The Use of Modelling Techniques to Describe Recrystallized Grain Size of Commercially Processed 6000 Series Aluminium Alloy Components
نویسنده
چکیده
The development of grain size during commercial thermomechanical processing of 6000 series aluminium alloy components has been investigated by combining physical experiments and modelling techniques. A range of grain structures was generated by varying both deformation temperature and heat treatment practice. The different deformation conditions were simulated by finite element modelling, which allowed parameters such as plastic strain, strain rate and deformation temperature to be subsequently extracted. An adaptive numeric technique (neurofuzzy modelling) was employed to describe the recrystallized grain size in terms of the process parameters, and its performance compared with that of an empirical relationship from the literature.
