Zotsatira za Zinthu Zosayera pa Ductility ya Tungsten Alloys

Ductility ya tungsten alloy imatanthawuza kusinthika kwa pulasitiki kwa zinthu za alloy isanaduke chifukwa cha kupsinjika.Ndiwophatikizika wamakina omwe ali ndi malingaliro ofanana a ductility ndi ductility, ndipo amakhudzidwa ndi zinthu zambiri, kuphatikiza kapangidwe kazinthu, chiŵerengero cha zinthu zopangira, kupanga, ndi njira zochiritsira.Zotsatirazi makamaka zimabweretsa chikoka cha zinthu zonyansa pa ductility wa tungsten aloyi.

Zinthu zonyansa zomwe zili mu kachulukidwe kachulukidwe ka tungsten zimaphatikiza kaboni, haidrojeni, okosijeni, nayitrogeni, phosphorous, ndi zinthu za sulfure.

Mpweya wa carbon: Nthawi zambiri, pamene mpweya wa carbon ukuwonjezeka, zomwe zili mu gawo la tungsten carbide mu alloy zimawonjezeka, zomwe zingapangitse kuuma ndi mphamvu ya tungsten alloy, koma ductility yake idzachepa.

Hydrogen element: Kutentha kwambiri, tungsten imakhudzidwa ndi hydrogen element kupanga hydrogenated tungsten, zomwe zimabweretsa kuchepa kwa ma ductility a ma alloys apamwamba kwambiri a tungsten, ndipo njirayi imasandukanso hydrogen embrittlement.

Mpweya wa okosijeni: Nthawi zambiri, kupezeka kwa chinthu cha okosijeni kumachepetsa kuphatikizika kwa ma tungsten alloys, makamaka chifukwa chinthu cha okosijeni chidzapanga ma oxide okhazikika okhala ndi tungsten, omwe angapangitse kupsinjika pamalire a tirigu ndi mbewu.

Nayitrojeni: Kuphatikizika kwa nayitrogeni kumatha kukulitsa mphamvu ndi kuuma kwa ma aloyi amphamvu yokoka amtundu wa tungsten, chifukwa kupanga njira yolimba pakati pa maatomu a nayitrogeni ndi tungsten kungayambitse kupotoza kwa lattice ndi kulimbikitsa.Komabe, ngati kuchuluka kwa nayitrogeni ndikwambiri, kupotoza kwa lattice ndi kusintha kwamankhwala kungayambitse kuphulika kwa aloyi, potero kumachepetsa ductility.

Phosphorus: Phosphorus imatha kulowa mu kachulukidwe kachulukidwe kakang'ono ka tungsten kudzera mu zonyansa za phosphide muzinthu zopangira kapena kuipitsa panthawi yopanga.Kukhalapo kwake kungayambitse kusokoneza malire a tirigu, potero kuchepetsa ductility wa alloy.

Sulfur element: Sulfur element imalimbikitsa kukula kwa tirigu, zomwe zimakhudzanso makina komanso ductility ya tungsten alloys.Kuphatikiza apo, sulfure imathanso kupanga brittle sulfides pamalire a tirigu ndi mbewu zolimba, kumachepetsanso kulimba komanso kulimba kwa aloyi.
