Microstructure and Tensile Properties of Yttria Coated-Alumina Particulates Reinforced Aluminum Matrix Composites

Zhiqiang YU , Gaohui WU , Longtao JIANG , Dongli SUN

材料科学技术(英文)

The liquid-phase coating method was used to deposit Y2O3 ceramic on the surface of α-Al¬2O3. The coated-Al2O3p/6061Al composites were produced using squeeze casting technology. The microstructure and tensile properties of the composites were analysed and studied. The results showed that the coated A...

Effect of Thermal Cycling Treatment on Microstructure and Mechanical Properties of AlNp/2024A1 Composite

Gaohui WU , Bofeng LUAN , Longtao JIANG , Dougli SUN

材料科学技术(英文)

The A1NP/2024 composite with a high volume fraction (50%) was fabricated by squeeze casting. Its mechanical properties were investigated by tensile tests at ambient temperature and the microstructure was observed by a transmission electron microscope (TEM). It was indicated that after six thermal co...
