The kinetics of the austenite-to-pearlite transformation obeys the Avrami relationship

Using the "fraction transformed-time" data given here, determine;

(a) The value of the exponential constant n (with two digits after the comma; example: 1.00)

(b) The value of the pre-exponential constant k (with two digits after the comma; example: 0.55)

(c) The total time required (in hours with two digits after the comma; example: 2.28) for 90% of the austenite to transform to pearlite.

Fraction Transformed	Time (sec)
