Incazelo kanye nezinhlobo zeMechanical Metallurgy
I-metallurgy yemishini iyigatsha lesayensi nobuchwepheshe eligxile ekuqondeni ukuziphatha kwemishini kanye nezakhiwo zomzimba zezinsimbi kanye nama-alloy azo, kanye nendlela yokushintsha nokwenza ngcono lezi zakhiwo ukuze zivumelane nezidingo zezimboni kanye nezicelo. Kuyinkambu yezifundo ezahlukahlukene ehlanganisa izimiso ezivela ku-physics, i-chemistry, kanye nobunjiniyela ukuklama, ukukhiqiza, kanye nokuhlola izinto zensimbi zezinhlelo zokusebenza ezahlukahlukene. Kulesi sihloko, sizohlola incazelo kanye nezinhlobo ezahlukene ze-metallurgy yemishini.
Ukuqonda i-Mechanical Metallurgy
Empeleni, i-mechanical metallurgy yisayensi efunda izinqubo zokukhiqiza izinsimbi, ama-alloy ensimbi, kanye nemikhiqizo eyenziwe ngazo, kanye nendlela lezi zinsimbi eziziphatha ngayo ngaphansi kwezimo ezahlukahlukene zomzimba. Le sayensi ayihlanganisi nje kuphela isakhiwo esincane sezinsimbi nama-alloy, kodwa futhi nokuguqulwa kwesigaba, ukwakheka kokuqhekeka, amandla, ukuguquguquka, kanye nokumelana nezinhlobo ezahlukene zokwehluleka njengokugqwala nokukhathala.
Enye yezinhloso eziyinhloko ze-mechanical metallurgy ukuguqula isakhiwo esincane sezinsimbi ukuze kufezwe izakhiwo ezifiselekayo zemishini. Lokhu kungabandakanya izinqubo ezahlukahlukene njengokushisa, ukucima, ukufudumala, noma ukusebenza ngokubanda. Inqubo ngayinye inomthelela othize esakhiweni esincane, ngakho-ke, izakhiwo zemishini zensimbi.
Izinhlobo zeMechanical Metallurgy
I-metallurgy yemishini ingahlukaniswa ngezinhlobo eziningana noma amasimu amancane ngokusekelwe ezinqubweni namasu asetshenzisiwe. Amanye amasimu amancane ayinhloko afaka:
1. I-Metallurgy Yomzimba
2. I-Process Metallurgy
3. I-Metallurgy Yokumba Izinto Ezimbiwayo
4. I-Powder Metallurgy
5. I-Welding Metallurgy
Ake sixoxe ngensimu ngayinye encane ngemininingwane eminingi.
1. I-Metallurgy Yomzimba
I-Physical metallurgy iyigatsha lobunjiniyela elifunda isakhiwo kanye nezakhiwo zomzimba zezinsimbi kanye nama-alloy azo. Lokhu kufaka phakathi ukuhlaziywa kwesakhiwo esincane, ukusatshalaliswa kwesigaba, ukuguqulwa kwesigaba, kanye nokusebenzisana phakathi kwezakhiwo ezincane kanye nezakhiwo zemishini njengamandla, ukuguquguquka, kanye nobunzima.
Ukuguqulwa Kwesigaba: Ucwaningo lokuthi isakhiwo sezinsimbi sishintsha kanjani ngaphansi kwezimo ezahlukene zokushisa nokucindezela.
Izindlela Zokuhlola Okungabhubhisi (NDT): Amasu okuhlola izakhiwo zensimbi ezisebenza ngomshini nezingokwenyama ngaphandle kokuzibhubhisa.
I-Fracture Mechanics: Ukuhlaziywa kokuthi imifantu ikhula kanjani ezintweni zensimbi nokuthi ingavinjelwa kanjani.
2. I-Process Metallurgy
I-process metallurgy igxile emasu okukhiqiza nokubumba izinsimbi nama-alloy. Lokhu kuhlanganisa izindlela ezahlukene zokubumba, ukuhlanganisa, ukugoqa, ukukhipha, kanye nokudweba.
Ukubumba: Inqubo yokuncibilikisa insimbi bese uyithela esikhumbeni ukuze kwakheke umkhiqizo owufunayo.
Ukwakha: Inqubo yokubumba insimbi ngokusebenzisa umfutho ophezulu. Ngokuvamile isetshenziselwa ukudala izingxenye ezidinga amandla aphezulu kanye nokuguquguquka.
Ukugoqa Nokukhipha: Le ndlela isetshenziselwa ukudala amashidi ensimbi namaphrofayili ngokugeleza insimbi ngama-roller noma ama-dies.
3. I-Metallurgy Yokumba Izinto Ezimbiwayo
I-Extractive metallurgy iyigatsha le-metallurgy eligxile enkambisweni yokukhipha izinsimbi ema-ore azo. Le nqubo ihilela amasu ahlukahlukene amakhemikhali kanye nawomzimba okuhlukanisa nokuhlanza izinsimbi kumaminerali angaphekiwe.
