1 Δεκ 2023 · EPMA and XRD analysis of annealed LaFeSi alloys confirmed that La–Fe–Si ternary system contained seven two-phase regions in the 1373 K isothermal cross-section: La 3 Si 2 + τ5, La 3 Si 2 + τ5, α-LaSi2 + τ4, Fe 2 Si + τ2, B2 + τ2, D03 + τ2, and τ1 + τ3, and four three-phase regions: La 5 Si 3 + La 3 Si 2 + τ5, La 5 Si 3 + La 5 Si 4 ...
1 Ιαν 2012 · The phase equilibria at 1173, 1373 and 1573 K in the ternary Fe–La–Si system and the vertical section diagrams along La (Fe 1−x Si x) 13 (0.07≦ x ≦0.40) and Fe 95 Si 5 –La 33.3 Fe 33.3 Si 33.3 (at. %) section were determined. The main findings in this study are as follows: 1.
15 Δεκ 2022 · As a promising candidate of magnetic refrigerant, La-Fe-Si has been a focus of research in the past decades, involving fundamental study, performance enhancement and application in refrigerator prototypes.

La(Fe,Si)13-based intermetallic compounds with field-induced first-order magnetic phase transition, together with Gd, Fe2P, and Heusler alloys, belong to the magnetocaloric materials considered as promising for use in active magnetic refrigerators (AMR) [8], [9].
7 Αυγ 2012 · suggested that τ 1 and τ 2 form by ternary peritectic reactions: (αFe) (or L Fe-Si) + L La + τ 3 ↔ τ 1 at ∼1392 °C and τ 1 + L Fe-Si + τ 3 ↔ τ 2 at 1350 °C. Here, L La and L Fe-Si stand for La-rich and La-poor liquids.
26 Ιουν 2017 · Instead, the as-cast La-Fe-Si alloys show a two-phase structure composed of α-(Fe,Si) and La-Fe-Si (Cu 2 Sb-type: P4/nmm) phases. According to the phase diagram, during equilibrium solidification, the α-Fe phase (primary phase) dendrites first grow from the liquid.
