With the investigated subject of 82B rod,the interlamellar spacings of pearlite at different isothermal transformation temperatures and different cooling rates during continuous cooling transformation were measured,and the effect of the isothermal transformation temperature and cooling rate on the interlamellar spacing was analyzed quantitatively.Moreover,the relationship models between undercooling and interlamellar spacing were presented by data regression.The experimental results show that the relationship between undercooling and reciprocal interlamellar spacing remains linear when the undercooling is not very large,or else,the interlamellar spacing tends to be constant and the relationship will deviate from linearity.
