I want to know the answer to the following question:
Allotrophy happens between what temperatures?
All the background I'm provided with is that "At a certain temperature, (usually between 1,500 °F (820 °C) and 1,600 °F (870 °C), depending on carbon content), the base metal of steel undergoes a change in the arrangement of the atoms in its crystal matrix, called allotropy.". Is that enough to answer the question?
Answer: yes
