摘要: Near-eutectic Al–Si alloys were produced by conventional casting and spray forming resulting in microstructural differences due to process dependent cooling rates. The as-sprayed alloy exhibited fine equiaxed Si particles uniformly distributed throughout the matrix contrast as-cast alloy, which acicular morphology with relatively large needle-like particles. effect of on stress distribution was estimated simulating uni-axial tensile loads microstructures using Object Oriented Finite Element code (OOF2). Microstructures experienced low uniform distribution, while significantly influenced orientation needle shaped silicon
