Abstract
estimated. Microexamination of samples was also done on the steel containing 0.22 wt % C to 0.36 weight percent of carbon. after normalizing at 7000C, 8000C and 9000C respectively. From the results, significant microstructural modifications due to heat treatment were noticed. The as- rolled 0.22 %C and 0.24 %C respectively consist of little pearlite regions in ferrite matrix. While the 0.36 %C consist of uniformly distributed pearlite regions (dark) in ferrite matrix (white) especially at austenization temperature of 8000C and 9000C above the upper critical temperature for all the steel grades. While those normalized at 7000C were fine pearlites, with varying amounts of spheroids of ferrite nucleated within the matrix.
