Question:
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 temperature as the temperature at which the impact energy is 20 J?
Step by Step Answer:
a The plot of impact energy versus temperature is shown below b The average of the maximum and mini...View the full answer
