Uburyo bwo gukora bwa entropiya yo hejuru

Vuba aha, abakiriya benshi babajije ibijyanye na entropie alloy.Nubuhe buryo bwo gukora bwa entropie alloy?Noneho reka tubisangire nawe mwanditsi wa RSM.

Uburyo bwo gukora amavuta menshi ya entropiya arashobora kugabanwa muburyo butatu: kuvanga amazi, kuvanga bikomeye no kuvanga gaze.Kuvanga amazi birimo gushonga arc, gushonga gushonga, gushonga induction, Bridgman gukomera hamwe no gukora inyongeramusaruro.Mu bushakashatsi, ibinini byinshi bya entropiya bikozwe no gushonga arc, kandi gushonga arc bibaho mugihe cya vacuum gifunze argon ibidukikije byo guta ibishishwa byashongeshejwe.Amavuta azakorwa arayungurura akoresheje vacuum arc melter.Imashini yo gushonga ya kole ifite ibikoresho bya buto.Gushonga bikorwa hifashishijwe tungsten ikoreshwa na electrode ikoresha ibice byicyuma nkibiciro kugirango ikubite arc.Icyumba noneho gipompa hifashishijwe pompe ya turbomolecular na pompe itoroshye kugirango ubone hafi 3 × 10 - 4 Tor.Argon yuzuye mu cyumba kugirango igabanye gato umuvuduko kugirango ikore plasma mugihe arc ikubise.Noneho pisine yashongeshejwe na plasma isanzwe.Inzira noneho isubirwamo inshuro nyinshi kugirango ugere kuburinganire.

Ibyo ari byo byose, ikibazo cyo gushyushya ibice hamwe gikunda gukora hypoeutectic.Bitewe n'umuvuduko ukonje utinze, imiterere nubunini bwibikoresho byo guhagarika ni bike, kandi birahenze cyane gukoresha ubwo buhanga kugirango ukore amavuta menshi ya entropiya.Inzira ikomeye yo kuvanga ikubiyemo gukanika imashini hamwe nuburyo bwo guhuza ibikorwa.Ubushakashatsi bumwe bwerekana ko kuvanga imashini bitanga microstructure ya nanocrystalline imwe kandi ihamye.Inzira yo kuvanga gazi ikubiyemo epitaxy ya molekulari, gusohora ibintu, gusunika laser (PLD), kubika imyuka no kubika atome.
