Iyo ductility ye tungsten alloy inoreva kugona kwepurasitiki deformation ye alloy zvinhu isati yaputika nekuda kwekushushikana. Musanganiswa wemichina yezvivakwa ine pfungwa dzakafanana dze ductility uye ductility, uye inokanganiswa nezvakawanda zvinhu, zvinosanganisira kuumbwa kwezvinhu, mbishi reshiyo yezvinhu, maitiro ekugadzira, uye mushure mekurapa nzira. Izvi zvinotevera zvinonyanya kuunza pesvedzero yezvinhu zvisina kuchena pane ductility ye tungsten alloys.
Zvinhu zvisina kuchena zviri muhuremu hwetungsten alloys zvinosanganisira kabhoni, haidrojeni, okisijeni, nitrogen, phosphorus, uye zvinhu zvesarufa.
Carbon element: Kazhinji kutaura, sezvo kabhoni yemukati inowedzera, zvirimo mu tungsten carbide chikamu mu alloy inowedzera, iyo inogona kuvandudza kuoma uye kusimba kwe tungsten alloy, asi ductility yayo inoderera.
Hydrogen element: Pakupisa kwakanyanya, tungsten inopindirana nehydrogen element kuti igadzire hydrogenated tungsten, izvo zvinotungamira kudzikira kweiyo ductility yehigh density tungsten alloys, uye maitiro aya zvakare anova hydrogen embrittlement.
Oxygen element: Kazhinji, kuvapo kweokisijeni element kunoderedza ductility ye high density tungsten alloys, kunyanya nokuti oxygen element ichaita yakagadzikana oxides ne tungsten, iyo ichaita kuti kushushikana mupfungwa pamiganhu yezviyo uye mukati mezviyo.
Nitrogen: Kuwedzerwa kwenitrogen kunogona kuvandudza kusimba uye kuoma kweiyo yakakwirira chaiyo giravhiti tungsten alloys, nekuti kuumbwa kwemhinduro yakasimba pakati penitrogen nemaatomu etungsten kunotungamira mukukanganiswa kwelattice nekusimbisa. Nekudaro, kana iyo nitrogen yemukati yakawandisa, kukanganiswa kwelattice uye kuita kwemakemikari kunogona kukonzera kuwedzera kwebrittleness yealloy, nokudaro kuderedza ductility yayo.
Phosphorus: Phosphorus inogona kupinda yakakwira density tungsten alloys kuburikidza nephosphide tsvina mune mbishi zvinhu kana kusvibiswa panguva yekugadzira. Kuvapo kwaro kunogona kutungamirira kune embrittlement yemiganhu yezviyo, nokudaro kuderedza ductility yealloy.
Sulfur element: Sulfur element inokurudzira kukura kwezviyo, izvo zvinozokanganisa ma mechanic properties uye ductility ye tungsten alloys. Uye zvakare, sarufa inogona zvakare kuumba brittle sulfides pamiganhu yezviyo uye coarse zviyo, zvichiwedzera kuderedza ductility uye kuoma kweiyo alloy.
