Na nso nso a, ọtụtụ ndị ahịa jụrụ ajụjụ banyere elu entropy alloy.Gịnị bụ mmepụta usoro nke elu entropy alloy?Ugbu a, ka anyị kesara gị ya site n'aka onye nchịkọta akụkọ RSM.
Enwere ike kewaa ụzọ nrụpụta nke elu entropy alloys ụzọ atọ: ngwakọta mmiri mmiri, ngwakọta siri ike na ngwakọta gas.Ngwakọta mmiri na-agụnye agbaze arc, mgbaze nguzogide, mgbaze induction, Bridgman solidification na mmepụta laser.N'ime ọmụmụ ihe ahụ, a na-eme ọtụtụ ihe mkpuchi entropy dị elu site na mgbaze arc, na mgbaze arc na-apụta na oghere argon gburugburu oghere nke na-agbaze alloys gbazere.A na-agbaze alloy a ga-emepụta site na iji mgbaze oghere oghere.Igwe na-agbaze gluu nwere bọtịnụ crucible.A na-arụzu mgbaze site na iji tungsten electrode a na-eri eri nke na-eji irighiri ihe igwe dị ka ebubo ịkụ arc.A na-agbanyezi ụlọ ahụ site na iji mgbapụta turbomolecular na igwe na-agbagharị agbagharị iji nweta ihe dịka 3 × 10 - 4 Tor.A na-ejupụta Argon n'ime ụlọ ahụ iji belata ntakịrị nrụgide ka o wee mepụta plasma mgbe arc na-akụ.Mgbe ahụ, a na-akpali ọdọ mmiri a wụrụ awụ site na plasma nkịtị.A na-emeghachi usoro ahụ ugboro ugboro ugboro ugboro iji nweta otu nke mejupụtara.
N'ọnọdụ ọ bụla, ihe ịma aka nke ikpokọta ihe ndị ahụ na-eme ka ọ bụrụ hypoeutectic.N'ihi ngwa ngwa jụrụ oyi, ọdịdị na nha nke block ingots dị oke, ọ dịkwa oke ọnụ iji teknụzụ a rụpụta alloys entropy dị elu.Ụzọ ngwakọta siri ike na-agụnye nhazi ígwè ọrụ yana usoro nhazi na-esote.Ụfọdụ nnyocha na-egosi na n'ibu alloying na-arụpụta otu na kwụsiri ike nanocrystalline microstructure.Ụzọ ngwakọta gas na-agụnye epitaxy molecular beam epitaxy, nkwụnye sputtering, pulsed laser deposition (PLD), vepor deposition and atomic Layer deposition.
