    Abstract
  • Explosive consolidation technology is employed to prepare MoSi2P/Nb high-temperature composites. The microstructure features and mechanical properties of MoSi2P/Nb composites were also studied. The results show that there are three kind of microstructure features in the composites and the compactness of the composites increase from outer layer to inner layer. Cores of the composites exhibit as cast feature because the energy massed to the central of the powders. With increasing λ values, the compactness of MoSi2P/Nb composites increases——the relative density can reach as high as 95.4%. As a result, the compressive strength of the composites increases as λ increases. Based on the analysis, it is pointed out that the explosive consolidation technology can be used in the preparation of MoSi2P/Nb high-temperature composites.
