Xa uthelekisa i-iron yentsimbi kunye ne-ductile yentsimbi, kubalulekile ukuba uqonde ukuba ngelixa zombini ziziintlobo ze-iron, zinepropathi ezahlukileyo kwaye zilungele izicelo ezahlukeneyo. Nantsi Thelekisa iinkcukacha:
1. Ubume bezinto ezibonakalayo kunye nolwakhiwo
Isinyithi esisengqiqweni sentsimbi:
Ukuqulunqwa:Isinyithi esingenzisidengeyenziwa bubushushu-i-Iron emhlophe eqhinqelweyo, equlethe ikharbon ngendlela yentsimbi ye-iron carbide (FE3C). Unyango lobushushu, olwaziwa ngokuba lulolo, luqhekeze i-carbide yentsimbi, ivumela i-carbon ukuba ibe yigrafu kwifom yomdyuli okanye yeRosette.
Ulwakhiwo: Inkqubo yokwazi itshintsha ubume bentsimbi, ngenxa yamasuntswana amancinci, angahambelani nolingane. Olu lwakhiwo lubonelela ngezinto ezinokuqina kunye nobunzima, zenza ukuba zibe yi-brittle kune-iron yemveli.
Intsimbi yentsimbi:
Ukuqulunqwa: Intsimbi yentsimbi, ekwabizwa ngokuba ngumkhweli okanye i-spheroid i-iron yegrafu, iveliswa ngokongeza izinto ezingekho mthethweni njenge-magnesium okanye i-cirium ye-ferium yokuphosa i-iron. Ezi zinto zibangela ukuba ikhabhoni ibe yeyokwenza i-spheroid (i-Round) i-graphles.
Ulwakhiwo: Ubume begrafikhi ye-Spherite kwi-guctile intsimbi iphucula indlela yayo kunye nokungaxhathisi bempembelelo, ukunika iipropathi ezibalaseleyo zoomatshini xa kuthelekiswa nentsimbi enokufikisa.
I-2. Iipropathi zoomatshini
Isinyithi esisengqiqweni sentsimbi:
Amandla amanxuwa: Isinyithi esibi senziwe sinamandla amanye amanxuwa, esiqhelekileyo ukusuka kwi-350 ukuya kwi-450 MPA (megapascals).
I-DECTIT: Inendawo efanelekileyo, evumela ukuba igobe okanye ichaphazele phantsi koxinzelelo ngaphandle kokuqhekeka. Oku kwenza ilungele ukusetyenziswa apho kufuneka ubhekiso.
Ukunganyangeki kwempembelelo: Ngelixa kuqinisekiswe kunemveli yemveli, i-Irling yentsimbi engenangqondo ichaphazela i-iron enganyangekiyo kwintsimbi ye-ductile.
Intsimbi yentsimbi:
Amandla obuzinile: Intsimbi ye-Ductile inamandla aphezulu amanye, ihlala isusela kwi-400 ukuya kwi-800 MPA, kuxhomekeke kwibanga kunye nonyango lobushushu.
I-DECTIT: I-Deperile kakhulu, inepesenti ye-elongwation eqhelekileyo phakathi kwe-10% ne-20%, intsingiselo iyolule kakhulu ngaphambi kokuphela kwento.
Ukunganyangeki kwempembelelo: Intsimbi ye-Ductile yaziwa ngokuba kukungaxhathisi
3. Izicelo
Isinyithi esisengqiqweni sentsimbi:
Ukusetyenziswa okuqhelekileyo: Intsimbi enobungozi idla ngokusetyenziswa kwiindawo ezincinci, ezingathandekiyo ezifana nemibhobho, iibakaki, kunye nezixhobo zokusebenza apho kufuneka amandla kwaye kuyafuneka khona.
Indawo eqhelekileyo: Iqhelekile isetyenziselwa ukwenza imibhobho, imibhobho yegesi, kunye nezicelo zokukhanya kwemveliso. Ukukwazi kwezixhobo zokufumana ukothuka kunye needrafti kwenza ukuba kuqinisekiswe ufakelo olubandakanya ukuhamba koomatshini okanye ukwanda kwe-thermal.
Intsimbi yentsimbi:
Ukusetyenziswa okuqhelekileyo: Ngenxa yamandla ayo aphezulu, i-ductile yentsimbi isetyenziswa kwizicelo ezikhulu nezifuna izinto ezinokufunwa njengezixhobo zemoto (umz.
Indawo eqhelekileyo: Intsimbi ye-ductile ilungele ukusetyenziswa kwimibhobho yoxinzelelo oluphezulu, iinkqubo zamanzi kunye neenkqubo zokuntywila, kunye neemeko apho izinto ziphantsi koxinzelelo olubalulekileyo okanye impahla.
Ukuqukumbela
I-iron enesitokhwe kunye nentsimbi ye-ductile ayifani. Ziintlobo ezahlukileyo zentsimbi ye-iron ye-iron kunye nezicelo ezahlukeneyo.
Isinyithi esibalulekileyo silungele izicelo ezingafunekiyo ezifunwayo apho iindleko zenkcitho kunye neepropathi zoomatshini ziyanele.
Ngokwahlukileyo koko, intsimbi ye-ductile ikhethwe ngenxa yeemeko ezinzima ezinzima apho amandla aphezulu, ukunganyangeki kuyafuneka.
