Experimental investigation and thermodynamic assessment of the Al–Er system

Assessment of Thermodynamic and Structural Properties of Al–Er liquid Alloy at Different Temperatures

“…Therefore, the model parameters obtained for the investigation of thermodynamic functions were also used for computation of structural properties. Equations (11) and ( 12) and parameters from Table 1 were used to compute the values of S CC (0) and S id CC (0) for Al-Er liquid alloy at 1873 K. The effect of ordering energy parameter, ∆ω, on S CC (0) was also studied by varying its values in the range ∆ω = ±4 and keeping the values of ∆ω AB and ∆ω AA constant. From Figure 7, it can be observed that on increasing the negative values of ∆ω, the negative deviation of S CC (0) from S id CC (0) gradually increases in the entire comcentration range indicating the increase in complex formation capability in the system.…”

“…Increased mechanical qualities of the materials, such as tensile strength, heat, corrosion and vibration resistances, and extrudability can be achieved by alloying Er with Al [4,5]. In this regard, the energetic of the Al-Er binary liquid alloys have been studied by several researchers [1,[5][6][7][8][9][10][11].…”

“…[8]. Recently, Xu et al [11] assessed the phase quilibria and thermodynamics of the system using experimental measurements and CALPHAD software. Thus, it can be concluded that the Al-Er system has drawn the considerable consent of researchers working in this field for decades.…”

Phase Equilibria of the Fe–Cr–Er Ternary System in the Range 973–1273 K

“…ODS steel is strengthened by dispersing oxide particles, which strongly impede dislocation motion and thereby increase the onset stress of plastic deformation and creep resistance [ 2 , 3 ]. ODS ferritic/martensitic steels containing 9–12 mass% Cr have been developed as fuel cladding material because of their high creep strength at elevated temperatures and adequate resistance to neutron irradiation embrittlement [ 4 , 5 , 6 , 7 , 8 , 9 ]. The performance of ODS steel largely depends on the particle size and stability of the dispersed oxide nanoparticles [ 10 , 11 ].…”
