The Investigation of Microstructure of Pt/Ti Explosive Clad Interface

Abstract:

Article Preview

Microstructure in anchoring site of Pt/Ti explosive clad Plate was observed, tested and analyzed by analytical and high resolution transmission electron microscope, X-ray diffractometer, scanning electron microscope and energy-dispersive spectrometer. An intermittent micro-crystal layer was observed in anchoring area, with thickness of 2 um. The inner crystal size was from some nanometer. to hundreds of nanometer. Some crystal had defects in it, such as staggered layer. The layer was composed of metal compound, like PtTi,Pt5Ti3,Pt3Ti,Ti3Pt and etc. The direct Pt—Ti anchoring area, hexagonal Ti variation-orthorhombic crystal system, α″-Ti metastable martensite phase and bicrystals with partial deformation were also observed. The research of microstructure in anchoring area revealed the nature of explosive compound in metallurgical anchoring.
