Piston Cylinder Outer Wall
This micrograph captures the outer wall of an aluminum engine block’s piston cylinder. The light beige background is the aluminum matrix, while the yellow, blob-like features are aluminum-silicate particles. This region is engineered for structural support and thermal diffusion, absorbing and spreading heat generated during engine operation. The microstructure balances toughness and strength while helping maintain cylinder alignment.
