Intermetallic Alloys Ni3Si and Ni3(Si,Ti):Microstructures and Properties

摘要：

　　Laser cladding experiment was carried out with a 5 kW continuous wave CO2 laser by preplacing Ni75Si25 and Ni78Si13Ti9 powders onto Ni-based superalloy substrate.The microstructure of the specimens was monitored by using optical and scanning electron microscopy.The chemical compositions of the alloys and their phases were obtained using X-ray diffraction and energy dispersive x-ray spectroscopy.The phase transformation temperatures were determined by non-isothermal differential scanning calorimetry tests.The microhardness of the laser cladded sample was measured.
