105) Pure iron is the structure of

Answer is:

ferrite

Engineering Materials MCQ with Answers

106) The temperature at which ferromagnetic alpha iron transforms to paramagnetic alpha iron is

Answer is:

770°C

Explanation:

Below 773 Â°C (1,423 Â°F), alpha iron becomes ferromagnetic (i.e., capable of being permanently magnetized), indicating a change in electronic structure but no change in crystal structure.
