Comparing of the Processes of the Isothermal Phase Transformations of the Type 50 CrV 4 Using Different TTT Diagrams and Applying FEM based phase elements

摘要

The application of the FEM based phase elements is very useful for evaluation of the effects of TTT phase transformations diagrams. The comparison of the different TTT diagrams of the same type of the 50 CrV 4 steels shows that fine differences are possible to be evaluated and approximated by this simulation. Examples are presented for the use of the multiple regression calculation applying the data of the suitable TTT diagrams.
