Powder metallurgy tungsten mubusanzwe ifite ingano nziza, ubusa bwayo bwatoranijwe nubushyuhe bwo hejuru bwo guhimba no kuzunguruka, ubusanzwe ubushyuhe bugenzurwa hagati ya 1500 ~ 1600 ℃.Nyuma yubusa, tungsten irashobora kuzunguruka, guhimbwa cyangwa kuzunguruka.Gutunganya igitutu mubisanzwe bikorwa munsi yubushyuhe bwa rerystallisation, kubera ko imbibi zingano za tungsten zongeye gushyirwaho zoroshye, ibyo bikaba bigabanya imikorere.Kubwibyo, hamwe no kwiyongera kwamafaranga yatunganijwe yose ya tungsten, ubushyuhe bwo guhindura ibintu buragabanuka.
Isahani ya Tungsten irashobora kugabanwa mubice bishyushye, kuzunguruka no gukonja.Bitewe no kurwanya ihindagurika ryinshi rya tungsten, ibizunguruka bisanzwe ntibishobora kuzuza neza ibyangombwa bisabwa bya plaque tungsten, mugihe hagomba gukoreshwa ibizingo bikozwe mubikoresho bidasanzwe.Muburyo bwo kuzunguruka, ibizunguruka bigomba gushyuha, kandi ubushyuhe bwo gushyuha ni 100 ~ 350 ℃ ukurikije ibihe bitandukanye.Ibibabi birashobora gutunganywa gusa mugihe ubucucike bugereranije (ikigereranyo cyubucucike nyabwo nubucucike bwa theoretical) kiri hejuru ya 90%, kandi gifite uburyo bwiza bwo gukora neza kuri 92 ~ 94%.Ubushyuhe bwa tungsten ni 1,350 ~ 1.500 ℃ mugihe gishyushye;niba ibipimo byo guhindura ibintu byatoranijwe nabi, ibibanza bizashyirwa kumurongo.Ubushyuhe bwo gutangira ubushyuhe buzunguruka ni 1,200 ℃;Isahani ya 8mm yubushyuhe irashobora kugera ku bunini bwa 0.5mm binyuze mu kuzunguruka.Isahani ya Tungsten iri hejuru cyane yo kurwanya deformasiyo, kandi umubiri wikiziga urashobora kugororwa no guhindurwa mugikorwa cyo kuzunguruka, bityo amasahani azakora umubyimba udahuje icyerekezo cyerekeranye n'ubugari, kandi urashobora gucika kubera ihinduka ridahuje rya bose. ibice muburyo bwo guhanahana cyangwa guhinduranya urusyo.Ubushyuhe bwimyanya yubushyuhe bwa 0.5mm yuburebure ni ubushyuhe bwicyumba cyangwa hejuru yubushyuhe bwicyumba;hamwe n'ubukonje, impapuro zigomba kuzunguruka mu mpapuro 0.2mm z'ubushyuhe ku bushyuhe bwa 200 ~ 500 ℃.Mugihe cyanyuma cyo kuzunguruka, amabati ya tungsten yoroheje kandi maremare.Kugirango ushushe neza amasahani, grafite cyangwa molybdenum disulphide ikunze gutwikirwa, ibyo ntibifite akamaro gusa mu gushyushya amasahani ahubwo binagira ingaruka zo gusiga muburyo bwo gutunganya.
