摘要

采用传统的冷压+烧结和火花等离子烧结技术制备了Al-Si复合材料和Al-Si/ b4c复合材料。研究了粉末冶金工艺对合金密度、显微组织性能、硬度和横向断裂强度的影响。讨论了快速烧结技术之一火花等离子烧结相对于传统烧结的优点。青坯密度和烧结密度随b4c添加量的增加而降低。火花等离子烧结制备的样品的相对密度值可达96%以上。b4c颗粒聚集在主合金晶界和/或晶间孔隙中。与冷压+烧结样品相比，火花等离子烧结样品的硬度值提高了约40%。在含有5 wt.% b4c和10 wt.% b4c的火花等离子烧结样品中，横向断裂强度提高。

"Influence of spark plasma sintering and conventional sintering on microstructure and mechanical properties of hypereutectic Al-Si alloy and hypereutectic Al-Si/B4C composites "

Al-Si compacts and Al-Si/B 4 C composites were fabricated by conventional cold pressing + sintering and spark plasma sintering techniques. The eﬀects of powder metallurgy techniques on density, microstructural properties, hardness, and transverse rupture strength were investi-gated. The advantages of spark plasma sintering, which is one of the fast sintering techniques, over conventional sintering were discussed. Green densities and sintered densities were found to decrease with increasing B 4 C addition. The relative density values of the samples produced with spark plasma sintering are over 96 %. B 4 C particles were clustered at the grain boundaries of the master alloy and/or in the intergranular pores. An increase of approximately 40 % was determined in the hardness values of the spark plasma sintering samples compared to the cold pressing+sintering samples. Transverse rupture strength was increased in spark plasma sintering samples containing 5 and 10 wt.% B 4 C.

期刊介绍： Kovove Materialy - Metallic Materials is dedicated to publishing original theoretical and experimental papers concerned with structural, nanostructured, and functional metallic and selected non-metallic materials. Emphasis is placed on those aspects of the science of materials that address: the relationship between the microstructure of materials and their properties, including mechanical, electrical, magnetic and chemical properties; the relationship between the microstructure of materials and the thermodynamics, kinetics and mechanisms of processes; the synthesis and processing of materials, with emphasis on microstructural mechanisms and control; advances in the characterization of the microstructure and properties of materials with experiments and models which help in understanding the properties of materials.
