In steel, the kinetics of the transformation of austenite (fcc iron) to pearlite (eutectoid phase of a + Fe,C) obeys the Avrami relationship. Data for the fraction transformed versus time from experimental measurements are given in Table 1 below. Table 1. Data for the conversion of austenite to pearlite. Fraction Transformed Time (s) 0.15 0.62 440 290 (a) What are the constants k and n if using the time in seconds? (b) Determine the total time required to transform 98% of the austenite to pearlite
