Microstructure formation in Ti–Si composite subjected to high temperature gradients

Abstract Titanium eutectic composite Ti–Si–Al–Zr alloy castings were subjected to high thermal loads and temperature gradients to simulate extreme conditions of a gas turbine component. The microstructure of the affected zones was studied and characterized. The results can be applied to the development of a new generation of heavy-duty components with properties exceeding known cast titanium alloys and intermetallics.
