How does the addition of alloying elements change the recrystallization temperature?
Adding alloying elements raises the recrystallization temperature. They not only increase nucleation but also act as barrier to the growth of grains. What is the effect of increasing cooling rate on a) temperature of austenite transformation temperature of austenite transformation – rate of austenite to pearlite tranformation increases with lowering of transformation temperature. b) fineness of pearlite fineness of pearlite – the lower the transformation temperature the smaller the interlamellar spacing or better the fineness of pearlite.
