    Materials Science. Non-Equilibrium Phase Transformations., Vol. 5 (2019), Issue 1, pg(s) 26-27

    The aim of this work is to present the influence of anodic surface treatment parameters on thickness and structure of an anodic layer formed on aluminum products.
    The materials used in this study are the aluminum products from Alumil Company in Albania. The analyses of samples were performed using Optical Microscopy (Leica DMI 5000 M) for characterization of macrostructure of anodizing layer and Vickers micro-hardness (HMV-2 tester) of non-anodized aluminum products and anodized aluminum products. Aluminum product of the series A6060 are taken in Alumil Company in Albania. Comparing the results in this research (analyses) we have concluded the characteristics of anodizing layer in the aluminum product, which have improved and increase their surface and product performance.

    FINITE ELEMENT MODELING OF INCREMENTAL SHEET METAL FORMING OF ALUMINUM ALLOY AL 1100

    Machines. Technologies. Materials., Vol. 11 (2017), Issue 8, pg(s) 397-400

    Incremental sheet metal forming has been well-known as one of the flexible methods of forming metallic sheets, suitable for the production of prototypes or small batch sizes. Apprehending the deformation method in forming processes and selection of route parameters to avoid part failure are of vital importance, because marketing needs standard sound parts in a shortest possible time. This paper presents the study on the use of finite element modeling of incremental sheet metal forming of Al 1100 aluminum alloy to investigate the effect of tool diameter and step over on the forming induced stresses, part thickness distribution and forming forces. The results of finite element analysis are compared with experimental data while producing truncated pyramid parts. It has been shown that the developed finite element model is capable of providing reliable results in the prediction of the final thickness of the part, which matches the experimental results with a maximum discrepancy of 8%.
