Empilweni yansuku zonke, iningi labantu likholelwa ukuthi insimbi engagqwali ayizibuthe futhi isebenzise uzibuthe ukuyikhomba. Kodwa-ke, le ndlela ayizwakali ngokwesayensi. Okokuqala, ama-alloys we-zinc kanye nama-alloys ethuni angalingisa ukubukeka futhi askwincu ngokuswela, okuholela enkolweni eyiphutha yokuthi ingabe insimbi engagqwali. Ngisho nebanga lensimbi elisetshenziswa kakhulu elingenasici, 304, lingabonisa amadigri ahlukahlukene okubukwa ngemuva kokusebenza kubanda. Ngakho-ke, ukuncika kuphela kuzibuthe ukunquma ubuqiniso bensimbi engenasici akuthembekile.
Ngakho-ke, yini ebangela ukuba uzibuthe ngensimbi engagqwali?
Ngokokufundwa kwe-physics ebonakalayo, ubude bensimbi buthathwe ekwakhiweni kwe-elektroni. I-Electron Spin iyindawo esetshenziswayo ye-Quantum engaba "phezulu" noma "phansi." Ezintweni ezisetshenziswayo ze-ferromagnetic, ama-elektroni avumelanisa ngokuzenzakalelayo ngendlela efanayo, ngenkathi esezintweni ezilwa nama-antiferromagnetic, amanye ama-elektroni alandela amaphethini ajwayelekile, futhi ama-elekthronithi angomakhelwane ane-antiparallel spins. Kodwa-ke, ngama-elektroni emathangeni anxantathu, kumele wonke aphonswe endaweni efanayo ngaphakathi konxantathu ngamunye, okuholela ekungabikho kwesakhiwo se-net set.
Ngokuvamile, i-auntenitutic yensimbi engenasici (emelelwa ngu-304) ayikho ama-magnetic kodwa ingabikawula uMagnetism obuthakathaka. I-Ferritic (ikakhulukazi 430, 409L, 439, no-445NF, phakathi kwabanye) kanye neMartinsitic (emelelwa ngama-410) ama-steress angenazi zibuthe. Lapho amabanga angenasici afana nama-304 ahlukaniswa njenge-non-magnetic, kusho izakhiwo zawo zamandla kazibuthe ziwela ngaphansi komkhawulo othile; Kodwa-ke, amamaki amaningi angenasici abonisa iziqu zobude. Ngaphezu kwalokho, njengoba kushiwo ngaphambili, i-Auceniite ayizibuthe noma ubuthakathaka, ngenkathi uFerrite neMartensite zingama-magnetic. Ukwelashwa okushisa okungafanele noma ukuhlukaniswa kokuhlanganiswa ngesikhathi sokunyibilika kungaholela ekubeni khona kwamanani amancane ezakhiwo ezenzelwe ama-martensitic noma we-ferritic ngaphakathi kwensimbi engama-304 engenasici, okuholela ekubuthweni kobuthakathaka.
Ngaphezu kwalokho, ukwakheka kwensimbi engama-304 engagqwali kungaguqula ukufelansite ngemuva kokusebenza kubanda, futhi okubaluleke kakhulu ukuguquguquka, amafomu athe xaxa, amafomu athe xaxa, okuholela ekubutheni okunamandla. Ukuqeda ngokuphelele ubukhosi ngensimbi engama-304 yensimbi engagqwali, ukwelashwa kwesixazululo esiphakeme kungenziwa ukubuyisela isakhiwo esizinzile se-autenite.
Ngamafuphi, ukukhula kwezibuthe kwento kunqunywa njalo ngokuhleleka kwamamolekyur kanye nokuqondanisa kwe-elektroni. Kubhekwa njengempahla ebonakalayo yezinto ezibonakalayo. Ukumelana nokugqwala kwezinto ezibonakalayo, ngakolunye uhlangothi, kunqunywa ngokwakheka kwamakhemikhali futhi kuzimele ngokuzila kwayo.
Siyethemba ukuthi le ncazelo emfushane ibilokhu ilusizo. Uma uneminye imibuzo ngensimbi engenasici, sicela ukhululeke ukubheka inkonzo yamakhasimende kakhemikhali e-EST noma ushiya umyalezo, futhi sizokujabulela ukukusiza.
