Diamond grits are brazed on the surface of 0Cr18Ni9 stainless steel wire by using Cu-Sn-Ti pre-alloyed powder as interlayer materials,thus producing diamond wire saw with a diameter of 0.8mm.Mechanical properties of steel wire and wire saws are obtained by tensile tests,and the crystalline structures of wire cross sections before and after brazing are analyzed.Fracture morphology of the wire is observed by using scanning electron microscope.Then the tensile fracture mechanism is analyzed.Results show that d...
