Abstract

Methods for the production and application of ultrafine β silicon carbide fibers for hardening metal matrix composite materials based on Al and Mg are developed. The fundamental possible application of the fabricated fibrous silicon carbide for creating Al–SiC and Mg–SiC composites by liquid-phase stirring without additional wetting reagents under a layer of protective fluxes at the melting temperature of the matrix alloy is shown. Ultrafine SiC is found to be uniformly distributed over the composite volume. The microhardness of the sample surface increases with the silicon carbide content as compared to the initial materials and composites made from other silicon carbide modifications.

超细纤维β碳化硅对轻金属和合金的硬化

摘要

提出了一种用于硬化基于Al和Mg的金属基复合材料的β超细碳化硅纤维的生产和应用方法。显示了在基体合金的熔化温度下，在没有保护剂的情况下，通过液相搅拌在不添加其他润湿剂的情况下，通过液相搅拌制造铝碳化硅和镁铝碳化硅复合材料的基本方法。发现超细SiC均匀分布在复合材料体积上。与初始材料和由其他碳化硅改性制成的复合材料相比，样品表面的显微硬度随碳化硅含量的增加而增加。
