Correlation between microstructure and phosphorus segregation in a hypereutectoid Wootz steel
journal contribution
posted on 2009-05-01, 00:00 authored by Matthew BarnettMatthew Barnett, R Balasubramaniam, V Kumar, C MacRaeThe influence of bands rich in phosphorus on the microstructure of hypereutectoid Wootz steel implement is described. Electron probe micro-analysis is combined with optical microscopy. Phosphorus-rich bands are seen to correspond to regions of internal cracking, carbon depletion, and enhanced frequency of spheroidized cementite in place of pearlite. A rationale for the findings is presented in terms of the influence of phosphorus on the Fe–C phase diagram and on the rate of the eutectoid reaction.
