Engine Block
This micrograph highlights a region of the engine block made from high-silicon aluminum casting alloy. Within the aluminum matrix are finely layered, elongated structures (green) that help absorb and dampen engine vibration. These silicate formations are intricately distributed to reduce noise and mechanical resonance. The resulting microstructure plays a quiet but vital role—literally—in helping the engine operate smoothly, efficiently, and with minimal acoustic disruption.
