Lapho insimbi icwebezela, iyi-polycrystal eyakhiwe izinhlamvu eziningi.Ubukhulu bokusanhlamvu bungabonakaliswa ngenani lezinhlamvu kuvolumu yeyunithi.Uma isibalo siphezulu, sincane usayizi wokusanhlamvu.Inombolo yezinhlamvu ngeyunithi ngayinye yesiphambano sengxenye noma ububanzi obumaphakathi bezinhlamvu ngokuvamile busetshenziselwa izinjongo zokulinganisa.Ubukhulu bokusanhlamvu bensimbi bunomthelela obalulekile ezindaweni eziningi zensimbi.Umthelela wesayizi wezinhlamvu ze-tungsten carbide empeleni uwumphumela wobukhulu bendawo yomngcele wokusanhlamvu.Okungcono usayizi wokusanhlamvui-tungsten carbide, indawo yomngcele wokusanhlamvu inkulu futhi iba nomthelela omkhulu ezimpahleni.Ezimweni zomshini wezinga lokushisa legumbi lezinsimbi, ngokuvamile lapho okusanhlamvu kucolekile, kuyanda amandla nobulukhuni, kuyilapho ipulasitiki nokuqina nakho kuba ngcono.Lokhu kungenxa yokuthi, lapho okusanhlamvu kucolisekile, kulapho ukwakheka kwepulasitiki okuthe xaxa kungahlakazwa khona ngezinhlamvu eziningi, ukuze ipulasitiki iyunifomu eyengeziwe.
i-deformation, i-concentration encane yokucindezeleka kwangaphakathi;futhi lapho okusanhlamvu kucwebe, kuba nekristalu eyengeziwe, imingcele yokusanhlamvu egobile kakhulu;amathuba engeziwe okuhlangana okusanhlamvu nokusanhlamvu, okubi kakhulu ekusakazeni nasekuthuthukisweni kwemifantu, ukuqina komunye nomunye, amandla angcono kanye nokuqina.Ithebula libala umthelela wosayizi wokusanhlamvu kuzakhiwo zemishini zensimbi emsulwa.Kusukela etafuleni kungabonakala ukucwenga okusanhlamvu ukuthuthukisa izakhiwo mechanical zensimbi ekamelweni lokushisa kudlala indima enkulu, ngakho-ke, ngokuvamile njalo ithemba ukuthiimikhiqizo ye-tungsten carbideImpahla ingcono kakhulu okusanhlamvu.
Kodwa emsebenzini wokushisa ophezulu wezinto zensimbi, okusanhlamvu kukhulu kakhulu noma kuncane kakhulu akukuhle.Ngakho-ke, ngokuvamile bafuna ukuthola usayizi wokusanhlamvu omaphakathi, kodwa kwezinye izimo bathemba ukuthi okusanhlamvu kukhulu futhi kukhudlwana kungcono.Isibonelo, ukwakhiwa kwamamotho kagesi nama-transformer kuyishidi lensimbi ye-silicon, okusanhlamvu okuqinile, ukulahleka kwetheyiphu kuncane, kuya phezulu ukusebenza kahle.Ngamafuphi, umthelela wosayizi wokusanhlamvu ekusebenzeni kwensimbi unezici eziningi, ekuhlaziyeni okuqondile kwesimo esithile
