Investigation of the Data-Requirement of ESTPHAD Phase Diagram Calculation Method

The so-called phase diagram is one of the oldest but at the same time one of the most useful method for the material science. The role of algorithms and software calculating the phase diagram have an extraordinary importance in the industrial and research-development applications because remarkable advantages can be obtained by installing these software or the detailed and exact data base developed by them into either the simulation programs or into the everyday production (process-control, checking). In our present paper, the investigation of data-requirement of calculation method of ESTPHAD phase diagram is described by processing binary-and ternary systems.
