| Abstract |
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. |
