Abstract

The ZrB ₂-20 vol.% SiC composites (ZS) were joined to themselves using an Ag-Cu/Ti filler alloy. A novel TiB whiskers (TiBw) array with high preferred orientation was in situ synthesized at the interface of ZS. Investigation showed that the produced AgCu ₄Zr together with sufficient Ti promoted dissolution of ZrB ₂, and subsequently led to the formation of TiBw array. The mechanical properties of ZS/ZS joint were improved by interfacial TiBw accommodation. The maximum shear strength of 146 MPa was obtained with the filler alloy containing 15 wt.% Ti.
