TALAT Lecture 1501: Properties, Characteristics and Alloys of Aluminium TALAT Lecture 1501: Properties, Characteristics and Alloys of Aluminium

Description

This lecture provides a survey of the aluminium alloys available to the user; it describes their various properties; it gives an insight into the choice of aluminium for a proposed application. In the context of this lecture not every individual alloy and its properties have been treated in detail, but rather divided into alloy types with reference to the most commonly used alloys. For further details on alloy properties the reader is referred to available databanks like ALUSELECT of the European Aluminium Association (EAA) or to the European and national materials standards. Good engineering background in materials, design and manufacturing processes is assumed.

FORMGRIP closed cell aluminium foam FORMGRIP closed cell aluminium foam

Description

Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% of pre-oxidised titanium hydride is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a relatively fine and uniform cell structure.

Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE) Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)

Description

FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly interconnected, angular pores. Wash out is slow, and can be improved by longer sintering which gives thicker necks between salt grains and hence more interconnection of pores in the reticulated structure. FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor.

Open-celled aluminium foam Open-celled aluminium foam

Description

Although the processing route is complicated and the product expensive, there is a high degree of control over the cell structure of such foams and the final shape can be controlled to meet near-net-shape requirements.

Cross-section of an aluminium foam slab produced by gas injection Cross-section of an aluminium foam slab produced by gas injection

Description

This is a continuous casting process which obviates foaming agents and the restrictions that they impose on temperature and processing time. However, molten metal drains through the structure due to gravitational forces and the resulting foam has a pronounced density gradient.

Solid-gas eutectic solidification (Gasar) aluminium foam Solid-gas eutectic solidification (Gasar) aluminium foam

Description

The metal to be foamed is melted in an autoclave with a controlled pressure of hydrogen, so that the melt becomes saturated with hydrogen. The melt is then directionally solidified and as it cools through the solid-gas eutectic point, it becomes supersaturated. A two phase solid/gas mixture is simultaneously formed from the melt, yielding an anisotropic porous solid with cylindrical pores oriented in the solidification direction.

Alporas' closed cell aluminium foam Alporas' closed cell aluminium foam

Description

Additions are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% titanium hydride is then added to the melt, and this foams the melt by releasing hydrogen. The foamed melt solidifies to yield a closed cellular structure with an average cell size of 4.5 mm Additions are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% titanium hydride is then added to the melt, and this foams the melt by releasing hydrogen.

TALAT Lecture 2405: Fatigue an Fracture in Aluminium Structures

Description

This lecture outlines modern fatigue design procedures and standards, the respective background information; it introduces fatigue design by testing; it presents fatigue data analysis and evaluation; it covers safety and reliability issues in aluminium design. This material has been utilized together with further definitions for classification of structural details to provide a proposal supported by the European Aluminium Association as a National Application Document, which may also be considered for introduction into the actual standard when this will be converted from an ENV to an EN.
