| This implies that after hardening these steels practically always contain some residual austenite. |
| The solubility of both C and N in austenite should be greater than in ferrite, because of the larger interstices available. |
| With hardening of steels, by chilling after previous heating, the structure is converted from austenite to martensite. |
| Premature austenite decomposition has been found to be detrimental to mechanical properties. |
| When carbon steel is quenched in the baths at constant temperatures, the velocity of austenite transformation is found to depend on temperature. |
| Aluminum is widely used as a deoxidizer and was the first element used to control austenite grain growth during reheating. |
