Prof. Dr. Ghulam Hussain Supervisor Examining Committee 1. Prof. Dr. Fuat Egelioğlu __________________________ 2. Prof. Dr. Majid Hashemipour __________________________ 3. Asst. Prof. Dr.Ghulam Hussain __________________________ ABSTRACT Single point incremental forming (SPIF) process is considered as a cost-effective method to fabricate sheet metals because there is no need for dedicated dies which are used in other conventional processes. Due to the capability of forming sheets on CNC machines, the flexibility of this process is high which allows the operator to modify the geometry of the product much easier than the other methods like stamping. This study is carried out to investigate the effects of different forming parameters on the mechanical properties and microstructures of formed parts. The effects of wall angle, feed rate, spindle speed and lubrication are explored on AA5754 and AA6061 Aluminium Alloys.

In this emphasis in this section than metal to- metal and process tool will generate the pressure and polymer-to-polymer welding, since metal-to- temperature and form solid state weld. This process polymer is a novel technique and there are fewer is suitable for joining different materials, different publications in this area [15]. The schematic mechanical and chemical properties, and different representation of FSW process is shown in Fig. material structures. Fusion welding processes 1. exhibits poor weldability by Welding of dissimilar aluminium alloys. Because of thin oxide layer formation, oxide layer tends to thicken at higher temperatures on the surface of aluminium alloys. This review addresses the Friction stir welding overview which includes the basic concept of the process, microstructure formation, influencing process parameters, typical defects in FSW process and some recent applications. The paper will also discuss some of the process variants of FSW such as Friction Stir Processing. Keywords - Tool rotational speed, Friction Stir welding, dissimilar aluminium alloy. 1.

Box 1346 Ann Arbor, Ml 48106-1346 The Production of Metal Mirrors for use in Astronomy Abstract This thesis demonstrates the possibility of manufacturing larger mirrors from nickel coated aluminium with a considerable cost and risk benefits compared to zero expansion glass ceramic or borosilicate. Constructing large mirrors from aluminium could cut the cost of production by one third. A new generation of very large telescopes is being designed, on the order of 100 meters diameter. The proposed designs are of mosaic type mirrors similar to the Keck Telescope primary. The enormous mass of glass required inhibits the construction, simply by its cost and production time. Very little research has been done on the processes involved in the production of large metal mirrors.

However, car manufacturers have to remain in competition with peers and design their products innovatively that fulfil the new regulations too. Nevertheless of various different approaches to improve fuel economy such as enhancing fuel quality, development of high performance engines and fuel injection system, weight reduction is one of the encouraging approaches. With 10% weight reduction in passenger cars, the fuel economy improves by as much as 6–8%. KEYWORDS: Carbon Fibre, Magnesium, Aluminium, Titanium, light-weight body materials, poly-acrylonitrile I. INTRODUCTION Car body design in view of structural performance and weight reduction is a challenging task due to the various performance objectives that must be satisfied such as vehicle safety, fuel efficiency, endurance and ride quality.

  • Elasto-Viscoplastic Properties of Aa2017
    TASK QUARTERLY 15 No 1, 5–20 ELASTO-VISCOPLASTIC PROPERTIES OF AA2017 ALUMINIUM ALLOY ANDRZEJ AMBROZIAK, PAWEŁ KŁOSOWSKI AND ŁUKASZ PYRZOWSKI Department of Structural Mechanics and Bridge Structures, Faculty of Civil and Environmental Engineering, Gdansk University of Technology, Narutowicza 11/12, 80-233 Gdansk, Poland ambrozan, klosow, lpyrzow @pg.gda.pl { } (Received 18 November 2010; revised manuscript received 21 February 2011) Abstract: This paper describes a procedure for the identification of material parameters for the elasto-viscoplastic Bodner-Partom model. A set of viscoplastic parameters is identified for AA2017 aluminium alloy. The evaluation of material parameters for the Bodner-Partom consti- tutive equations is carried out using tensile tests. Numerical simulations of material behaviour during constant strain-rate tests are compared with direct uniaxial tensile experiments. A review of the models applied to concisely describe aluminium alloy is also given. Keywords: AA2017, viscoplasticity, Bodner-Partom, tensile tests 1. Introduction Aluminium alloy is commonly used in the aircraft industry, building and construction industry, electricity, packaging, transportation, etc. It is an alloy of intermediate strength and good ductility. The main alloying elements are copper, magnesium, zinc, silicon, manganese and lithium. In the case of AA2017 aluminium alloy, the main alloying element is copper, see e.g. [1]. The selection of constitutive models is one of the most important prob- lems, which is considered before other aspects of structural analysis. Different approaches to constitutive modelling of the behaviour of aluminium alloys (such as nonlinear elastic, viscoplastic, viscoelastic) can be considered. Very often, the undertaken approach depends not only on the material properties, but also on the type of loading under consideration.

MAJEWSKI* BRAZE WELDING TIG OF TITANIUM AND ALUMINIUM ALLOY TYPE Al – Mg The article presents the course and the results of technological tests related to TIG-based arc braze welding of titanium and AW-5754 (AlMg3) aluminium alloy. The tests involved the use of an aluminium filler metal (Al99.5) and two filler metals based on Al-Si alloys (AlSi5 and AlSi12). Braze welded joints underwent tensile tests, metallographic examinations using a light microscope as well as structural examinations involving the use of a scanning electron microscope and an X-ray energy dispersive spectrometer (EDS). The highest strength and quality of welds was obtained when the Al99.5 filler metal was used in a braze welding process. The tests enabled the development of the most convenient braze welding conditions and parameters. Keywords: braze welding, aluminium alloy, titanium, mechanical properties of braze welded joints, structural properties of braze welded joints, braze welding parameters. 1. Introduction previous research conducted at Instytut Spawalnictwa and focused on brazing titanium and stainless steels [16, 17].
