Aluminum Matrix Composites with Quasicrystalline Particles, Three Reinforcement Levels

Reinforced aluminum matrix composites with 2.5%, 5%, and 10% volume of quasicrystalline particles were produced by stir casting and rolling. The quasicrystalline Al61.7Cu25.5Fe12.3Mn0.5 alloy was obtained by conventional melting and milling, with microstructure analyzed by X-ray Diffraction and Scanning Electron Microscopy. The dataset likely contains results from hardness and microstructural analysis of these composites.

Use Cases

• Predicting composite hardness based on quasicrystalline particle volume fraction and processing method.
• Analyzing the relationship between particle distribution and the formation of pores or agglomerates in the aluminum matrix.
• Comparing the mechanical properties of quasicrystal-reinforced composites to those using traditional ceramic reinforcements like SiC and Al2O3.

Strengths

• Composites were produced with three specific reinforcement levels: 2.5%, 5%, and 10% volume of quasicrystalline particles.
• Microstructure was investigated using X-ray Diffraction and Scanning Electron Microscopy, and hardness was measured with Vickers Microhardness.
• The rolling process is reported to have promoted a significant increase in hardness compared to as-cast composites.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
