Abantu abaninzi bacinga ukuba insimbi engenasici ayinamagnethi, kwaye ihlala isebenzisa oomazibuthe ukuchonga ukuba imveliso yintsimbi engatyiwayo na. Le ndlela yokugweba eneneni ayihambelani nenzululwazi.
Insimbi engenasici inokwahlulwa ibe ngamacandelo amabini ngokwesakhiwo kwiqondo lokushisa: i-austenite kunye ne-martensite okanye i-ferrite. Uhlobo lwe-austenitic alunamagnetic okanye lubuthathaka luzibuthe, kwaye uhlobo lwe-martensite okanye lwe-ferritic lumagnetic. Kwangaxeshanye, zonke iintsimbi ze-austenitic stainless zinokuba zi-non-magnetic ngokupheleleyo kuphela kwi-vacuum state, ngoko ke ukunyaniseka kwensimbi engenasici ayinakugwetywa yimagnethi yodwa.
Isizathu sokuba insimbi ye-austenitic imagnetic: i-austenitic stainless steel ngokwayo ine-face-centered cubic crystal structure, kwaye umphezulu wesakhiwo si-paramagnetic, ngoko ke isakhiwo se-austenitic ngokwaso asinamagnetic. I-deformation ebandayo yimeko yangaphandle ejika inxalenye ye-austenite ibe yi-martensite kunye ne-ferrite. Ngokuqhelekileyo, inani le-deformation ye-martensite liyenyuka ngokunyuka kwexabiso le-deformation ebandayo kunye nokuncipha kweqondo lokushisa. Oko kukuthi, i-deformation enkulu yokusebenza ebandayo, inguqu ye-martensitic ngakumbi kwaye yomelele iipropathi zemagneti. Iintsimbi ze-austenitic ezishushu ezenziwe nge-austenitic ziphantse zingabi zimagnetic.
Imilinganiselo yenkqubo yokunciphisa ukungeneka:
(1) Ukwakhiwa kweekhemikhali kulawulwa ukufumana isakhiwo esizinzile se-austenite kunye nokulungelelanisa ukugqithiswa kwamagnetic.
(2) Ukwandisa ulandelelwano lonyango lokulungiselela izinto eziphathekayo. Ukuba kuyimfuneko, i-martensite, i-δ-ferrite, i-carbide, njl. kwi-matrix ye-austenite inokuphinda ichithwe ngonyango oluqinileyo lwesisombululo ukwenza isakhiwo sibe yinto efanayo kwaye siqinisekise ukuba ukunyanzeliswa kwamagnetic kuhlangabezana neemfuno. Kwaye ushiye umda othile ukwenzela ukuqhubekeka okulandelayo.
(3) Lungisa inkqubo kunye nendlela, yongeza ulandelelwano lonyango lwesisombululo emva kokubumba, kwaye ungeze ulandelelwano lwe-pickling kwindlela yenkqubo. Emva kokuchola, qhuba uvavanyo lwemagnethi lokungena ukuze uhlangabezane nemfuno ye-μ (5) Khetha izixhobo ezifanelekileyo zokusetyenzwa kunye nezixhobo zesixhobo, kwaye ukhethe izixhobo ze-ceramic okanye ze-carbide ukunqanda ukunyanzeliswa kwemagnethi ye-workpiece ukuba ichatshazelwe ziimpawu zemagneti zesixhobo. Kwinkqubo yomatshini, isixa esincinci sokusika sisetyenziselwa ukunciphisa ukwenzeka kokuguqulwa kwe-martensitic okubangelwa uxinzelelo olugqithisileyo.
(6) Ukuphelisa iinxalenye zokugqiba.
