Taschenbuch. Zustand: Neu. Neuware -Friction Stir Welding (FSW), an innovative type of solid state welding technique invented & developed by The Welding Institute (TWI), can present higher potential for magnesium alloys. Because, it utilizes a non-consumable rotating tool to produce frictional heat and thereby creating plastic deformation at the location of welding. FSW is termed as a novel free manufacturing technique because of its energy efficiency, friendliness to the environment. FSW is also preferred over fusion welding as it avoids the scenarios of poor solidification micro structure in the fusion zone and hot cracking. FSW utilizes a non-consumable rotating tool to produce frictional heat and thereby creating plastic deformation at the location of welding. Thus, even when the material is in the solid state, a joint is formed and the formations of non ¿ toxic fumes are completely avoided. Even though the wider use of Mg alloys requires feasible joining methods, there is still a lack of efficient & effective welding techniques for Magnesium alloys. High quality of welds, cheaper price, ability to weld various types of hard¿töweld metals & non metals is yet another reason for choosing FSW to join Mg alloys.Books on Demand GmbH, Überseering 33, 22297 Hamburg 192 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In this book, an attempt was put forward to formulate a Central Composite Design (i.e., CCD) based multi-objective numerical model using the technique of grey relational analysis, for optimizing the tool dependent parameters during the FSW of distinctive alloys of Mg namely AZ80A and AZ31B Mg, with the responses being the tensile strength and elongation percentage of the joints. Experimental works concentrating towards the sensitivity based analysis of the parameters during FSW of Mg alloys and their fine tuning related requirements for attaining superior quality Mg alloy joints have not been carried out so far. In this book, the objective based function was selected as the tensile strength of the attained AZ80A Mg alloy joints and 6 process parameters of the FSW (namely rotational speed of the tool, tool¿s traverse speed, force exerted axially downwards, shoulder & pin diameter of the employed tool and tool¿s hardness) were taken into consideration as the design related variables.Books on Demand GmbH, Überseering 33, 22297 Hamburg 240 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -En este libro, se ha intentado formular un modelo numérico multi-objetivo basado en el Diseño Compuesto Central (CCD) utilizando la técnica del análisis relacional gris, para optimizar los parámetros dependientes de la herramienta durante el FSW de aleaciones distintivas de Mg, concretamente AZ80A y AZ31B Mg, siendo las respuestas la resistencia a la tracción y el porcentaje de alargamiento de las uniones. Hasta ahora no se han llevado a cabo trabajos experimentales que se centren en el análisis basado en la sensibilidad de los parámetros durante la FSW de aleaciones de Mg y sus requisitos relacionados con el ajuste fino para obtener uniones de aleación de Mg de calidad superior. En este libro, la función basada en el objetivo se seleccionó como la resistencia a la tracción de las uniones de aleación de Mg AZ80A obtenidas y se tomaron en consideración 6 parámetros de proceso de FSW (a saber, la velocidad de rotación de la herramienta, la velocidad de desplazamiento de la herramienta, la fuerza ejercida axialmente hacia abajo, el diámetro del hombro y del pasador de la herramienta empleada y la dureza de la herramienta) como variables relacionadas con el diseño. Este libro también tiene como objetivo determinar las características relacionadas con la sensibilidad de los parámetros del proceso FSW y la previsión de los requisitos previos relacionados con el ajuste fino de estos parámetros durante FSW AZ80A aleaciones de Mg.Books on Demand GmbH, Überseering 33, 22297 Hamburg 224 pp. Spanisch.
