Abstract:

The Effect of Microalloying Elements and Compounds, such as Be, B, C, P, S, Ti, V, Cu, Zn, in, BN, VN, Mn₃N, LaN, MnS and Ti₄C₂S₂, Ranging in Amount from 0.005 to 0.2 at.%, on the α-Fe + FeLaSi Two-Phase Microstructure of a La(Fe_0.89Si_0.11)₁₃ as-Melted Specimen Was Investigated. The Addition of Mn₃N Was Found to Contribute to α-Fe Grain Refinement to a Certain Extent, but to Harm the Uniform Growth of the τ₁ Phase in the Stage of Subsequent Annealing.
