Superplastic behaviour and mechanical properties of two phase TiAl alloys
High temperature plastic flow properties of two phase TiAl alloys containing 45 to 49 at.%Al have been investigated in thermo-mechanically grain refined materials in order to clarify the favourable microstructure and chemical composition for TiAl based superplastic materials. Grain sizes of thermomechanical treated materials and their grain size stability during subsequent high temperature defo...

متن کاملMechanical behaviour of Fe-C alloys during phase transformations
The mechanical behaviour of Fe-C aiioys have been determined in their phase transformation ranges during isothermal or anisothermal transformations. Two models an analytical model and a fii te element model have been used in order to calculate the behaviour of the material. Considering a macroscopic scale, these models show that the mechanical behaviour can be well described when an additional ...
متن کاملFirst-principles Study of the Mechanical Properties of TiAl-Based Alloys
TiAl-based alloys have been suggested as advanced high-temperature structural materials replacing the Ni-based superalloys, due to their low density, high modulus, good oxidation resistance and creep resistance. However, their poor ductility and toughness at low temperature limits their applications in industry. Generally, controlling the microstructure and alloying elements are the most useful...
