摘要：

In　this　research,　Ti-Zr-Cu-Ni　quaternary　amorphous　alloys　were　used　for　brazing　Ti-6Al-2Zr-1Mo-1V　alloys　below　their　beta-phase　transformation　temperature　in　order　to　obtain　optimized　mechanical　properties.　The　microstructure　and　mechanical　properties　of　Titanium　alloys　lap　joints　was　investigated　by　scanning　electron　microscopy　(SEM),　X-ray　diffractometer　(XRD)　and　shear　strength　measurement.　Experimental　results　show　that　holding　time　and　brazing　temperature　are　two　key　issues　to　the　shear　strength　of　the　Titanium　alloys　lap　joints.　Furthermore,　it　was　also　found　that　Ti55Zr13Ni23Cu9　possessed　the　most　outstanding　shear　strength　under　brazing　temperature　of　930°C　and　holding　time　of　10　min.　The　shear　strength　of　brazing　Ti45Zr34Ni8Cu13　was　markedly　improved　under　the　conditions　of　rising　the　brazing　temperature　to　940°C　and　extending　the　holding　time　to　60min.
