Effect of alloys additions on the interlamellar spacing of pearlite

The spacing of pearlite was measured to investigate the effect of, alloying elements on this parameter using high purity plain carbon, 2 % Co, 2 % Si, 1 % Cr and 0.3 % Mo eutectoid steels. The investigation revealed that the addition of these alloying elements increases the spacing of pearlite at a given undercooling.
