Ngokuchongwa kweCopper enye yeCrystal

I-OCC Ohno Continuous Casting yeyona nkqubo iphambili yokuvelisa iSingle Crystal Copper, yiyo loo nto xa i-OCC 4N-6N iphawulwa, abantu abaninzi bacinga ukuba yi-single crystal copper. Akukho mathandabuzo ngayo, nangona kunjalo i-4N-6N ayimeli, kwaye sibuziwe ukuba singayingqina njani into yokuba i-copper yi-single crystal.

Enyanisweni, ukuchonga i-single crystal copper ayilula kwaye kufuna ukuqwalaselwa ngokubanzi kwiinkalo ezininzi.

Okokuqala, ngokweempawu zezinto ezibonakalayo, uphawu olukhulu lwe-single crystal copper kukuba zimbalwa kakhulu iikhompawundi kwaye inesakhiwo se-columnar crystal. Olu phawu luthetha ukuba xa ii-electron ziqhutywa kwi-single crystal copper, akukho kusasazeka okuninzi, nto leyo ebangela ukuba kubekho umbane oqhuba kakuhle. Kwangaxeshanye, isakhiwo se-columnar crystal columnar senza i-single crystal copper ikwazi ukumelana nokuguquguquka xa ixinezelekile, nto leyo ebonisa ukuguquguquka okuphezulu.

Kwinkqubo yokuchonga yokwenyani, ukujonga ngemicroscope yindlela esetyenziswa kakhulu. Kodwa kufuneka kuqatshelwe ukuba kunzima ukwahlula okanye ukuqinisekisa ubhedu lwekristale enye kuphela ngemicroscope. Oku kungenxa yokuba iimpawu zobhedu lwekristale enye azisoloko zibonakaliswa ngokucacileyo kwinqanaba lemicroscope, kwaye iimeko ezahlukeneyo zokujonga kunye namanqanaba obuchwephesha zinokuchaphazela ukuchaneka kweziphumo.

Nantsi umfanekiso ofunyenwe nge-microscope

Sisebenzise intonga yobhedu eyi-8mm ukwenza uphononongo olunqamlezileyo kwaye sinokubona ukukhula kweekristale zekholamu. Nangona kunjalo, le yindlela yokuncedisa kuphela kwaye ayinakukwazi ukumisela ngokupheleleyo ukuba le nto yikristale yobhedu enye.

Okwangoku, lonke eli shishini lijongene nengxaki yokuba kunzima ukuqinisekisa ngokuthe ngqo ubhedu lwekristale enye. Kodwa singandisa isiseko sokugweba ubhedu lwekristale enye ngokusebenzisa izixhobo ezithile zemveliso kunye neenkqubo. Umzekelo, izixhobo zobhedu eziveliswa zizitofu zokunyibilikisa ikristale enye zinokuqinisekisa kakhulu ukuba zinesakhiwo sekristale enye. Kuba olu hlobo lwezixhobo lunokubonelela ngeemeko ezithile zokukhula kobhedu lwekristale enye, olunceda ekwakhiweni kweekristale zekholamu kunye nokunciphisa imida yeenkozo.

I-Vaccum ephezuluizixhobo zokuphosa eziqhubekayo

Ukongeza, ukufunyanwa kwesalathiso sokusebenza kukwayindlela ebalulekileyo yokuchonga ubhedu oluyikristale enye. Ubhedu oluyikristale enye oluhle kakhulu lubonisa ukusebenza okugqwesileyo ekuqhubeni nasekuguquguqukeni kombane. Abathengi banokubonelela ngeemfuno ezithile zokuqhuba kunye nokwandiswa. Ngokubanzi, ubhedu oluyikristale enye lunokuqhuba okuphezulu kwaye lunokuhlangabezana neemfuno ezithile zamanani. Kwangaxeshanye, ukwandiswa kwalo nako kulungile kwaye akulula ukuliqhekeza xa lixinezelekile. Ubhedu oluyikristale olunye kuphela olunokufikelela kwinqanaba eliphezulu kwezi mpawu zokusebenza.

Ukuqukumbela, ukuchonga ubhedu oluyikristale enye yinkqubo enzima efuna ukuqwalaselwa ngokubanzi kwezinto ezininzi ezifana neempawu zezinto eziphathekayo, izixhobo zemveliso kunye neenkqubo, kunye neempawu zokusebenza. Nangona okwangoku kungekho ndlela ichanekileyo yokuqinisekisa ngokuthe ngqo ubhedu oluyikristale enye, ngokusebenzisa ezi ndlela zidibeneyo, ubhedu oluyikristale enye lunokuchongwa ngokuthembekileyo ukuya kwinqanaba elithile. Kwizicelo ezisebenzayo, kufuneka siqhubeke sihlola kwaye siphucule iindlela zokuchonga ukuqinisekisa umgangatho kunye nokusebenza kobhedu oluyikristale enye kunye nokuhlangabezana neemfuno zamacandelo ahlukeneyo.
