Deney 1. Planlama <ol><li> Şekil 1&#39;de gösterildiği gibi bir kurban desen (bir yolluk sistemi ile sekizli kafes yapısı) bilgisayar destekli tasarım (CAD) yazılımı kullanarak çizin ve bir STL dosya biçimi olarak CAD modeli kaydedin. Not: Kurban desen sonunda döküm için erimiş olacak bir yolluk sistemi ile sekizli kafes yapısının entegre bir kalıptır. Kurban desen sekizli kafes yapısı ve yolluk sistemi hem de içerdiğinden, tam olarak sekizli makas kendisi temsil etmez. ...

Geleneksel metal döküm için, pürüzsüz ve kalıp boşluğu içinde &#39;laminer&#39; de aerodinamik erimiş metalin akışını tutmak ve oldukça genellikle türbülanslı akış 27 gözlenen düzensiz ve ajite akışını önlemek için önemlidir. Duruma göre, uygun bir şekilde kafes kalıp boşluğu &#39;laminer&#39; içindeki erimiş metalin akışını sağlamak için bir santrifüj kolun dönüş hızı ile bağlantılı spru sisteminin giriş tasarımı önemlidir. ...

Hücresel metaller katı dikmeler veya plakaların bağlantılı bir ağ oluşur metaller ve 1 boşlukları ile karmaşık mikro-mimarisi var. Örnekler hem i) rastgele yapılandırılmış stokastik köpükleri ve dahil ii) periyodik olarak iki boyutlu (2D) petekler ve üç boyutlu (3D) kafes kafes yapıları emretti. Onlar nedeniyle yüksek spesifik sertlik ve kuvvet 1-3 ve yüksek spesifik esneklik 4-5, darbe yükleme 6, akustik yalıtım 7, ısı kırıcı yapılar ve ısı değiştirici 8 olası tasarım için mükemmel enerji emilimi dikkat aldık. Özellikle periyodik olarak sipariş kafes yapıları iç gözenekli ağ geometrisi kontrol etmek için bir yeteneği ile üstün özellikler mühendisi potansiyeline sahiptir. Onların kompleks, iç gözenekli ağ geometrisine, geleneksel eksiltici machinin kullanarak selüler metallerin imalatı zordurörn. Böyle araştırmacılar hücresel metaller imal etmek alternatif yöntemler aramaya başladılar gibi: Sıvı metal oluşturan gaz veya üfleme maddeleri ile metal tozu karıştırma stokastik metal formları 9 imalatı için incelenmiştir. Nedeniyle hücre topoloji üzerinde kontrol eksikliği nedeniyle, mekanik özelliklerini uyarlamak zordur. Alternatif olarak, periyodik olarak sipariş hücresel metaller için imalat yöntemleri araştırıldı: periyodik yapılar 10 oluşturmak için onlara katılarak, ardından bir oluklu şekle metalin ince yaprak damgalama, yapıştırma tekstil 13 imal metal levhalar 11, ekstrüzyon 12, dokuma ve yanan metal elyaflar yaptı. Bu üretim yöntemleri tekrarlanabilir kalıpları sunuyoruz olsa da, desenler hala düzlemsel yönde sınırlıdır. 3D model tekrarlama oluşturmak için bir çaba, araştırmacılar katkı imalat (AM) kullanmaya başladı; örneğin, Selektif Lazer Erime (SLM) 14, Elektron Işını Erime (EBM) <sup&gt; 15 ve Direct-Metal Lazer Sinterleme (DMLS) 16. Karmaşık kafes geometri sipariş 3D imal etme yeteneği rağmen, hala bazı sınırlamalar vardır vardır: zorluk lazer ya da elektron erime sırasında yüksek ısı iletkenliği ve yüksek optik yansıtma 17, yüksek termal artık gerilme 18 &#39;balling&#39; fenomeni ile zayıf yüzey ile metalleri kullanarak 19, anizotropik özellikleri katmanlı imalat, tahıllar, toz boyutu, güç ve lazer ya da elektron ışını 15, yüksek enerji tüketimi, vb tarama hızı anizotropik oluşumu kombine etkisinin sebep olduğu parçaları 20-21. Metal döküm ile polimer esaslı AM birleştiren kafes metalleri üretmek için alternatif bir yöntem sağlayabilir. Biri bu &quot;dolaylı AM&quot; çağırabilir. Dolaylı AM yukarıda belirtilen metallerin doğrudan AM teknik sorunların üstesinden gelmek için bir çözüm sağlayabilir. Çeşitli çabalar ma olmuşturBir kum tozu ile birlikte bir kafes alaşım 22-25 veya kum döküm imal etmek, örneğin erimiş birikim modelleme (FDM) ile kombine bir döküm; de dolaylı yerçekimi bazlı döküm 22-25 polimerlerin 3D baskı birleştirerek AM kullanarak kafes metalleri üretmek için AM 23 tabanlı. Onlar kafes yapısal kalıplar 25-26 keskin köşelere sahip ağ yapıları karşılaştıklarında erimiş metaller ani katılaşma neden Misrun ve gözeneklilik - yerçekimi bazlı döküm aşmak için bir teknik meydan kalır gibi görünüyor. Kafes yapı kalıpların nispeten geniş bir yüzey alanı da erken katılaşması 25-26 sonuçlanan ani soğutma katkıda bulunduğu görülmektedir. 3D baskılı kafes kurban polimer modeli tarafından yapılan bir kafes kalıp boşluğuna santrifüj döküm - Bu çalışmada, biz bir kafes metal imalat sırasında Misrun üstesinden gelebilir alternatif dolaylı AM öneriyoruz. Bir dijital kullanınIşık işleme (DSP) Al ve Cu alaşımlarının santrifüj döküm ardından kafes yapısal kurbanlık desen oluşturmak için tabanlı 3D baskı yöntemi. Bu çalışmanın amacı, kompleks bir şekle ve ince bir duvar kalınlığına sahip 3D örgü metal üretimi ile ilgili ayrıntılı bir protokol sunmaktır. Bu sürecin ana katkısı kafes metal üretimi için düşük üretim maliyeti ile malzeme seçimi genişletmek için bir fırsat vermektir.

