The improvement mechanism of mechanical properties of B4C ceramics by constructing core–shell powders

Abstract: B4C ceramics have been widely used in armor plate and cutting tools due to their high hardness. However, their poor sintering performance and low fracture toughness have limited their extended applications. In order to solve these problems, B4C@TiB2 composite powders with core–shell structure were prepared by a sol–gel method using B4C and TiCl4 as raw materials and then sintered by spark plasma sintering. The composite powders were characterized by X‐ray diffraction, X‐ray photoelectron spectroscopy, and scan… Show more
