In　this　article,　in-situ　scanning　electron　microscope　characterization　of　the　tensile　properties　of　TiB/Ti-2Al-6Sn　titanium　matrix　composite　(TMC)　was　conducted　before　and　after　electroshocking　treatment　(EST).　After　EST,　the　tensile　strength　increased　by　113.2　MPa.　The　effect　of　EST　on　the　tensile　strength　and　fracture　behavior　of　TiB　was　investigated　using　in-situ　characterization　of　the　fracture　morphology　and　crack　propagation　path　of　the　matrix　and　TiB.　Before　EST,　TiB　fracture　introduced　cracks　that　extended　into　the　matrix,　resulting　in　material　failure.　After　EST,　the　refined　TiB　improved　the　bearing　capacity　of　the　matrix,　thereby　improving　TMC　strength.　Moreover,　after　EST,　the　cracks　were　introduced　into　the　matrix,　and　resulting　the　fracture　of　matrix　first.　With　an　increase　in　the　external　load,　cracks　in　the　matrix　were　observed　to　propagate　to　TiB,　and　the　refined　TiB　was　fractured,　detached,　and　pulled　out,　resulting　in　the　formation　of　pores.　Analyzing　the　propagation　path　of　the　main　crack　after　EST　showed　that　the　deflection　angle　of　the　main　crack　increased.　The　microstructure　of　the　fracture　surface　indicated　that　the　fracture　of　the　matrix　was　plastic,　whereas　that　of　TiB　was　brittle.　After　EST,　the　size　and　area　of　the　dimples　increased,　confirming　the　increase　in　plasticity.　The　results　revealed　that　the　comprehensive　mechanical　properties　of　TiB/Ti-2Al-6Sn　improved　after　EST.　Hence,　EST　is　an　efficient　method　for　tailoring　the　microstructures　and　mechanical　properties　of　TMCs.
