Abstract

Corrosion rate, (CR), compressive strength (CS), and percent strain were determined for different microstructures generated by heat-treating a newly designed 7.5Mn-5Cr-1.5Cu alloy white iron intended to be used for making castings to resist aqueous corrosion under marine conditions. The microstructures were characterized on the basis of size, shape, and distribution of the second phase, which in the present study comprised dispersed (DCs) and massive carbides (MCs).A new term, “distribution factor” (DF), has been evolved to characterize DCs. This factor proved useful in establishing a relationship between microstructure and CR, which can be represented by the expression CR = [C1 + C2(VMC) + C3(VMC)2] * (DF)4