indirect fabrication of lattice metals with thin sections using centrifugal casting

3D kafes metal üretimi için tipik yöntemlerden biri gibi Selektif Lazer Erime (SLM) ve Elektron Işını (EBM) Erime direkt metal katkı üretim (AM) işlemidir. potansiyel işleme kapasitesi olmasına rağmen, doğrudan AM yöntemi, yüksek bir maliyet son ürünlerin düşük yüzey arasında, bunlarla sınırlı malzeme seçimi, yüksek termal stres ve parça anizotropik özellikleri gibi çeşitli dezavantajları vardır. Biz 3D kafes metalleri üretmek için düşük maliyetli bir yöntem önerilmektedir. Örneğin sekizli kafes 5 mm bir birim hücre uzunluğa ve bir hücre duvarı kalınlığı olan Al ve Cu alaşımlarından yapılmış, bu çalışmanın amacı, kompleks bir şekle ve ince bir duvar kalınlığına sahip 3D örgü metal üretimi ile ilgili ayrıntılı bir protokol sunmaktır 0.5 mm. Genel olarak deney prosedürü, sekiz bölüme ayrılmıştır: geçici desen (a) 3D baskı, (b) destek malzemeleri (c) destek malzemeleri kalıntısının çıkarılması Çıkış eriyik (d) model assembly (e) Yatırım (f) nihai ürünler için kurban desenleri (g) santrifüj döküm (h) post-processing ve burn-out. Önerilen dolaylı AM tekniği ultra-hafif kafes metal üretimi potansiyeline sunar;. Örneğin, kafes yapılar, Al alaşımları ile. Süreç parametreleri düzgün dolaylı AM tekniği ile sekizli kafes metallerin nihai ürünleri gözlemleyerek, malzeme ve kafes geometrisine bağlı kontrol edilmelidir anlaşılmaktadır.

Şekil 1 &#39;de gösterildiği gibi, bir protokol bölümünde açıklanan dolaylı katkı üretim kullanarak, Al ve Cu alaşımları, imalat sekizli kafes metaller için kullanılan bütün döküm yöntemi Şekil 2&#39;de özetlenmiştir işlemi sekiz bölümden oluşur.:. (A) geçici destek malzemesi (c) destek malzemesi (d) model montaj (e) kurban desenleri (g) santrifüj döküm, ve (h) yatırım (f) burn-out kalıntısının çıkarılması desen ...
