粉末冶金法制备SiCp/Al2W3O12/Al复合材料及其热膨胀性能
Thermal Expansion of SiCp/A12W3O12/AL Composite Materials Fabricated by P/M Technology
摘要
Abstract
Suitable amount of negative thermal expansion materials Al2W3O12 was added to optimize the thermal expansion coefficient of SiCp/Al composite materials.Negative thermal expansion Al2W3O12 powders were firstly prepared by solid state reaction.By adding 10％,20％,30％ (volume ratio) Al2W3O12 to the SiCP/Al composite powders,SiCp/Al2W3O12/Al composites were fabricated by powder metallurgy (P/M)technology.The experimental results showed that the composites with uniform organization and relatively high density were obtained.In the temperature range from room temperature to 200℃,the thermal expansion coefficient of the composites with the same mass ratio of Al was effectively reduced by increasing the amount of Al2W3O12.关键词
