Chapter 8, Problem 8.14(choose chapter or problem)
The following tabulated data were gathered from a series of Charpy impact tests on a commercial low-carbon steel alloy. Temperature (C) Impact Energy (J) 50 76 40 76 30 71 20 58 10 38 0 23 10 14 20 9 30 5 40 1.5 (a) Plot the data as impact energy versus temperature. (b) Determine a ductile-to-brittle transition temperature as the temperature corresponding to the average of the maximum and minimum impact energies. (c) Determine a ductile-to-brittle transition temperatureas the temperature at which the impactenergy is 20 J.
