ML00070 — Automotive Light Alloy Wheel Repaired By WeldingM - Aluminum Silicon MagnesiumP - RimAp - AutomotiveCd - Removed From Service
Micrography of the cast rim, base metal, showing the dendrites of alpha aluminum and interdendritic eutectic Si/alpha, silicon particles in a coalesced condition that suggests a solution annealed treatment. After etching it is possible to identify a transgranular precipitation (aging) and a dark FeSiAl phase (neddles).
