Abstract

TiB₂–Ti metal–ceramic composites were produced by forced SHS compaction. The influence of superstoichiometric amount of Ti (6–20 wt %) relative to TiB₂ on the regularities of combustion and phase composition/structure formation of TiB₂–Ti composites was studied. It was shown that the phase composition of composites is inconsistent with the Ti–B phase diagram. The microhardness of composites was determined to drop from 34 to 18 GPa with increasing the binder content. Cutting properties of composites were evaluated.

TiB2-Ti的强制SHS压实:结构与性能

采用强制SHS压实法制备TiB2-Ti金属陶瓷复合材料。研究了TiB2的超化学量(6 ~ 20wt %)对TiB2 - Ti复合材料燃烧规律和相组成/结构形成的影响。结果表明，复合材料的相组成与Ti-B相图不一致。随着粘结剂含量的增加，复合材料的显微硬度从34 GPa下降到18 GPa。对复合材料的切削性能进行了评价。

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
