For my grandchildren: ALEXANDRE ROMAIN ALEXANDRA This page is intentionally left blank Foreword With an annual consumption of 35 million metric tons, aluminium is one of the world’s most commonly used metals. Its lightness coupled with its strength, conductivity, barrier properties and its excellent corrosion resistance have all been and continue to be its most important advantages and the main reasons for the continued growth in the usage of aluminium. Aluminium’s lightweight performance delivers great benefit in transport applications such as aerospace, cars, ships, trains and buses. The metal’s intrinsic characteristics help give automotive and other transport users improved driving performance as well as increasing fuel economy and reducing emissions. Another significant advantage of aluminium is its corrosion resistance. This characteristic is valuable for products used in architecture, construction, civil engineering, transport, heat exchangers and many other applications. From its early industrial days aluminium was used in many areas of transportation, however it was not until scientists developed commercially available aluminium magnesium alloys in the 1930’s that aluminium was used in shipbuilding and other harsh operating conditions. The alloys developed by these metallurgists as well as having excellent corrosion resistance are also weldable, which led to them being firmly established as a key construction material by ship and high speed ferry builders. New alloy development has been critical throughout the history of aluminium, establishing many new market applications. Improving corrosion performance has been a key focus of this metallurgical development. In the 1970’s alloys were developed with very good thermal conductivity, combined with excellent resistance to engine coolants. This combination means that it was possible to manufacture heat exchangers that were cheaper and of course lighter than the traditional copper versions. More recently new alloy developments have included automotive, aerospace, desalination of sea water, renewable energy and maritime applications, as well as many civil engineering and industrial applications. Christian Vargel is renowned as one of the Aluminium industry’s leading experts in aluminium corrosion. During his long and successful career within the Pechiney group, his expertise in corrosion was valuable in the product development of key markets such as automotive, marine and other transport applications. He has also given many presentations on the corrosion resistance of aluminium, and has contributed to many of Pechiney’s technical documents and brochures, such as “Aluminium and the Sea” and “Aluminium in Industrial Vehicles”. His first book Le comportement de l’aluminium et de ses alliages (The behaviour of aluminium and its alloys) was published by Dunod in 1979. vii viii Foreword Christian Vargel’s second book Corrosion de l’aluminium was first published in French in 1999 and I am delighted that it is now being published in English, thus enabling this excellent work to be more accessible to a wider audience. The author’s practical approach has resulted in what I believe will become a standard reference for aluminium users seeking to understand corrosion characteristics. The work provides an excellent manual, advising of the best ways of working with aluminium including the selection of alloys, design principles and operating conditions. I believe the book will become a valuable text for many engineers and technicians who work and use aluminium. MICHEL JACQUES President, Alcan Engineered Products April 2004 Foreword to the Original French Edition With an annual consumption of 25 million metric tons, aluminium is the second most commonly used metal in the world after steel. Its lightness is very often the most important advantage for the commercial development of aluminium, which explains why it is extensively used for ground transport, aerospace and shipbuilding. This is also the reason why the automotive industry is currently very interested in aluminium: lightness is becoming a priority.

    Preliminary Development of a PPAM Actuated Pediatric Prosthetic Ankle Connor McNamara-Spackman A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science (Bioengineering) at the University of Otago, Dunedin, New Zealand. February 2021 Abstract The purpose of this research was to develop a preliminary design of a powered pediatric prosthetic ankle. Previous research identified the health risk of improper gait cycle and the lack of powered prosthetic ankle options for children. Costs for powered prosthetic ankles are too high (upwards of $5000 NZD), the sizes are too large and the weight is too significant for a child to benefit from. Current technologies for ankle joint actuation and materials for the prosthetic structure were evaluated and a conclusion of utilizing PPAMs was chosen due to their ability to generate the required 300 N of contraction force. CAD was used to model the structure of a prosthetic ankle and evaluate the FOS of the different material combinations while under static loading and fatigue simulations. HDPE and UHMWPE failed to withstand the simulations, while the aluminium alloy and stainless steel showed minimal faults from the simulations. MatLab was used to simulate the desired PPAM dimensions of 100 mm to determine the contraction force and contraction percentage that can be generated by the PPAM. The smallest PPAM found in research was 110 mm and showed promising results from their mathematical modeling. The overall height of the prosthetic was no greater than 110 mm and the membrane length of the PPAM was no greater than 100 mm, while successfully producing more than 300 N during contraction.

Paredes-Dugarte, Benjamín Hidalgo-Prada Material Science Department, Materials Characterization Laboratory. Research Institute of Biomedicine and Applied Sciences “Dra. Susan Tai”, University Ave., Cumaná, Sucre 6101, Venezuela. Abstract In this study, a statistical evaluation was made of the susceptibility to pitting corrosion, using the pitting factor criteria. Specimens were cut in size of 15 cm x10 cm of AA3003 aluminium sheet of temper H14, H16 and H18 of national production. Afterwards, they were exposed to a salt spray during 72, 144, 216, 288 and 360 hours continually, according to ASTM B117 standard. After salt spray test was observed pitting attack in all specimens regardless of the exposure time and the degree of deformation (temper) of material. The surfaces of the corroded specimens were analyzed by optical interferometry. The parameters evaluated in each field were: roughness (Rms), peak-valley distance (PV) and the lowest point of all peaks (V). A pitting factor of the order of 4 was calculated, indicating a highly localized corrosion process for this commercial aluminium alloy 3003 in saline environment. © 20152014 TheThe Authors. Authors.

  • Multi-Response Optimization of Process Parameters by Taguchi Grey Relational Analysis for Dissimilar Thickness Friction Stir Process Corner Weld Aa5086 Alloy
    Journal of Engineering Science and Technology Vol. 13, No. 10 (2018) 3297 - 3312 © School of Engineering, Taylor’s University MULTI-RESPONSE OPTIMIZATION OF PROCESS PARAMETERS BY TAGUCHI GREY RELATIONAL ANALYSIS FOR DISSIMILAR THICKNESS FRICTION STIR PROCESS CORNER WELD AA5086 ALLOY MANIGANDAN KRISHNAN*, SENTHILKUMAR SUBRAMANIAM School of Mechanical Engineering, VIT University, Vellore, India *Corresponding Author: [email protected] Abstract This paper presents the multi-response optimization of friction stir corner welding process for dissimilar thickness AA5086 aluminium alloy plates. The corner joint of AA5086 aluminium alloy plates of thicknesses of 6 mm and 4 mm was welded by Friction Stir Welding (FSW) process. The FSW experiments were conducted agreeing to the L9 orthogonal array. Three FSW process parameters: tool traverse speed (100, 150 and 190 mm/min), rotational speed (900, 1000 and 1100 rev/min), and plunge depth (0.1, 0.2, and 0.3 mm) were related with weld tensile strength and hardness. The Analysis of Variance (ANOVA) was used to determine the percentage contribution of each input parameter on the weld quality. Taguchi Grey Relational Analysis is used to optimize and order the FSW process parameters. Conferring to the results of the analyses, the optimal welding condition was determined as 1000 rev/min for tool rotational speed, 150 mm/min for traverse speed and 0.1 mm for tool plunge depth. The percentage contribution of the traverse speed (54%) revealed a significant influence compared to tool rotational speed (21%) and plunge depth (13%). The microstructures of various zones were observed and analysed. Tensile tests were conducted and the fracture was observed at heat affected zones for all the joints.
