Munguva pfupi yapfuura, vatengi vazhinji vakabvunza nezve yakakwirira entropy alloy.Ndeipi nzira yekugadzira yepamusoro entropy alloy?Zvino ngatigovane newe nemupepeti weRSM.
Nzira dzekugadzira dzepamusoro entropy alloys dzinogona kukamurwa kuita nzira nhatu huru: kusanganiswa kwemvura, kusanganisa kwakasimba uye kusanganisa gasi.Kusanganiswa kweLiquid kunosanganisira arc kunyunguduka, kuramba kunyungudika, induction kunyungudika, Bridgman solidification uye laser additive kugadzira.Muchidzidzo chacho, alloys akawanda akakwira entropy anogadzirwa nekunyunguduka kwearc, uye kunyungudika kwearc kunoitika munzvimbo yevacuum yakavharwa argon yekukanda maalloys akanyungudutswa.Iyo alloy ichagadzirwa inonyungudutswa uchishandisa vacuum arc melter.Muchina wekunyungudutsa glue wakashongedzerwa nebhatani crucible.Kunyunguduka kunoitwa pachishandiswa tungsten electrode inoshandiswa iyo inoshandisa simbi zvidimbu semachaji kurova arc.Chamber inozopombwa pachishandiswa turbomolecular pump uye roughing pump kuti iwane inenge 3 × 10 − 4 Tor.Argon inozadzwa mukamuri yekudzikisa zvishoma kudzvanywa kuitira kuti igadzire plasma kana arc ichirova.Ipapo dziva rakanyungudutswa rinomutswa neplasma yakajairika.Iyo nzira inodzokororwa kakawanda kuti iwane kufanana kwekuumbwa.
Chero zvazvingava, dambudziko rekupisa zvikamu pamwe chete rinowanzoita hypoeutectic.Nekuda kwekunonoka kutonhora kunonoka, chimiro uye saizi ye block ingots ishoma, uye zvinodhura kushandisa tekinoroji iyi kugadzira yakakwira entropy alloys.Iyo yakasimba yekusanganisa nzira inosanganisira mechanical alloying uye inotevera yekusimbisa maitiro.Zvimwe zvidzidzo zvinoratidza kuti mechanical alloying inogadzira yunifomu uye yakagadzikana nanocrystalline microstructure.Iyo gasi yekusanganisa nzira inosanganisira molecular beam epitaxy, sputtering deposition, pulsed laser deposition (PLD), vapor deposition uye atomic layer deposition.
