Modelling of Precipitation Hardening in Casting Aluminium Alloys

Precipitation hardening, because it involves the hardening of the material over a prolonged time, is also called age hardening, or ageing. By the appropriate heat treatment of precipitation hardening, the strength or hardness of some heat-treatable aluminium alloys can be enhanced by the formation of nano-meter sized second-phase precipitated particles within the original phase matrix. The fine...

Nuclear orientation experiments on cerium intermetallic compounds

2014 Nuclear orientation experiments on In3Ce, Pb3Ce, Sn3Ce show that the first compound is well ordered, that Sn3Ce is a Kondo lattice and that further experiments must be performed in order to confirm the Kondo state of Pb3Ce. A simple interpretation is proposed to explain the behaviour of these abnormal compounds. LE JOURNAL DE PHYSIQUE LETTRES TOME 39, 1 er MARS 1978,

Intermetallic Phases Examination in Cast AlSi5Cu1Mg and AlCu4Ni2Mg2 Aluminium Alloys in As-Cast and T6 Condition

Precipitates and intermetallic phases in precipitation hardening Al–Cu–Mg–(Li) based alloys

The present study contains a critical review of work on the formation of precipitates and intermetallic phases in dilute precipitation hardening Al–Cu–Mg based alloys with and without Li additions. Although many suggestions for the existence of pre-precipitates in Al–Cu–Mg alloys with a Cu/Mg atomic ratio close to 1 have been made, a critical review reveals that evidence exists for only two tru...

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...
