Phase decomposition and strengthening in HfNbTaTiZr high ... 15/02/2022 · The predicted phase diagram shows a strong phase separation tendency, i.e., the Fe-Cr alloy decomposes into Cr-rich and Fe-rich phases below about 750 K, in reasonable agreement with experimental measurements. Moreover, the magnetic effect induced horn-like distortion of the miscibility gap was correctly reproduced. Nickel Based Superalloys - University of Cambridge The Ni-Al-Ti ternary phase diagrams show the γ and γ' phase field. For a given chemical composition, the fraction of γ' decreases as the temperature is increased. This phenomenon is used in order to dissolve the γ' at a sufficiently high temperature (a solution treatment) followed by ageing at a lower temperature in order to generate a uniform and fine dispersion of strengthening precipitates.
