?-LiAlSiO4 negative thermal expansion network interlayer for C/C?Nb brazing joint

A negative expansion LiAlSiO4 (LAS) network has been developed for C/C?Nb joints to modify the residual stress. LAS network was sintered elaborately obtaining high strut strength and smooth surface. AgCuTi brazing alloy had good wettability on LAS and infiltrated into network with faultless interfacial joining. The effect of stiff network structure on the stress dispersion of composite joints was investigated innovatively. The shear strength of joints modified with LAS network raised to 45.5?MPa, which was 2.6 times superior to the joints without this interlayer.
