I-ductility ye-tungsten alloy ibhekisela ekhonweni lokuguquguquka kwepulasitiki le-alloy material ngaphambi kokuba liqhume ngenxa yengcindezi. Kuyinhlanganisela yezinto eziwumshini ezinemiqondo efanayo ye-ductility kanye ne-ductility, futhi kuthonywa izici eziningi, okuhlanganisa ukwakheka kwempahla, isilinganiso sempahla eluhlaza, inqubo yokukhiqiza, nezindlela zangemuva kokwelashwa. Okulandelayo kwethula ngokuyinhloko umthelela wezakhi zokungcola ku-ductility yama-tungsten alloys.
Izakhi zokungcola ezitholakala kuma-tungsten alloys ahlanganisa ikhabhoni, i-hydrogen, umoya-mpilo, i-nitrogen, i-phosphorus, nezakhi zesulfure.
Isici se-Carbon: Ngokuvamile, njengoba okuqukethwe kwekhabhoni kwanda, okuqukethwe kwesigaba se-tungsten carbide ku-alloy nakho kuyanda, okungathuthukisa ubulukhuni namandla we-tungsten alloy, kodwa i-ductility yayo izokwehla.
Isici se-hydrogen: Emazingeni okushisa aphezulu, i-tungsten ihlangana ne-hydrogen element ukuze yakhe i-hydrogenated tungsten, okuholela ekwehleni kwe-ductility yama-high density tungsten alloys, futhi le nqubo ibuye ibe yi-hydrogen embrittlement.
Isici se-oksijini: Ngokuvamile, ukuba khona kwe-oxygen element kuzonciphisa i-ductility ye-high density tungsten alloys, ikakhulukazi ngoba i-oxygen element izokwakha ama-oxides azinzile nge-tungsten, okuzokhiqiza ukugxila kokucindezeleka emingceleni yokusanhlamvu nangaphakathi kwezinhlamvu.
I-nitrogen: Ukwengezwa kwe-nitrogen kungathuthukisa amandla nobulukhuni bama-alloy we-tungsten adonsela phansi aphezulu, ngoba ukwakheka kwesisombululo esiqinile phakathi kwe-nitrogen nama-athomu e-tungsten kuzoholela ekuhlanekeni kwe-lattice nokuqinisa. Kodwa-ke, uma okuqukethwe kwe-nitrogen kuphezulu kakhulu, ukuhlanekezela kwe-lattice kanye nokusabela kwamakhemikhali kungase kuholele ekwandeni kokuqina kwe-alloy, ngaleyo ndlela kunciphise ukudumba kwayo.
I-Phosphorus: I-Phosphorus ingangena ku-high density tungsten alloys ngokusebenzisa ukungcola kwe-phosphide ezintweni ezingavuthiwe noma ukungcola phakathi nenqubo yokukhiqiza. Ukuba khona kwayo kungaholela e-embrittlement yemingcele yokusanhlamvu, ngaleyo ndlela kunciphise i-ductility ye-alloy.
Isici Sesulfure: Isici Sesulfure sikhuthaza ukukhula okusanhlamvu, okubuye kuthinte izakhiwo zemishini kanye ne-ductility yama-tungsten alloys. Ngaphezu kwalokho, isibabule singase senze ama-brittle sulfide emingceleni yokusanhlamvu kanye nezinhlamvu ezimahhadla, okuqhubekisele phambili ukunciphisa ukudumba nokuqina kwengxubevange.
