Webplexion TTT diagrams is likely to have an important impact on the field of grain-boundary engineering, ... Interfaces such as grain boundaries can also exhibit phase-like behavior [2], transforming from one equilibrium state to another as a function of thermodynamic variables in a process known as a complexion transition [3]. WebThe (strongly simplified) TTT diagrams show not only what you will get, but also that by alloying one can indeed move the pearlite / bainite noses to the right, i.e. to larger times as claimed above. These curves once more, contain a hell of a lot of extremely useful information. They are complex - yes!
