Microstructural analysis of a grey cast iron self-ventilating brake disc

Micro-structural analysis of a grey cast iron self-ventilating brake disc.

The images show the presence of lamellar graphite (black colored, in the low magnification image) and a perlitic micro-structure (in the high magnification image with Nital 2% chemical etchant).
