The annealed AA-6063 alloy was processed up to three passes of MDF at ambient temperature. Three passes of this process were also applied to the solution-treated AA-6063 at ambient temperature and 177 ◦C. Microstructural investigations demonstrated that the MDF process led to a significant reduction in the average grain size as well as a considerable increase in the fraction of low angle grain boundaries. Texture analysis revealed that copper and Goss textures were mainly developed within the annealed and solution-treated samples of AA-6063, respectively.

  • Welding of Magnesium Alloys
    Chapter 6 Welding of Magnesium Alloys Parviz Asadi, Kamel Kazemi-Choobi and Amin Elhami Additional information is available at the end of the chapter http://dx.doi.org/10.5772/47849 1. Introduction Magnesium is the sixth most abundant element on the Earth’s surface, with virtually inex- haustible supplies in the oceans. It is the third most plentiful element dissolved in seawater, with an approximate concentration of 0.14% (Busk, 1987). Over recent years the industrial output of magnesium alloys has been rising by almost 20% per annum. Magnesium and its alloys, as the lightest structural material, are about 40% lighter than aluminium and as much as about 78% lighter than steel. It is demonstrated that using magnesium alloys results in a 22–70% weight reduction, compared to using alternative materials (Kulekci, 2008). Magne- sium alloys have excellent specific strength, excellent sound damping capabilities, good cast-ability, hot formability, excellent machinability, good electromagnetic interference shielding, and recyclability (Haferkamp et al., 2000), (Mordike and Ebert, 2001), (Pastor et al., 2000). Moreover, magnesium ignites with difficulty in air due to its high heat capacity. Some disadvantages of magnesium are presented based on the following, Low elastic modulus; High degree of shrinkage on solidification; High chemical reactivity. Additionally, these alloys have limited fatigue and creep resistance at elevated temperatures (Mordike and Ebert, 2001). Because of the hexagonal close-packed (HCP) crystal structure, magnesium alloys also have a limited ductility and cold workability at room temperature (Sanders et al., 1999). These alloys have about the same corrosion resistance in common environments as mild steel, but are less corrosion resistant than aluminium alloys (Busk, 1987).

One such area, where alloys with complex compositions are already found, is in filler metals used for joining. In soldering (<450 ◦C) and brazing (>450 ◦C), filler metal alloys are taken above their liquidus temperature and used to form a metallic bond between two components, which remain both unmelted and largely unchanged throughout the process.

In this study, TIG welding parameters influence on weldability of 5052 aluminium alloy specimens with dimension of 100mm long x 50mmwide x 2.5mmthick is investigated. The welding parameters such as arc voltage, welding current, welding speed, gas flow rate and heat input are taken into account which influence the depth of penetration measured after welding. Keywords: AA5052, Arc voltage, Welding current, Gas flow rate, Heat Input, Welding speed. I. INTRODUCTION TIG welding was demonstrated first by Russell Meredith in 1930 during second world war for welding aluminium and magnesium in aircraft industry [1]. Welding technology has obtained access virtually to every branch of manufacturing; to name a few, ships, rail road equipments, building construction, boilers, launch vehicles, pipelines, nuclear power plants, aircrafts, automobiles, pipelines. Welding technology needs constant upgrading and with the widespread applications of welding [2]. Welding is a fabrication or sculptural process that joins materials, usually metals, or thermoplastics, by causing coalescence.
