Abstract
The impact value. the interfacial shear strength. the tensile strength and the fracture strain of Nb/MoSi₂ laminate composites. which were associated with the interfacial reaction layer. have been investigated. Three types of Nb/MoSi₂ laminate composites alternating sintcred MoSi₂ layers and Nb foils were fabricated as the parameter of hot press temperature. The thickness of interfacial reaction layer of Nb/MoSi₂ laminate composites increased with increasing the fabrication temperature. The growth of interfacial reaction layer increased the interfacial shear strength and led to the decrcase of impact value in Nb/MoSi₂ laminate composites. It was also found that in order to maximize the fracture energy of Nb/MoSi₂ laminate eomposites. interfacial shear strength and the thickness of interfacial reaction layer must be secured appropriately.
