Question:
The following tabulated data were gathered from a series of Charpy impact tests on a tempered 4340 steel alloy.
Temperature (°C) _______________ Impact Energy (J)
0 .................................................... 105
-25 ..................................................104
-50 ................................................. 103
-75 ................................................... 97
-100 ................................................. 63
-113 ................................................. 40
-125 ................................................. 34
-150 ................................................. 28
-175 ................................................. 25
-200 ................................................. 24
(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 temperature as the temperature at which the impact energy is 50 J?
