High temperature laser-scanning confocal microscopy for the in-situ investigation of grain growth and phase transformations in intermetallic γ-TiAl based alloys

Journal Article


Abstract


  • Solid-state phase transformations and grain growth in an intermetallic γ-TiAl based alloy were examined using a confocal laser-scanning microscope. This apparatus allows the in-situ visualization of the microstructural development at high temperatures. The sample is thus placed into a furnace and a predetermined temperature profile is followed, while the surface is scanned using a laser. The contrast is gained by the thermal etching.
