| The equilibrium diagram does not tell us what form is taken by the ferrite or cementite ejected from the austenite on cooling. |
| When the temperature has been lowered sufficiently, the remaining liquid solidifies as a eutectic structure of austenite and graphite. |
| This high temperature treatment produces uniform austenite of rather large grain size. |
| Aluminum is widely used as a deoxidizer and was the first element used to control austenite grain growth during reheating. |
| The solubility of both C and N in austenite should be greater than in ferrite, because of the larger interstices available. |
| Any retained austenite in the steel microstructure can transform under mechanical loading to martensite with a resulting increase in volume. |
