Ukuqaliswa komenzi womandlalo wefenitshala yeglasi yentsimbi1

Isishwankathelo sefenitshala yeglasi yentsimbi yaziswa. Ifenitshala yeglasi yentsimbi luhlobo olubalulekileyo lwefenitshala yanamhlanje, njengoko negama lisitsho, ifenitshala yeglasi yentsimbi yindibaniselwano yefenitshala yentsimbi kunye neglasi, ifenitshala yeglasi yentsimbi kunye neempawu zayo ezimfutshane neziluncedo zithandwa ngabantu abaninzi ngakumbi. Kulandelwe 'isixeko sefenitshala ye-xianghe' ye-intanethi ye-intanethi phantsi kwe-mall encinci kunye ukuze ufunde malunga nokwaziswa kwefenitshala yeglasi yentsimbi! Ukuqaliswa kwefenitshala yeglasi yentsimbi. Ifenitshala yeglasi yentsimbi luhlobo olubalulekileyo lwefenitshala yanamhlanje, njengoko negama lisitsho, ifenitshala yeglasi yentsimbi yindibaniselwano yefenitshala yentsimbi kunye neglasi, ifenitshala yeglasi yentsimbi kunye neempawu zayo ezimfutshane neziluncedo zithandwa ngabantu abaninzi ngakumbi. Kulandelwe 'isixeko sefenitshala ye-xianghe' ye-intanethi ye-intanethi phantsi kwe-mall encinci kunye ukuze ufunde malunga nokwaziswa kwefenitshala yeglasi yentsimbi! Iglasi ye-Metallic ikwabizwa ngokuba yi-amorphous alloy, kwisicelo semathiriyeli yefenitshala, ineenzuzo zetsimbi kunye neglasi, kwaye yoyise izinto ezingalunganga. Njengeglasi iethe-ethe, akukho malleability. Amandla aphezulu ngaphezu kwentsimbi, ubulukhuni beglasi yesinyithi ngaphezu kwentsimbi yesixhobo esinzima, kwaye inobunzima obuthile kunye nokuqina, ngoko ke, abantu bancoma iglasi yentsimbi ngokuthi 'ungankqonkqozi ayaphulwa,' ukumkani 'weglasi'. Xa abantu abaninzi becinga ngeglasi, iglasi ikhawuleza itsibe ingcamango yeengqondo zethu. Kodwa phantsi kweemeko ezithile, iglasi yensimbi ingayenza, umzekelo: olu hlobo lweglasi lunokusetyenziswa njengento efanelekileyo yokuguqula amandla kunye neeklabhu zegalufa. Johns Hopkins (izibuko laseBaltimore, 约翰霍普金斯大学) Umphandi kwiyunivesithi yaseTodd C. I-Hufnagel isebenza kwimveliso yeempawu eziphezulu, ezilastiki kunye nemagnethi yendlela yeglasi yentsimbi. I-Hufnagel ifuna ukwazi, xa ukubunjwa kweglasi yesinyithi, kwenzeka xa kunyibilika ukupholisa kwesinyithi kuguquko oluluqilima lwe-metallographic. Kwizazinzulu, iglasi inokuba kuko nakuphi na ukupholisa ukusuka kulwelo ukuya kokuqinileyo kwaye akukho mathiriyeli yekristale. Uninzi lwentsimbi yokupholisa icrystallization, imithetho yee-athomu ezicwangciswe ngendlela ebizwa ngokuba yicrystal lattice. Ukuba akwenzeki icrystallization kunye nolungiselelo lweathom aluqhelekanga, lusenza iglasi yentsimbi. Musa ukuyithanda iglasi, isinyithi, iglasi ayibonakali okanye ingabonakali, isakhiwo sabo se-athomu sinqabile ukwenzela ukuba babe neepropati ezikhethekileyo zoomatshini kunye neempawu zemagneti. Iintsimbi eziqhelekileyo ngenxa yeziphene zazo ze-lattice kunye nokulula ukugoba ukuguqulwa okanye ukukhokelela ekulahlekelweni okusisigxina kwefomu. Ngokwahlukileyo koko, iglasi yentsimbi emva koguquko kunokwenzeka ukuba ibuyele kubume bayo bokuqala. Ukunqongophala kwesiphene sekristale kwenza iglasi yentsimbi etyhidiweyo yentsimbi esebenzayo isebenze izinto ezinozibuthe. Ubukho iglasi metallic inokulandelwa emva kwenkulungwane s, Kramer kuqala ingxelo ukubekwa kwerhasi yeglasi yentsimbi, metallurgists kwiminyaka, wafunda ngokuxutywa isixa esithile metal - - Ukubonisa iikristale, ezifana nickel kunye zirconium, Klement kwiziko California lobuchwepheshe, kunye Duwez AuSi iglasi metallic ilungiswa ngokucima iteknoloji. Xa umaleko obhityileyo we-alloyi phantsi kwekhulu leqondo lokupholisa ngesantya sesibini, benza iglasi yesinyithi. Kodwa ngenxa yokuba ifuna ukupholisa ngokukhawuleza, zinokwenziwa kuphela zibe yimisonto ebhityileyo, ucingo okanye umgubo. Kutshanje, izazinzulu ngokuxuba iziqalelo athom, ezine okanye ezintlanu ubukhulu ezahlukeneyo ukwenza ezifana ezahlukeneyo metal strip yeglasi. Guqula ubungakanani beathom yenze ixutywe ukwenza iglasi ukuze ibenzima ngakumbi. Kwishishini yenye yeenjongo zale ngxubevange intsha isetyenziselwa ukwenza intloko yegalufa
