Název v původním jazyce

Identification of phases in titanium alloy and correlation between EBSD, High Voltage, Medium Voltage and Low Voltage BSE imaging

Popis výsledku v původním jazyce

The imaging of composite materials is steadily growing in importance and since the contribution of the multi-phase composites combining metallic and non-metallic is rising therefore imaging of these materials becoming more significant. When ceramic (or generally non-conductive) matrix contains metallic phase components problems with phase analysis due to charging of the sample is evident. Coating the sample with conductive layer is the standard solution which may obscure fine surface details. This problem can be reduced using electron microscopy at low landing energy while the information quality of signals usually connected with high landing energies is preserved. The aim of this investigation is to evaluate the possibility to distinguish different phases in intermetallic alloy Ti - 46Al - 7Nb - 0.7Cr - 0.2Ni - 0.1Si using energy filtered Low Voltage Backscattered electron images (impact energy less than 5 kV). Microstructure of the specimens was examined using an Electron Backscatter
