Özet:

 Nickel is a metal widely used in many industrial applications, but despite its superior properties, it also has some shortcomings. Carbon-based structures can be important reinforcement elements in improving the properties of metals. By providing a balance between the high corrosion resistance, high electrical conductivity and good magnetic properties of the nickel material and the lightness and high strength of carbon-based structures, a material with advanced properties can be obtained. Therefore, in this study, a new Nickel-Carbon nanostructure supported by a covalently bonded graphene-carbon nanotube CNT skeleton structure is presented. Additionally, three material designs with different geometric dimensions Ni-G-CNT5,5, Ni-G-CNT10,10 and Ni-G-CNT15,15 were designed to determine the mechanical properties and properties of the structures in all directions. is to investigate the underlying deformation mechanisms. According to the results, it was observed that G-CNT structures increased the tensile and compressive behavior of the Ni structure in the CNT direction. For tensile loading in the CNT direction, as the CNT diameter decreases, the elastic modulus of the hybrid structures increases, while the maximum stress values are independent of the CNT diameter. As the CNT diameter increases, the ductility of the structures increases. In terms of compressive strength, it has been observed that in the linear region, as the CNT diameter increases, the strength generally increases and in the condensation region, it exhibits better compressive strength. With this study, an anisotropic nanostructure that is lighter and can exhibit higher tensile strength compared to the Ni structure is presented.

 Nikel, birçok endüstriyel uygulamada yaygın olarak kullanılan bir metaldir, ancak üstün özelliklerinin yanı sıra bazı eksik yanları da mevcuttur. Metallerin özelliklerini iyileştirmede karbon temelli yapılar önemli takviye elemanı özelliği göstere bilmektedir. Nikel malzemesinin yüksek korozyon direnci, yüksek elektrik iletkenliği ve iyi manyetik özelliği ile karbon bazlı yapıların hafiflik ve yüksek mukavemeti arasında bir denge sağlayarak gelişmiş özelliklere sahip bir malzeme elde edilebilir. Bu nedenle, bu çalışmada, kovalent olarak bağlı grafen- karbon nanotüp KNT iskelet yapısı ile desteklenmiş yeni bir nikel-Karbon nanoyapısı sunulmaktadır. Ayrıca, farklı geometrik boyutlara sahip üç malzeme tasarımı Ni-G-CNT5,5, Ni-G-CNT10,10 ve Ni-G-CNT15,15 yapılarak yapıların tüm doğrultulardaki mekanik özellikleri ve altta yatan deformasyon mekanizmalarını araştırmaktır. Sonuçlara göre, G-CNT yapılarının Ni yapısının çekme ve basma davranışını KNT doğrultusunda artırdığı görülmüştür. KNT doğrultusunda çekme yüklemeleri için KNT çapı azaldıkça hibrit yapıların elastik modülü artarken maksimum gerilme değerleri KNT çapından bağımsızdır. KNT çapı arttıkça ise yapıların süneklikleri artmaktadır. Basma dayanımı açısından ise lineer bölgede genel olarak KNT çapı arttıkça dayanımın arttığı yoğunlaşma bölgesinde ise daha iyi basma dayanımı sergilediği görülmüştür. Bu çalışma ile Ni yapısına kıyasla daha hafif ve daha yüksek çekme dayanımına sergileyebilen anizotropik bir nanoyapı sunulmuştur.
