1.In incremental launching method of bridge construction, what are the measures adopted to enhance sufficient resistance of the superstructure during the launching process?
2.The kinetics of the austenite-to-pearlite transformation obey the Avrami relationship. Using the fraction transformed-time data given below, determine the total time required for 95% of the austenite to transform to pearlite:
Fraction Transformed Time (s)
0.3 290
0.6 430
