Virtual TTT Diagrams Generated by Multi-Linear Regression Analysis
The TTT (Time-Temperature-Transformation) phase transformation diagrams based on FEM based phase elements make it possible to create virtual TTT diagrams. In this case the virtual TTT diagrams are results of multiple linear regression calculations. The basic TTT diagrams are created on the basis of measured published data. Two created virtual TTT diagrams are presented for two different austenitisation temperatures. The results of calculations are compared to the measured ones.
