(PDF) TRANSFORMATION DIAGRAMS OF SELECTED STEEL

Therefore, both deformation CCT diagrams and, for reference purposes, CCT diagrams without deformation were determined for a selection of heat-treatable steels (34CrMo4, 42CrMo4 4140 Steel Phase Diagram - Wiring Diagram PicturesThe calculated response was subsequently tested using the experimentally measured CCT data for a different AISI steel. As the characterization of continuous cooling kinetics requires knowledge of the phase diagram, a mathematical model based on thermodynamic equations is used to derive the phase diagram for this steel. 42CrMo4 / 1.7225 - SteelNumber - Chemical composition Chemical composition of steel 42CrMo4 (1.7225), Standards of steel 42CrMo4 (1.7225) Mechanical Properties of steel 42CrMo4 (1.7225) Equivalent grades of steel 42CrMo4 (1.7225) steel 42CrMo4 (1.7225) Tensile Strength, Elongation, Proof strength , Hardness

CCt Curve (continuos cooling transformation)

Apr 28, 2016 · Introduction CCT Diagram for Fe C Carbon Contain and Its Effect On Mechanical Properties Factors Affecting CCT Curve Reference 3. There are two types of CCT diagrams Plot of (for each type of transformation) transformation start, specific fraction of transformation and transformation finish temperature against transformation time on each Continuous Cooling Transformation (CCT) of Austenite Efforts were made to derive CCT diagram from the available TTT diagrams. Two methods, one the graphical method of Grange and Kiefer, and the other due to Avrami rule made assumptions, which are not completely valid, were adopted but proved unsatisfactory, though reasonable success is achieved in getting the transformation start curve in the ferrite-pearlite reaction range. Continuous Cooling Transformation Diagrams Gear These diagrams allow the prediction of hardness and microstructure in the center of any diameter bar. This is also the most common method for displaying CCT diagrams. Figure 1:CCT diagram for AISI 1060 steel. Figure 2:CCT diagram for AISI 5160 steel. As can be seen in the diagrams, the AISI 5160 steel has a greater hardenability (Figure 2).

As a rule, percentages of two principal elements are shown on the horizontal axis of a gure, while temperature variation is shown on the vertical axis. However, the constitutional diagram of a pure metal is a simple vertical line. The constitutional diagram for commer-cially pure iron is
