Such superb synergies derive from the addition of aluminium to the HfNbTiV alloy, resulting in a negative mixing enthalpy solid solution, which promotes strength and favours the formation of hierarchical chemical fluctuations (HCFs). The HCFs span many length scales, ranging from submicrometre to ...
The enthalpy of the formation was determined for the quasicrystalline phase of the composition Al 62Cu 25.5Fe 12.5 and the ternary BCC solid solutions Al 35Cu 14Fe 51, Al 40Cu 17Fe 43, and Al 50.4Cu 19.6Fe 30. The measured enthalpy of formation of the intermetallic compound FeAl is in...
