Fig. K. (cotilinued.) At 21 7U X the specimen is seen in the process of licing 

 converted to spheroidized cementite. The ccmentite (iron-carhide) which is the 

 lisht constituent is in the process of transforming from a laminated form to 

 small globules. Grain boundaries are still marked by accumulations of ccmen- 

 tite but this is spheroidizing. In the light patches stratification of Ferritc and 

 ccmentite is just visible.
