Engine Block
This micrograph reveals the cast aluminum-silicon alloy used in the engine block, away from the piston cylinders. The orange-colored matrix represents aluminum grains, while fine silicate structures—appearing like necklaces—decorate their boundaries. These silicates strengthen the material at the grain edges, improving resistance to thermal fatigue and mechanical stress. The uniform distribution of phases makes this alloy ideal for structural regions of the engine where durability is essential.