Inqubo ye-pyrometallurgical: Ukushisa i-ore emazingeni okushisa aphezulu ukuze uyiguqule ibe yinsimbi emsulwa.
Inqubo ye-Hydrometallurgical: Ukusetshenziswa kwezixazululo zamanzi ukukhipha izinsimbi ema-ore ngokuwakhipha nokuwancibilikisa.
Inqubo ye-Electrometallurgical: Ukusetshenziswa kukagesi ukuhlanza izinsimbi ngenqubo ye-electrolysis.
4. I-Powder Metallurgy
I-powder metallurgy igatsha elihilela ukusetshenziswa kwempuphu yensimbi ukwenza imikhiqizo yensimbi ngenqubo yokusila. Lokhu kuhilela ukuxuba i-metal powders, ukuhlanganisa i-powders ngesikhunta, kanye nokushisa kuze kufike ezingeni lokushisa eliphezulu ngokwanele ukuze kubangele ukuthi izinhlayiya zempuphu zihlangane.
Ukuhlanza: Inqubo yokushisa impuphu yensimbi ngaphansi kwendawo yayo yokuncibilika ukuze kubangele ukuthi izinhlayiya zihlangane ndawonye ngaphandle kokuncibilika ngokuphelele.
Ukucindezela Okungashintshi Okubandayo (i-CIP): Indlela yokuhlanganisa impuphu yensimbi ngaphansi kwengcindezi engashintshi ekushiseni kwegumbi.
Ukucindezela Okushisayo Okungashintshi (i-HIP): Indlela yokuhlanganisa izimpushana zensimbi ngaphansi kwengcindezi engashintshi emazingeni okushisa aphezulu, evame ukusetshenziselwa ukuqeda ukubhoboka nokuthuthukisa izakhiwo zemishini.
5. I-Welding Metallurgy
Ukushisela kuyindlela yokuhlanganisa izingcezu ezimbili noma ngaphezulu zensimbi ngokuncibilikisa izinto eziyisisekelo bese ufaka izinto zokugcwalisa. Le nqubo ivame ukuhilela ukusetshenziswa kokushisa, ingcindezi, noma inhlanganisela yakho kokubili.
Ukushisela i-Arc: Inqubo yokushisela esebenzisa ugesi ukudala i-arc kagesi phakathi kwe-electrode nezinto eziyisisekelo, bese incibilikisa insimbi bese yakha ijoyinti.
Ukushisela Ukumelana: Indlela yokushisela esebenzisa ukumelana kukagesi ukukhiqiza ukushisa endaweni okufanele ihlanganiswe.
Ukushisela Okunezingxabano: Indlela yokushisela ehilela ukungqubuzana phakathi kwezindawo ezimbili zensimbi ezicindezelwe ndawonye kuze kube yilapho kwenzeka ukushisela.
Isicelo Embonini
I-metallurgy yemishini inezinhlelo zokusebenza ezibanzi emikhakheni eyahlukene yezimboni, okuhlanganisa izimoto, izindiza, izinto zikagesi, ezokwakha kanye nezamandla. Ngokuqonda nokusebenzisa izimiso ze-metallurgy yemishini, onjiniyela bangaklama izinto zensimbi eziqinile, ezilula, nezihlala isikhathi eside.
Imboni Yezimoto: Ukusetshenziswa kwezinto zensimbi ezinamandla aphezulu ezingaphansi kwe-alloy (HSLA) zezingxenye zezimoto eziqinile nezilula.
Imboni Yezindiza: Ukuthuthukiswa kwe-titanium kanye ne-aluminium alloys ezinezinhlaka ezilula kodwa eziqinile zezindiza.
Imboni Yezinto Eziphathekayo: Ukusetshenziswa kwezinto zensimbi ezinokushisa okuphezulu kanye nokushisa kukagesi ezingxenyeni ze-elekthronikhi.
Isiphetho
I-metallurgy yemishini iyinsimu eyinkimbinkimbi nobuhle, ehlanganisa izimiso ezivela kwezesayensi ezahlukene eziyisisekelo ukuxazulula izinkinga ezingokoqobo empilweni yansuku zonke. Ngokuqonda izinhlobo ezahlukene namasu e-metallurgy yemishini, onjiniyela nososayensi bangaklama, bakhiqize, futhi balungise izinsimbi nama-alloy ukuze kusetshenziswe izinto eziningi, kusukela emishinini esindayo kuya kumadivayisi amancane kagesi. Ngakho-ke, intuthuko kanye nokutholakele kulo mkhakha akugcini nje ngokuthinta imboni kodwa futhi kunegalelo elikhulu entuthukweni yezobuchwepheshe kanye nekhwalithi yokuphila komuntu.
