Kutshanje, abathengi abaninzi baye babuza malunga ne-entropy alloy ephezulu. Yeyiphi indlela yokwenziwa kwe-entropy alloy ephezulu? Ngoku masabelane nawe ngomhleli weRSM.
Iindlela zokwenziwa kwee-alloys eziphezulu ze-entropy zinokuhlulwa zibe ziindlela ezintathu eziphambili: ukuxuba ulwelo, ukuxuba okuqinileyo kunye nokuxuba igesi. Ukuxutywa kolwelo kubandakanya ukunyibilika kwe-arc, ukunyibilika kokumelana, ukunyibilika kwe-induction, ukuqina kweBridgman kunye nokuveliswa kwe-laser additive. Kuphononongo, uninzi lweealloyi eziphezulu ze-entropy zenziwa ngokunyibilika kwe-arc, kwaye ukunyibilika kwe-arc kwenzeka kwindawo ye-argon etywiniweyo yokuphosa ialloys ezinyibilikisiweyo. I-alloy eza kuveliswa iyanyibilikiswa kusetyenziswa i-vacuum arc melter. Umatshini wokunyibilika kweglue uxhotyiswe ngeqhosha leqhosha. Ukunyibilika kufezwa ngokusebenzisa i-electrode ye-tungsten esetyenziswayo esebenzisa iincinci zetsimbi njengeentlawulo zokubetha i-arc. Igumbi ke limpontshwa kusetyenziswa impompo ye-turbomolecular kunye nempompo erhabaxa ukufumana malunga ne-3 × 10 − 4 Tor. I-Argon izaliswe kwigumbi ukunciphisa kancinane uxinzelelo ukwenzela ukuba yenze i-plasma xa i-arc ibetha. Emva koko i-pool etyhidiweyo ishukunyiswa yi-plasma eqhelekileyo. Inkqubo iphinda iphindwe ngamaxesha amaninzi ukufezekisa ukufana kokubunjwa.
Kwimeko nayiphi na into, umngeni wokufudumeza amacandelo adibeneyo avame ukwenza i-hypoeutectic. Ngenxa yesantya esicothayo sokupholisa, imilo kunye nobukhulu bee-ingots zebhloko zilinganiselwe, kwaye kuyabiza kakhulu ukusebenzisa le teknoloji ukwenza ii-alloys eziphezulu ze-entropy. Indlela yokuxuba eqinileyo ibandakanya i-alloying yomatshini kunye neenkqubo zokuhlanganiswa okulandelayo. Olunye uphando lubonisa ukuba i-alloying yomatshini ivelisa i-microstructure efanayo kunye ne-nanocrystalline microstructure. Indlela yokuxuba igesi ibandakanya i-epitaxy ye-molecular beam, i-sputtering deposition, i-pulsed laser deposition (PLD), i-vapor deposition kunye ne-atomic layer deposition.
