Modification of aluminium and aluminium alloys by AL-B master alloy

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...

Positron Lifetime Measurements of Subsurface Region in Aluminium Alloy and Aluminium Alloy Composite after Dry Sliding

This paper presents positron lifetime studies of the subsurface region of AK12 aluminium alloy and Al2O3-particle-reinforced AK12 aluminium alloy composite after sliding against steel in the pin-on-disc machine. The defect depth profile detected in the AK12 alloy extended up to 300 μm but for the composite AK12 the range of this profile was significantly shortened to less than ∼ 90 μm. The posi...
