The partial isothermal section of the phase diagram of the Nd-Al-Si ternary system at 500°C (50 at.% Nd or less) has been investigated by X-ray diffraction analysis, differential thermal analysis, scanning electron microscopy and electron micro-probe analysis. The existence of six binary compounds, αNd2Si3, βNdSix (x≤1.8≤2.0), NdAl, NdAl2, NdAl3 and αNd3Al11, and three ternary compounds, NdAl2Si2 (γ), NdAl1.75Si0.25 (δ), NdAl1.25Si0.25 (η), was confirmed. The ternary compound NdAl1.5Si0.5 was not found in this section. This isothermal section consists of 11 single-phase regions, 21 two-phase regions and 11 three-phase regions. The compound NdAl1.25Si0.25 has a large homogeneity range, while the other ternary compounds are non-solubility compounds.

The isothermal section of the Nd-Al-Si ternary system at 500 °C has been investigated using differential thermal analysis, X-ray diffraction analysis, scanning electron microscopy and electron micro-probe analysis. Four ternary intermetallic compounds were confirmed: NdAl2Si2 (τ1), hP5-CaLa2O2 structure type, Nd 2Al3Si (τ2), hP3-AlB2 structure type, NdAl1-x Si1+x, 0.25 ≤ x ≤ 0.3 (τ3), tI12-αThSi2 structure type and Nd 2Al1-x Si1+x, 0 ≤ x ≤ 0.2, (τ5), oS8-CrB structure type. A new ternary intermetallic phase (τ4) was found: Nd4Al3Si3, orthorhombic oS20, isotypic with Pr4Al3Ge3.
