Abstract
⺠It is concluded in this work that the fine needle-like particles formed during the solution treatment of the 356 type alloy are indeed β phase plates similar to those frequently observed in as-cast aluminium alloys but of much finer sizes, most likely formed by precipitation in the vicinity of the dissolving Ï phase particles. ⺠The crystal structure of the needle-like particles, as examined by selected area electron diffraction, can be essentially indexed as either the A-Centred Monoclinic lattice [18] or the Orthorhombic lattice [25]. ⺠The particles appear to co-exist in two distinct forms: single crystal particles and composite micro-constituent particles.
