Abstract

Aluminium (Al) merupakan logam ringan, mempunyai ketahanan korosi yang baik dan hantaran listrik yang baik dan sifat-sifat baik lainnya sebagai sifat logam, selain itu aluminium juga mempunyai sifat mampu membentuk (machinability). Tembaga (Cu) ditambahkan untuk meningkatkan kekuatan material tersebut, makin tinggi kadar tembaga maka makin banyak fasa yang terbentuk, sehingga kekerasan dan kekuatan paduan akan meningkat. Selain itu, peningkatan komposisi tembaga di dalam paduan Al-Si-Cu dapat juga meningkatkan sifat ketahanan korosi dan sifat ketahanan aus. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi tembaga terhadap sifat mekanik dan struktur mikro dari pengecoran Al-Si. Hasil uji hardness rockwell menunjukkan bahwa semakin banyak unsur Cu yang ditambahkan pada paduan Al-Si maka semakin besar nilai kekerasan dan kekuatan paduan. Hasil pengujian impact charpy didapat nilai impact pada sampel 1 yaitu 0,0307 J/mm2 dan sampel 2 yaitu 0,0129 J/mm2. Hasil pengujian tensile kekuatan tarik sampel 1 yaitu 93.50  N/mm2, sampel 2 yaitu 39.39 N/mm2, dan  sampel 3 yaitu 33.60 N/mm2.

Abstract

In this study, molecular dynamics simulations (MD) will be applied to modelling the Al4C3-aluminum interface in aluminum nanocomposite, Al4C3 is an interface that results from the shaker mill process which becomes a bridge that plays an important role in Carbon particles with Aluminium Matrix and Based on observations from the TEM characterization, it is found that the relationship between Al orientation to Al4C3 is (111) (002) (220). The characteristics of the interface between Aluminum matrix and Al4C3 will be analyzed using uniaxial tension and shear test simulation. The atomic potential used in this simulation is the embedded atomic method (EAM) for Al, empirical-order intermolecular potential (AIREBO) for C and lennard jones for the reaction of Al-C atom. The result shows that, the interface orientation is Al matrix (002) || Al4C3 (003) has the highest interface strength compared to Al matrix (111) || Al4C3 (003) and Al matrix (200) Interface orientation || Al4C3 (003). Results from the molecular dynamics simulations are also discussed with analytical results obtained experimental
