Abstract

Porous high-N austenitic stainless steel was fabricated via powder metallurgy and its microstructure and properties were investigated. Results show that high temperature nitridation process promotes the phase transformation of the stainless steel from duplex phase to austenitic phase. Precipitations with different morphologies were observed in the microstructure. XRD results and TEM results identified that both the two precipitates with different morphologies are all CrN phase. With the increasing pore-forming agent the porosity of the prepared alloy increased, which could result in degradation of mechanical properties and corrosion resistance. The superior mechanical property of porous alloys fabricated by this method might be ascribed to the effect of solid solution strengthening of the solute N and precipitation strengthening of nitrides. With the increasing porosity, both of the corrosion tendency and corrosion rate increased for the as-fabricated porous high-N austenitic stainless steel. Among others, the alloy with 10% (mass fraction) pore former exhibits the best corrosion resistance. Besides, the increase of sintering temperature can enhance the densification of the as-prepared alloy, thus improves its corrosion resistance.

Key words: metallic materials high nitrogen austenitic stainless steel powder metallurgy porous mechanical properties corrosion resistance
