a Pseudo-binary isopleth showing phase stability in the Al0.3Ti0.2CoFeNi system as a function of temperature and Ti mole fraction varying from Al0.3CoFeNi to Al0.3Ti0.36CoFeNi, b phase fraction versus temperature for Al0.3Ti0.2CoFeNi showing the expected equilibrium phases in the temperature range of 400–1600 °C, c pseudo-binary isopleth showing phase stability in the Ti0.24CoFeNi0.78 system as a function of temperature and Ti mole fraction ranging from CoFeNi to Ti0.3CoFeNi0.72, and d phase fraction versus temperature for the Ti0.24CoFeNi0.78 composition showing the expected equilibrium phases in the temperature range of 400–1600 °C.
