Eutectic Growth Suppression for Cooperative Strengthening and Anticorrosion of Ni–Fe–Cr–Si Alloy

Abstract

Electromagnetic Levitation

In their Research Article (10.1002/adem.202500508), Ying Ruan and co-workers investigate the competitive growth between the dendrite and eutectic in Ni₅₀Fe₂₀Cr₂₀Si₁₀ alloy using electromagnetic levitation technique. Their findings show that the increase in undercooling enhances the nucleation rate and growth velocity of the γ phase and impedes the formation of Ni3Si+γ eutectic, tending to the γ single-phase microstructure, thereby the alloy’s yield strength and anticorrosive property are enhanced.
