Abstract
The annealing of the melt-spun ribbons of Al - Li - Ti alloys at 200°C reveals the cellular microstructure. Due to a partition coefficient much larger than unity and a low diffusion coefficient, the titanium atoms remain essentially inside the cells and they repel the precipitation of the δ'- Al3Li metastable compound in the intercellular space.
