Kwanan nan, abokan ciniki da yawa sun yi tambaya game da high entropy gami.Mene ne hanyar masana'anta na high entropy gami?Yanzu bari mu raba tare da ku ta editan RSM.
Hanyoyin masana'antu na manyan allunan entropy za a iya raba su zuwa manyan hanyoyi guda uku: hadawar ruwa, hadawa mai ƙarfi da haɗakar gas.Haɗin ruwa ya haɗa da narkewar baka, narkewar juriya, narkewar induction, ƙarfafa Bridgman da masana'anta na Laser.A cikin binciken, mafi yawan manyan allunan entropy ana yin su ne ta hanyar narkewar baka, kuma narkewar baka yana faruwa a cikin mahalli mai ruɗi na argon na jefar da narkakkar gami.Garin da za a kera ana shayar da shi ta amfani da narkewar baka.Na'urar narkewar manne tana sanye da maɓalli crucible.Ana samun narkewa ta amfani da na'urar tungsten da ake amfani da ita wacce ke amfani da barbashi na ƙarfe azaman caji don bugi baka.Sannan ana yin famfo ɗakin ta hanyar amfani da famfo mai turbomolecular da famfon mai jujjuyawa don samun kusan 3 × 10 - 4 Tor.An cika Argon a cikin ɗakin don dan rage matsa lamba don samar da plasma lokacin da baka ya buga.Sa'an nan kuma ruwan narkakkar yana motsawa ta hanyar plasma na al'ada.Sannan ana maimaita tsarin sau da yawa don cimma daidaituwar abun da ke ciki.
A kowane hali, ƙalubalen dumama abubuwan haɗin gwiwa yana ƙoƙarin samar da hypoeutectic.Saboda jinkirin saurin sanyaya, siffa da girman block ingots suna da iyaka, kuma yana da tsada sosai don amfani da wannan fasaha don kera manyan allunan entropy.A m hadawa hanya ya ƙunshi inji alloying da m ƙarfafa tafiyar matakai.Wasu nazarin sun nuna cewa haɗakarwa ta injina tana samar da daidaituwa da daidaituwar microstructure na nanocrystalline.Hanyar haɗewar iskar gas ta haɗa da epitaxy na ƙwayoyin ƙwayoyin cuta, jigon sputtering, jigilar Laser pulsed (PLD), tuhun tuhu da jigon atomic Layer.
