The phase transformations occurring in mechanically milled and annealed triclinic Al3Ca8 intermetallic compound have been studied. The Al3Ca8 phase transforms initially to the nanostructured monoclinic Al14Ca13 intermetallic during milling. The Al14Ca13 phase is metastable and transforms back to the Al3Ca8 compound during subsequent heating. The transformation starts at low temperature with the grain coarsening of the Al14Ca13 phase. At intermediate temperatures, the transformation from Al14Ca13 to Al3Ca8 occurs. The sequence is completed at high temperatures with the grain coarsening of the Al3Ca8 phase. (C) 2012 Elsevier B.V.
