I-Ductility kwiMetals ichazwe
I-Ductility iyinxalenye yesakhono sensimbi yokumelana nokunyanzeliswa kwengxaki-naliphi na iqhosha elithatha iziphelo zombini eziphathekayo ngaphandle komnye. Umdlalo we-war-of-war unikeza umzekelo omhle wokuqina okuqinileyo okusetyenziswa kwintambo. I-Ductility yi-deformation yeplastiki eyenzeka ngenxa yezo ntlobo zengxaki. Igama elithi "ductile" ngokwezwi nezwi lithetha ukuba isicatshulwa sezinyithi siyakwazi ukutyulwa kumgca omncinci, kwaye asiyi kuba buthathaka okanye sibe yinto enzima.
Izitishi ezineziphumo eziphezulu okanye eziphantsi
Izitya zamanzi ezinobuninzi obuphezulu ezifana nobhedu zingathathwa kwiimbambo ezinde, ezincinci ngaphandle kokuphula. I-Copper iye yasebenza ngokugqithiseleyo njengomqhubi wombane ogqwesileyo, kodwa le ntsimbi ingaqhuba malunga nantoni na. Izitishi ezinamaqondo aphantsi, ezinjenge- bismuth , ziya kunqumla xa zifakwa phantsi kwengcinezelo.
Ukutshatyalaliswa kwamatyala ngokubhekiselele
Ngokwahlukileyo, ukungazinzi kuyinkqubo yenkxaso yesinyithi yokumelana nokunyanzeliswa, njengokwenyuka, ukugubungela okanye ukucindezela. Nangona ezi ngcamango zombini zinokubonakala zifana nomhlaba, izitye eziductile azithethi. Umzekelo oqhelekileyo wokohluko phakathi kwezi zimbini zakhiwo zikhokelela , ezinokuthi zingabonakali kakhulu kodwa zingekho i-ductile kakhulu ngenxa yesakhiwo sayo sekristal. Isakhiwo se-crystal sesinyithi sichaza indlela abaya kuyenza ngayo phantsi kwengcinezelo.
Iinqununu ze-athomu ezenza izinyithi ziyakunqumla phantsi koxinzelelo okanye ngokushenxisana okanye ukuhanjiswa.
Isakhiwo se-crystal sesinyithi ezininzi se-ductile sivumela i-athomu zensimbi ukuba zolulelwe kude, inkqubo ebizwa ngokuthi "i-twinning." Ezinye iinkonzo ze-ductile yilezo zilula ngokulula, kwaye ziphinde zenzeke nakwezinye izikhokelo.
Impembelelo yokushisa
I-Ductility kwizinyithi nayo ihambelana nokushisa.
Njengoko isinyithi sivutha, ngokuqhelekileyo ziba ziincinci, zivumela ukulungiswa kweplastiki. Ngamanye amagama, ininzi yinyithi ibe yiductile ngakumbi xa ishushu kwaye iyakwazi ukugqithiselwa kalula kwiifayili ngaphandle kokuphula. Inkokeli ibonisa ukuba yinto ehlukile kulo mgaqo, njengoko iya kuba yinto ebenzileyo njengokuba ishushu.
Ziziphi iiMetroli zeDuctile?
Nangona kunzima ukuthelekisa ngokuchanekileyo ubuqhetseba phakathi kwesimbi, igolide kunye neplatinum zibhekwa njengowona ductile. Kuthiwa igolide ingathathwa kwiinkambo ukuze i-ounce enye yensimbi ifikelele kwiiyure ezingama-50.
