Abstract

The effect of Si on the precipitation of the Laves phase in high purity 17Cr-0.5Nb ferritic stainless steel was investigated. Precipitation was observed using a scanning electron microscope and transmission electron microscope. Quantitative analysis of the amount of precipitates as Laves phase was performed. The precipitation rate of the Laves phase and the equilibrium amount of precipitates of the Laves phase increased with the amount of Si. A Si peak was detected in the Laves phase in 0.5Si steel by energy dispersive X-ray spectrometer analysis. It was revealed that precipitation of the Laves phase was promoted and the chemical composition of the Laves phase was changed by the addition of Si.
