitic mamakisi.
Zvakanakira zveDuplex Stainless Steel:
Kunyangwe ichiumba chikamu chine mwero chemusika wesimbi isina simbi, duplex alloys anopa huwandu hwezvakakodzera vis-à-vis yechinyakare austenitic uye ferritic vamwe. Chinocherechedzwa pakati peaya mabhenefiti akawedzera kusimba, kusimba kwakawedzera, uye ductility, nekuora kwekuramba kuri kubuda sechiratidzo chechiratidzo, kukwikwidza, kana kusapfuura, iyo yeaustenitic mamakisi. Zvakare, iyo mutengo-inoshanda inogara mu duplex simbi, nekuda kwekushandisa zvine hungwaru kwezvinhu zvinosanganiswa, zvinoipa sarudzo inogombedzera kune akasiyana siyana maapplication.
Zvishandiso zveDuplex Stainless Steel:
Iko kuita kwakasiyana-siyana kwe duplex simbi isina tsvina kunowana resonance kune akatevedzana maindasitiri nemadomasi, nekuda kweiyo stellar corrosion kuramba, simba rakawedzerwa, uye hunhu husingadhuri. Kunyanya, mashandiro ekumahombekombe uye padyo nemahombekombe, anosanganisira kuchera oiri, kubvisa munyu, uye kuchenesa mvura, zvinomira sevabatsiri vepamusoro pakugona kwe duplex simbi. Saizvozvo, kushandiswa kwayo kunosvika pakugadziriswa kwemakemikari, zvikumbiro zvemugungwa, michina yekudzora kusvibiswa, uye mabasa ekuvaka, zvichisimbisa kuvepo kwayo kwese munzvimbo dzemazuva ano maindasitiri.
