WebDec 2, 2009 · O ver the last 80 years, much experimental work has been conducted to construct time-temperature-transformation (TTT) diagrams of various steels.[1–5] These diagrams display the initiation of the various possible transformations and typically consist of two C-shaped start curves, which are separated by a region that is called the bay.The … WebTemperature–time–transformation (TTT) diagrams are an essential tool for interpreting the resulting microstructures after heat treatments. The present work describes a novel proposal to predict TTT diagrams of the γ′ phase for the Ni-Al alloy using artificial neural networks (ANNs).

WebExplain Construction of TTT Diagram This diagram is also known as Isothermal Transformation diagram. Davenport and Bain were the first to develop the TTT diagram of eutectoid steel. They determined pearlite and bainite portions whereas Cohen later modified and included M S and M F temperatures for martensite.
