Haufinyane tjena, bareki ba bangata ba botsitse ka alloy e phahameng ea entropy.Mokhoa oa ho etsa alloy e phahameng ea entropy ke ofe?Joale a re e arolelaneng le uena ka mohlophisi oa RSM.
Mekhoa ea tlhahiso ea li-alloys tse phahameng tsa entropy li ka aroloa ka litsela tse tharo tse kholo: ho kopanya metsi, ho kopanya ho tiileng le ho kopanya khase.Ho kopanya ha metsi ho kenyelletsa ho qhibiliha ha arc, ho qhibiliha ha khanyetso, ho qhibiliha ha induction, Bridgman solidification le tlhahiso ea laser additive.Thutong, li-alloys tse ngata tse phahameng tsa entropy li entsoe ka ho qhibiliha ha arc, 'me ho qhibiliha ha arc ho etsahala tikolohong ea vacuum e tiisitsoeng ea argon ea ho lahla li-alloys tse qhibilihisitsoeng.The alloy e lokelang ho etsoa e qhibilihisoa ho sebelisoa vacuum arc melter.Mochini o qhibilihang oa sekhomaretsi o na le konopo ea crucible.Ho qhibiliha ho finyelloa ka ho sebelisa electrode ea tungsten e sebelisoang e sebelisang likaroloana tsa tšepe e le litefello ho otla arc.Ka mor'a moo, kamore eo e pompeloa ho sebelisoa pompo ea turbomolecular le pompo e mahoashe ho fumana hoo e ka bang 3 × 10 − 4 Tor.Argon e tlatsitsoe ka kamoreng ho fokotsa khatello hanyenyane e le ho etsa plasma ha arc e otla.Joale letamo le qhibilihisitsoeng le tsosoa ke plasma e tloaelehileng.Joale ts'ebetso e phetoa ka makhetlo a 'maloa ho finyella ho tšoana ha motsoako.
Ho sa tsotellehe boemo leha e le bofe, phephetso ea ho futhumatsa likarolo hammoho e atisa ho theha hypoeutectic.Ka lebaka la lebelo le liehang la ho pholile, sebōpeho le boholo ba li-ingots tsa li-block li fokotsehile, 'me ho batla ho theko e boima ho sebelisa theknoloji ena ho etsa li-alloys tse phahameng tsa entropy.Tsela e tiileng ea ho kopanya e kenyelletsa motsoako oa mechine le mekhoa e latelang ea ho kopanya.Liphuputso tse ling li bonts'a hore motsoako oa mochini o hlahisa nanocrystalline microstructure e ts'oanang le e tsitsitseng.Tsela ea ho kopanya khase e kenyelletsa molecular beam epitaxy, sputtering deposition, pulsed laser deposition (PLD), vapor deposition le atomic layer deposition.
