Creep of Aluminium and Aluminium Alloys

This chapter constitutes an introduction to creep and to the creep response of Aluminium and its alloys. Its major goals are: to provide basic information on creep and its mechanisms to give a description of the more extensively used mathematical relations among creep variables (time, stress and temperature) to illustrate the creep response of pure Aluminium and of Al-Mg alloys to provide a syn...

Metallography of Aluminium alloys

This lecture aims at providing a survey of the metallographic techniques available for the examination of aluminium and its alloys. The information must be sufficient to be sure that the students and the users are able to choose the most suitable technique to solve their problems in the examination of samples. The lecture should contain a direct understanding of the main problems in the metallo...

Recrystallization Behavior of Commercial Purity Aluminium Alloys

Modelling of friction for high temperature extrusion of aluminium alloys

During high-temperature ball-on-disc tests of aluminium against steel, hot aluminium deformsand wear track evolves. The individual contributions of ploughing and shearing to theapparent friction and the contact pressure are unknown. The aim of this chapter was todevelop a model capable of determining these parameters. It was found that during high-temperature ball-on-disc tests,...

Numerical Modelling of Drawbeads for Forming of Aluminium Alloys

The drawbeads in stamping tools are usually designed based on experience from the forming of steel. However, aluminium alloys display different forming behaviour to steels, which is not reflected in the drawbead design for tools used for stamping aluminium. This paper presents experimental results from different semi-circular drawbead geometries commonly encountered in automotive dies and compa...
