Question

Answer the following questions using the data from the Charpy impact diagram below

69) Which material would be more ductile at -150 °C than at room temperature?

70) What is the glass transition temperature (Brittle to Ductile transition onset) for Nylon?

71) Which material would be equally ductile over the entire -150 to 100 °C temperature range?

72) Which is the most ductile polymer on the list?

73) What is the Ductile to Brittle Transition Temperature (onset) for mild steel?

a) -80 °C

b) -50 °C

c) 50 °C

d) there is no DBTT with mild steel

Please answer all of them without guessing!!! Thanks
