Gukoresha ibyuma byangiritse

Ibyuma bivunagura ni ubwoko bwibyuma bifite ubushyuhe buhebuje kandi bushonga cyane.

Ibi bintu byo kwangara, kimwe nibintu bitandukanye hamwe nuruvange rugizwe na byo, bifite byinshi biranga.Usibye gushonga cyane, bifite kandi imbaraga zo kurwanya ruswa, ubwinshi bwinshi, kandi bikomeza imbaraga zubukanishi mubushyuhe bwinshi.Ibi biranga bivuze ko ibyuma bivunika bishobora gukoreshwa mubice byinshi, nka electrode yo gushonga ibirahuri, ibice by'itanura, intego za sputter, radiator na crucibles.Impuguke zo mu ishami ry’ikoranabuhanga rya RSM zerekanye ibyuma bibiri bikoreshwa cyane mu kuvunika no kubikoresha, aribyo molybdenum na niobium.

molybdenum

Nicyuma gikoreshwa cyane kandi cyanone kandi gifite imiterere yubukanishi munsi yubushyuhe bwo hejuru, kwaguka kwinshi kwubushyuhe hamwe nubushyuhe bwinshi.

Iyi miterere isobanura ko molybdenum ishobora gukoreshwa mugukora ibice biramba mugukoresha ubushyuhe bwinshi, nko gutwara ibice, feri ya feri ya lift, ibice by'itanura, no guhimba bipfa.Molybdenum ikoreshwa mumirasire kubera ubushyuhe bwayo bwinshi (138 W / (m · K)).

Usibye imiterere yubukanishi nubushyuhe, molybdenum (2 × 107S / m), ikora molybdenum ikoreshwa mugukora amashanyarazi ya elegitoronike.

Molybdenum isanzwe ivangwa nibyuma bitandukanye kubisabwa bisaba imbaraga zumuriro, kuko molybdenum iracyafite imbaraga nyinshi no mubushyuhe bwinshi.TZM ni umusemburo uzwi cyane wa molybdenum, urimo 0.08% zirconium na titanium 0.5%.Imbaraga zuruvange kuri 1100 ° C zikubye kabiri inshuro ebyiri za molybdenum idashimishije, hamwe no kwaguka kwinshi kwubushyuhe hamwe nubushyuhe bwinshi.

niobium

Niobium, icyuma cyangiritse, gifite ihindagurika ryinshi.Niobium ifite ubushobozi bwo gukora cyane no mubushyuhe buke, kandi ifite uburyo bwinshi, nka file, isahani hamwe nimpapuro.

Nkicyuma cyangiritse, niobium ifite ubucucike buke, bivuze ko ibinyobwa bya niobium bishobora gukoreshwa mugukora ibikoresho byo mu rwego rwo hejuru byoroheje bifite uburemere bworoshye.Kubwibyo, niobium alloys nka C-103 isanzwe ikoreshwa muri moteri ya roketi yo mu kirere.

C.

Byongeye kandi, ugereranije nibyuma bitandukanye byangiritse, bifite igice cyo hasi cya neutron cross cross, kigaragaza ubushobozi mubisekuruza bizaza bikoreshwa mubisasu bya kirimbuzi.
