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 Ti₄C₂S ₂, 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 Mn ₃N 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.
