Calculated Continuous Cooling Transformation Diagram For The Aisi 1045 Definition: stability of phases during continuous cooling of austenite. there are two types of cct diagrams. i) plot of (for each type of transformation) transformation start, specific fraction of transformation and transformation finish temperature against transformation time on each cooling curve. Calculated continuous cooling transformation diagram for the aisi 1045 steel. the three curves correspond to the minimum cooling rate needed to avoid pearlite formation (10°c s), the maximum rate.
Calculated Continuous Cooling Transformation Diagram For The Aisi 1045 The continuous cooling transformation (cct) diagram shown on figure 1, is a plot of temperature versus the logarithm of time for a steel alloy of definite composition. used to indicate when transformations occur as the initially austenitized material is continuously cooled at a specific rate; in addition, the final microstructure and mechanical. A continuous cooling transformation (cct) phase diagram is often used when heat treating steel. [ 1 ] these diagrams are used to represent which types of phase changes will occur in a material as it is cooled at different rates. these diagrams are often more useful than time temperature transformation diagrams because it is more convenient to. In the present study the austenite decomposition kinetics for a 1045 steel was modeled using a modification of the transformation equation proposed by li et al. [1]. the kinetics of the continuous cooling transformation were determined directly from an isothermal transformation diagram. In order to describe the different types of phase transformation and micro hardness of aisi 1045 steel treated by scih process, a continuous cooling transformation (cct) phase curve of aisi 1045 steel was carried out in the microstructure transformation model, which is depicted in fig. 2 (ref 13).
