摘要：

In this work, microstructure, mechanical and tribological properties of Fe-TiB2 sintered from in-situ nanocomposite powders were investigated. TiB2 particles in pressureless sintered (PLS) specimen were found to be as large as several mu m while those in spark plasma sintered (SPS) specimen were about 5 nm. Mechanical and tribological properties of the SPS specimen were superior than those of the PLS specimen, which may be due to the formation of the fine TiB2 particles. It was further noted that Fe-TiB2 composites were fragmented into particulate wear debris, resulting in a film formation that could suppress wear progression. The outcomes of this work may be useful to better understand mechanical and tribological properties of Fe-TiB2 nanocomposites, associated with the structures.
