Abstract

The recrystallisation and precipitation behaviour of a quenched Al-Fe alloy (0.042 wt % Fe) during isothermal annealing was observed, after different amounts of plastic deformation, by microscopy and measurement of electrical conductivity. Three temperature ranges with different types of reaction can be distinguished with decreasing temperature: (i) The recrystallisation of solid solution; (ii) A two-step reaction: the recrystallisation is complete before precipitation starts; (iii) One-step reactions: characterised by a mutual influence of recrystallisation and precipitation.

The combined reactions can take place by two different mechanisms. These are continuous recrystallisation, by growth of sub-boundaries, with simultaneous precipitation and coarsening of particles, and discontinuous recrystallisation, by motion of high-angle boundaries dissolving dislocations and redistributing particles. Conclusions of practical annealing treatments are drawn from the knowledge of the micromechanisms.
