Abstract
The excellent corrosion resistance of metallic glass alloys has been documented, but metallic glasses have limited commercial application. On the other hand, microscrystalline powders produced via rapid solidification technology (RST) can be consolidated easily into useful shapes using standard powder-metallurgy techniques. For this reason many investigators have studied the corrosion behavior of microcrystalline alloys produced via RST. The alloys that have been studied include Fe-Cr alloys, stainless steels and nickel base alloys. The purpose of this investigation is to study the aqueous corrosion behavior of microcrystalline boron-modified commercial PH stainless steels with and without Ti and correlate it to the microstructure and microchemistry of the alloy. B is added to promote the development of a homogeneous metastable phase after rapid quenching. Ti is added to precipitate TiB{sub 2} during transformation of the metastable phase into an aggregate of microcrystalline phases. In this manner Cr and Mo would be left in the matrix giving high corrosion resistance instead of being precipitated as CR and Mo borides. In addition, TiB{sub 2} will stabilize the ultrafine grain microsctructure providing superior mechanical pr
